How to tell if gold is real? Have you ever found someone trying to sell gold jewelry or bars, and felt like the price was too good to be true? How do you know that you didnât just take a piece of silver and paint it gold? Gold has always held a special place in various cultures. From ancient times, it has been used as currency and in religious ceremonies. Image by Algirdas Gelazius via Shutterstock Girls hands with golden bracelets Because of limited mining, extensive worldwide use as a form of money, and skyrocketing price gold is highly valuable. Just like other precious gemstones and metals, gold is counterfeited in high volumes. Donât worry! With a few simple tests some of them cost zero dollars, you can steer clear of fake gold jewelry. One precious metal that humankind has used from the dawn of civilization is gold. Despite being relatively rare, it has been a universal currency in many cultures and societies. Because of its shiny yellow texture and incredible malleability, it has been a favorite for crafting jewelry and art pieces throughout history. Gold has been an integral part of Ancient Egyptian culture dating back to 3000 BC. The Aztecs used to consider it as the âgod excrement.â It was a rare material that was first mined from rivers, and then excavated from mines. Itâs been discovered all over the world â from remote locations like ancient Australia to enormous areas such as South Africa. Gold is edible ! and has been used as a garnishing element for food and beverages from ancient times. The Egyptians started it around 5,000 years ago and then it spread across the world â from Eastern civilization to Europe. Image by Eqroy via Shutterstock Chocolate eclair pastry with edible gold leaf Gold is a popular choice for people when they look for sustainable investment. This is because of its scarcity, which is low enough to make it desirable in todayâs society but not too low that it becomes useless. According to the World Gold Council, approximately 197,576 tonnes of gold have been excavated until 2019 since the beginning and the underground reserve is nearly 54,000 tonnes. Gold bars are traded at set weights like ounces or grams, but the coins that you can purchase on eBay are fun to collect. To understand the properties of counterfeits, you should know the composition of genuine items. The unit for measuring authenticity is Karat and you will find various denominations from 24 to 8 karat. A 24k gold article is pure as it has gold element in its composition. On the contrary, a 14k item contains only gold and the rest is a metal alloy featuring two or multiple metal items which could be silver, copper, nickel, and zinc. Image by Zlataky Cz via Unsplash Gold bullion coins and bars Your gold items like jewelry or coins will have a metal alloy because of the soft nature of 24k gold. Itâs too flexible to hold a firm shape. Remember that a jewelry piece or coin can be genuine without looking like gold. For example, white gold is 75% pure gold and 25% alloy of nickel and zinc. It imitates platinum but is similar to 18k gold. On the other hand, counterfeit gold articles are not gold at all. They are made of completely different materials and only have a thin gold coating on the exterior. Some common and popular imitation variations are Plating means adding a thin layer of gold over the existing metal, which is mostly silver or copper. Due to the use of chemical or electrochemical bonding, the coating lasts for years and does not chip away like paint or lacquer which can chip away. Plated gold bracelets Plated jewelry isnât as expensive as a solid gold item, but it still holds some value and creates a nice look for any kind of ornament. Gold-filled jewelry is a way for consumers to get the benefits of gold without paying the premium price. Itâs a way of bonding a layer of solid gold on a base metal, such as sterling silver or brass core. Itâs different from plating because it uses more than an atom-thick layer of 18-karat gold and has a much higher quality to it. This type is popular because it can be worn for years and never lose its luster, while plated jewelry will only stay shiny for a few years before it needs to be re-plated. Popular copper alloys bronze and brass, are the most common type of counterfeits out there. Between them, brass copper-zinc alloy has a wider use case for imitation gold because of retaining its gold-like color for longer than bronze copper-tin alloy. A copper-nickel alloy cupronickel also mirrors a golden color but itâs not used for making jewelry because of nickel allergies. In the United States, anything lower than 10k which means lower than of gold cannot be labeled as gold. That limit is 8k in Germany. Image by Suto Norbert Zsolt via Shutterstock The mineral pyrite also known as fools gold Foolâs gold is a nickname for an iron sulfide called pyrite. People often mistake it as the real deal because of its metallic sheen and brass-yellow color. However, this mineral is brittle and yields powdery residue when scratched. Can you tell if gold is authentic or fake just by looking at it? No. But there are some things to look for that might offer a clue, and weâre going to get into the details. There are some telltale signs that your gold might not be real if youâre looking closely enough Not a super reliable test because only untainted gold does not change its color over time. Anything made of 24 karats gold shows a nearly orange-yellow color and it does not change much under normal circumstances. Jewelry made of 18k a rich buttery color or 14k gold a straw yellow color will change color over time because of the copper or silver alloy in them. However, wearing fake gold jewelry items will turn them dark pretty fast as they contain brass or steel. The one general rule for gold is its appearance gold has a >metallic luster> and its surface should not show any signs of corrosion. Although external elements can tarnish gold over years of use. It does come in different colors, but it should always have a uniform finish. Look for the marking on the clasp or inner band of a jewelry piece as it indicates the gold percentage in that is an international standard for denoting the purity of valuable metals. However, itâs not foolproof since anybody can engrave those markings. On the other hand, letter markings refer to mostly gold-plated jewelry, which is not real. The markings for the Karat system are 24k 99923k 91620k 83418k 75015k 62514k 4179k 3758k 333 The markings mean that 24k gold has of gold while the 8k contains only gold. In the United States, anything less than 10k is not considered gold while 8k is the lowest limit in German markers. Image by Arvind via Wikimedia Commons Gold ring with carat inscription Sometimes the stamp will be in a different location but itâs always worth looking to see if there are any markings at all. If you see any of the following letter markings on a piece of jewelry, avoid it because itâs not genuine. GP Gold-platedGE Gold ElectroplatedGF Gold FilledGEP Gold ElectroplatedHGP Heavy Gold-platedHEG Heavy Gold Electroplated These letter markings make it clear that these pieces only have a gold-like appearance because of the plating. The base will be some kind of other materials, such as silver, copper, or nickel. This is a simple test to see if your gold items have been adulterated. Gold will not react with the skin and can withstand soaps, detergents, and many other substances that would make any other metal change color or even corrode into oblivion. Rub the gold gently with some skin to see if any reaction occurs! If there is no change at all, either on your skin or the gold piece, chances are high that your jewelry will stay beautiful for years to come. Fake ones will transform your skinâs contact point into green, black, or blue. Donât forget to wash your hands thoroughly because the chemical elements in makeup or liquid foundation can temper the results. However, this test is foolproof only for pure 24k or 23k gold pieces. For example, if you have a 15k gold piece which contains only of gold, it can still react with the skin because of other metal elements. Plated goldâs exterior coating will wear away over time since gold is soft and that layer is pretty thin. If you have been using any gold items for a while, inspect the edges and the parts that touch your skin or clothes. Seeing another color underneath means itâs fake or plated. Itâs also possible to check if your gold has been plated with silver by vigorously rubbing your fingers over it and seeing if you can feel a rough texture. If so, then thereâs no gold underneath; just paint. The weight and size are two more tests that will help solve the mystery of how to tell if gold is real. Gold is heavy and dense. It weighs more than other metals and this means itâs a great way to tell if your jewelry has been tampered with. Ellery bangles floral beautiful The weight of gold will always be the same at about grams per cubic centimeter cc. Other familiar metals are much lighter â lead is g/cc, copper is g/cc, and aluminum is g/cc. If the jewelry weighs less than what should be for its size, then thereâs a good chance that something has been added to make it seem bigger like brass or steel. Gold will not react with a magnet because itâs non-magnetic. If you suspect that your gold might be diluted, then try this out to see if the metal has any ferrous properties. Use a robust neodymium magnet because a kitchen magnet is too weak to attract the metal blends inside a gold item. Bring the magnet close to the piece. If it moves forward, you are dealing with a fake item. This is a simple test but in no way guarantees the authenticity of gold. Real gold items can be bonded with ferromagnetic metals, such as iron and nickel. On the contrary, counterfeits can contain non-magnetic metals like copper and stainless steel. To see if your gold is real, try scratching it with an unglazed ceramic. Push the item gently on the ceramic surface and drag it around a bit. If it leaves behind a yellow streak, you are looking at a genuine gold item. A brownish-black streak could mean itâs a knockoff or foolâs gold pyrite. A ceramic test does not damage the gold except for leaving a light scratch on the surface. Take a vial or jug and fill up at least half of it with water. The temperature of the water does not have any effect on this test, so you can use room temperature or lukewarm water. Drop your gold item gently into the water and see what it does. A genuine piece of gold is dense and heavy, so it will quickly sink to the bottom of the container. Counterfeits are likely to float or sink slowly. The density test involves how much a gold bar or coin weighs compared to how much water it displaces. If the item is genuine, it will be heavier than water, and the increase in weight is proportionate to the purity. If there are any other additives in your gold like copper, then it will be much lighter than it should be. You will need a kitchen scale, a container with measurement markings, and water for this test. Follow these steps Take the weight of your gold item in grams on the scale. Note it a cylinder or vial that has cubic centimeter or millimeter markings on it. Fill around half of it with water. Record the starting water a soft hand, drop the gold piece into the container and note down the new water the first reading from the second one and divide the itemâs weight by this number. The result should be close to g/mL, which is goldâs standard density. In comparison, copper has only g/mL of density. The density of 18k and 14k gold items are g/mL and g/mL, respectively. The densities of alloys vary depending on how much gold is present. How to tell if gold is real? When it does not react with any acidic element. So, you can use vinegar or nitric acid to find out its authenticity. Gold is almost inert, so vinegarâs acidic element cannot change its color or properties. Use white vinegar since itâs the most acidic of all types. Just add a couple of drops of vinegar to the jewelry piece and see if the color changes. Itâs fake if it does; otherwise, you have a real piece. Give it at least 15 minutes to ensure enough time for the vinegar to set in and cause a reaction. Nitric acid does not react with gold, but it can melt the common metals in fake items. Careless application may ruin the ornament. Use a touchstone or a jewelry engraver to create a tiny but slightly deep scratch in a part that is not easily visible. Pour a few drops of acid on the scratch mark and if it turns green or milk-white, the piece is not real. You can do the same test with aqua regia 75% nitric acid and 25% hydrochloric acid too, which can melt gold. Pour a drop on the scratch mark to see if it disappears. If it does, your jewelry piece is genuine. If you are still not convinced about these tests for how to tell if gold is real, try an electronic test. A Sigma Metalytics machine will give precise results in seconds. The machine uses electromagnetic waves to detect the resistance of the metals of an item. So, if your piece has a gold plating with copper or nickel underneath, this tool can detect that difference. Precious metal verifier However, the machine is accurate only for coins and bullions. For finding out the authenticity of a jewelry piece, use any of the gold testing machines available in the market. An XRF Spectrometer will give you the most accurate answer without damaging the prized possession in any way. You can examine any type of gold item with this machine. A spectrometer sends X-rays through any item to charge its atoms into a higher power level. When the charged atoms cool down, they release radiation, which the spectrometer can detect and analyze. Goldâs radiation is different from any other metal, so it will be easy to identify the authenticity of your item. Appointing a jeweler to test real or fake gold is ideally the best method. They are professionals who have been trained for it. They also have access to equipment and different chemicals that can determine if the weight, shape, color, or purity of gold are right. Image by Bibiphoto via Shutterstock Jeweler inspects silver ring with acid Many jewelry stores offer testing services for a small fee. This fee is well worth the peace of mind to know that your precious metals are not gold fillers or less expensive metals. We donât highly recommend these tests because they donât give conclusive results. However, they cost nothing and in no way damage your precious gold. So, why not give them a try? Strike the gold piece with a metal object and listen for how it sounds. Gold makes a high-pitched, sonorous sound that rings on for a long time. Other gold-lookalike metals like copper or zinc will create a duller and shorter sound. However, you cannot completely rely on the result because the sound of a 24k and 18k article will not be the same, although both are genuine. You can check the authenticity of gold by biting it, which is not reliable but very popular. You must have seen Olympians biting their gold medals. This is done because gold is a very soft metal, so it can be easily bitten and the teeth marks will appear on the surface. Athlete biting gold medal The purer the piece, the deeper the teeth marks will be. The texture of gold is also much smoother than other metals, such as silver and nickel, making it easier to chew and identify in comparison. If your gold items pass the tests mentioned above, then congratulations! You can now wear it with pride knowing that the beautiful items are not just for show but hold real value. If, however, the DIY methods canât clear your confusion about how to tell if gold is real, try to get a second opinion from someone who knows about these things or take a professional service. A. A fast way to identify whether something contains imitation gold would be to look closely at the color of the metal on especially bright surfaces like light bulbs. Real 24 karat gold has an almost orange-yellow hue on such surfaces while inexpensive metals often display a yellow-gold shade. Ways to test if something made from gold is fake include whether or not it rusts or feels heavy compared to its size. Commonly, jewelers will test gems by using acid because gold is non-reactive. A. No. Gold is naturally a non-magnetic metal. So, a magnet cannot attract a 24k or 22k gold item. But 18k, 14k, or 10k gold items have a significant amount of metal alloy mixed in it. You can pull them out with a magnet if those metals are ferromagnetic. A. The magnet and acid tests are the best way to tell the difference between unadulterated gold and gold-plated items. A piece of solid gold will not react to these tests. Checking the weight is another good method since a piece of gold-plated item will be lighter than an authentic gold of similar size. Of course, the best way to get the correct result is to use a Sigma Metalytics machine or an XRF spectrometer. A. Check the hallmark and color. A bright orangish-yellow shade with letters or numbers, like â24kâ or â999â, stamped somewhere gives a primary indication about its authenticity. Also, it will show zero magnetism and no kind of acidic reaction. A. Using vinegar is the easiest method because we all have vinegar at home. You can also rub it with your skin to see the color of either your skin or the gold piece changes. A. To some extent, yes. Although you should not rely on the result completely and examine the items with other tests too. Forged gold will turn black or green because of the presence of other metals in it. Some counterfeits can create smoke or cause a cracking sound too. A. Without using any acidic liquid, you can check a gold itemâs authenticity by scratching it with a ceramic or testing it with a powerful magnet. Rubbing with the skin works too. You can also gently hit it with another metal to see if it produces a long sonorous sound. The bite test works too but it will leave teeth marks on the item.

Download Article Download Article How do you tell if gold is real, gold plated, or fake? By most international standards, anything with less than or 10 karats of gold is considered fake. To test your jewelry or gold at home, you can perform a few easy testsâmostly with items you already have, like water, vinegar, and magnets. You donât have to be a certified jeweler to get a good idea of whether or not your gold is real, and weâll give you step-by-step instructions to test your gold right now. 1 Drop the gold into a jug of water to see if it sinks. Get a container big enough to hold both the water and the gold youâd like to test. The water temperature you use doesnât really matter, so lukewarm water is fine. Real gold is a dense metal, so it falls directly to the bottom of the jug. Imitation gold is much lighter and floats.[1] Real gold also doesnât rust or tarnish when wet, so if you see a discoloration, you probably have plated gold. 2 Put a few drops of vinegar on the gold. Set your jewelry or gold piece onto a flat surface. Use an eyedropper to apply a bit of vinegar and let it sit for about 15 minutes. Real gold wonât change color, but fake gold will.[2] You can also submerge the gold in a glass container with vinegar for 15 minutes. This is a slightly riskier method because vinegar might damage semi-precious stones on gold jewelry. Advertisement 3 Find any noticeable discolorations where the gold has worn away. Gold is pretty soft for a metal, so plated gold often rubs away over time. The best places to check are around the edges of jewelry and coins. These spots often rub up against your skin and clothing throughout the day. If you see a different metal underneath the gold, you know your item is plated and not considered real gold.[3] For example, a silver coloring might indicate silver or titanium. A red coloring could mean copper or brass. EXPERT TIP Jerry Ehrenwald Former President, International Gemological Institute & Graduate Gemologist Jerry Ehrenwald, GG, ASA, is a graduate gemologist in New York City. He is the previous President of the International Gemological Institute and the inventor of Laserscribeâ , a means of laser inscribing onto a diamond a unique indicia, such as a DIN Diamond Identification Number.

Jerry Ehrenwald Former President, International Gemological Institute & Graduate Gemologist Our Expert Agrees Suspicious marks and discolorations around the edges of the item are often telltale signs that the gold is fake. However, if the item is not 24k gold, which is considered pure gold, it may tarnish over time as the base metals are exposed to oxygen. 4 Note any discolorations on your skin from wearing or holding the gold. Pure gold doesnât react with sweat or oil from your skin, so if you see black or green marks, they are from other metals. Silver leaves behind black marks and copper leaves behind green marks. If you see a lot of these marks on your skin, your gold may be less pure than you expect.[4] Keep in mind that most gold items are blends of gold and other metals. Even something like a 14K piece of jewelry, gold, can leave these marks. Use other tests as well to ensure your gold is authentic. 5 Hold a strong magnet up to see if the gold sticks to it. For this test, you need a strong magnet capable of pulling even metal blends. Move the magnet over the gold and observe how it reacts. Gold isnât magnetic, so donât be fooled by anything that sticks. If the magnet pulls the gold toward it, your item is either impure or a fake.[5] Regular kitchen magnets might not be strong enough. For better accuracy, buy a powerful neodymium magnet from a home improvement store. The magnet test isnât foolproof, since counterfeit gold can be made with non-magnetic metal like stainless steel. Also, some genuine gold items are made with magnetic metals such as iron. 6 Rub the gold on unglazed ceramic to see if it leaves a streak. Make sure youâre using an unglazed piece of ceramic since anything with a glaze could affect the test results. Drag your item across the plate until you see some fragments coming off the gold. If you see a black streak, that means your gold is not real. A gold streak usually indicates authentic gold.[6] Try getting an unglazed ceramic tile or a plate online or from your local home improvement store. This test scratches the gold a little bit but doesnât typically leave much noticeable damage. It is much safer than other tests involving scratches or acid. Another way to do this is by spreading some cosmetic foundation on your skin and dragging the gold across it after it dries. Fake gold usually reacts with the foundation, leaving a green or black streak in it. Advertisement 1 Look for an official number marking on the gold. The marking, or hallmark, tells you the percentage of gold in an item. The hallmark is often printed on jewelry clasps or the inner bands of rings. It is usually visible on the surface of coins and bullion. The stamp is a number from 1 to 999 or 0K to 24K depending on what kind of grading system was used.[7] Use a magnifying glass to help you identify the hallmark. It can be tough to make out by eye, especially on smaller pieces of gold such as rings. Older pieces of jewelry may not have visible hallmarks. Sometimes the hallmark wears off over time, while in other cases the jewelry never got a stamp. Hallmarking became common in the 1950s in some areas, but in India for instance, it only became mandatory in the year 2000.[8] 2 Use the number marking to determine how much gold is in your piece. Most coins and jewelry are not pure gold, so they have other metals mixed in. There are 2 different scales used to indicate this through the hallmark. The number rating system used in Europe runs from 1 to 999 with 999 meaning pure gold. The uses a scale from 0 to 24K, where 24K is pure gold.[9] The number rating system is easier to read than the karat rating system. For example, a rating of 375 means your item consists of gold. What number means gold depends on the country you are in. In the for example, anything 9K and under is not considered to be gold, even though a 9K bracelet consists of gold. Counterfeit pieces may have markings making them look authentic, so donât go solely on the hallmark unless youâre certain you are holding gold. 3 Check for a letter marking indicating that the gold isnât pure. Some of the common letters you may see are GP, GF, and GEP. These letters indicate that your gold piece is plated, which means the maker put a thin layer of gold over another metal, such as copper or silver. Your item has some gold in it, but it isnât considered real gold.[10] GP stands for gold plated, GF means gold filled, and GEP means gold electroplate. The markings vary a little depending on where the gold is from. For instance, gold from India contains a small triangle symbol indicating the government council responsible for the rating system. It then has a number rating and a letter code, such as K, for the jeweler. Advertisement 1 Weigh your piece of gold on a scale. If you have a decent kitchen scale, place the gold on it. Otherwise, jewelers and appraisers often can do it for you for free. Call around to different jewelry or appraisal stores to see which ones offer this service. Make sure you get the weight in grams rather than ounces.[11] You need the weight in grams to use in a calculation later. If the weight is in ounces, you wonât get an accurate result. 2 Fill a graduated cylinder halfway full with water. Choose a cylinder that is big enough to hold the gold. It needs to have measurement markings in milliliters mL or cubic centimeters cc. If you donât have a regular graduated cylinder, you could try using a kitchen measuring cup.[12] Vials with frequent millimeter markings on the side are useful for getting a more accurate measurement during the test. The amount of water you use doesnât matter that much as long as you leave plenty of space for the gold. If you fill the vial to the top, dropping the gold into it causes the water to spill. 3 Read the starting water level in the cylinder. Look at the markings on the cylinder, then record the water level. This measurement is very important for the test, so write it down. Make sure you have the vial on a flat, level surface in order to get as accurate a reading as possible.[13] Keep in mind that it doesnât matter if your vial is marked in milliliters or cubic centimeters. They are the same measurement, so either unit can be used in the test. 4 Drop the gold into the vial and record the new water level. Gently lower the gold into the cylinder to avoid losing any of the water. Let go of it right above the water to prevent splashing or getting your fingers wet. Then, read the markings again to get the second measurement.[14] Write the second measurement down on a piece of paper. Note that this is the second measurement, not the initial one. 5 Subtract the measurements to find the difference in the water level. To figure out how much water the gold displaced, subtract the initial measurement the smaller number from the final measurement. This gives you an answer in milliliters or cubic centimeters, depending on what measurement your vial lists.[15] For example, if you started with 17 mL fl oz of water that rose to 18 mL fl oz, that leaves a 1 mL fl oz difference. 6 Divide the goldâs weight by the difference in the water level. The density of the gold equals its mass divided by its volume. After calculating the density, compare the result to the standard density of gold, which is g/mL. If your number is way off, chances are you have a fake. Keep in mind, though, that some combinations of metals in fake gold can have a density similar to real gold.[16] For instance, you have a gold item that weighs 38 g oz and displaces 2 mL fl oz of water. Divide 38 by 2 to get 19 g/mL, which is very close to the density of gold. The standard density differs a little depending on the type of gold you have. For 14k yellow gold, itâs about to g/mL. For 14K white gold, itâs around 14 g/mL. A piece of 18K yellow gold has an average density from to g/mL. A piece of 18K white gold has a density from to g/mL. Any 22K piece of gold has a density around to g/mL. Advertisement 1 Purchase a gold-testing kit to get the acid you need for the test. Testing kits include various bottles of nitric acid for different types of gold. Some tests also include a flat rock called a touchstone you can use to scratch off some of the gold on your item. You may also see needles with samples of yellow and white gold to use as a comparison to your item.[17] Testing kits are available online. Also, check with local jewelry stores. Most jewelers use this test for its accuracy. 2 Create a small scratch on the gold using a sharp tool. Choose an inconspicuous location on the jewelry to make the scratch, such as underneath a clasp or an inner band. Then, use a sharp tool such as a jewelry engraver to dig into the gold. Scratch until you get underneath the top layer of gold. Expose a fresh layer of gold or any other metal underneath it.[18] Nitric acid tests require you to scratch your piece of gold. If the gold has personal value to you or you plan on keeping it, take it to a professional jeweler instead of doing the test yourself. 3 Add a drop of nitric acid to the scratch. Put on latex gloves and work in a well-ventilated room to avoid any issues with the dangerous acid. When youâre ready, look for the bottle of acid labeled for 18K gold. After setting the gold in a stainless steel container, place a drop of the acid directly on the scratch you made, then watch for it to turn a shade of green. If it turns green, you know right away your gold is fake.[19] Regular gold does not react to the acid, so your item might be gold plated or a low-purity blend of metals. A milk-colored reaction usually indicates gold-plated sterling silver. If the acid turns gold, you have gold-plated brass. 4 Scratch the gold on a touchstone to test its purity. If you think you might have real gold, rub it along the touchstone to create a streak of gold flakes. Add a drop of 12K, 14K, 18K, and 22K nitric acid to different parts of the streak. Check back after 20 to 40 seconds. Find the spot where the acid doesnât dissolve the gold to figure out what karat rating your item is.[20] The acids all increase in strength, so the acid used for 22K is stronger than the 12K one. If the 18K acid dissolves the gold but the 14K one doesnât, you know your item is probably around 14K.

Former President, International Gemological Institute & Graduate Gemologist Expert Answer Support wikiHow by unlocking this expert answer. With a magnifying glass, look for a purity hallmark from the manufacturer on the jewelry item. For example, if you own the purest gold, you should see hallmark â999â or â24Kâ engravings somewhere on the jewelry item. With older jewelry as an exception, typically, if you do not find a mark it may not be genuine gold. Suspicious marks and discolorations around the edges of the item in question can also be telltale signs the gold is fake. An easy at-home test is to see if the gold jewelry item sticks to a magnet. If the item sticks to the magnet, it may be fake or not 100% gold. Ask a Question 200 characters left Include your email address to get a message when this question is answered. Submit Advertisement When jewelers say that gold is 24K, they mean that the gold is pure with minimal traces of other metals. A piece of gold that is 22K is 22 parts gold and 2 parts another metal.[21] Most gold tests are imperfect, so you may need to go through several tests in order to decide if your item is authentic. You may have heard of the bite test where gold is real if your teeth leave a mark on it. Since most gold items consist of blends of harder metals, avoid the bite test to protect your teeth. Show More Tips Advertisement Nitric acid is strong and can burn your skin in addition to damaging a valuable piece of gold. If youâre worried about this, you can do a home test with vinegar, which is a milder acid, or you can let a professional jeweler or appraiser handle the nitric acid test.

If it floats, it's probably not real gold, since gold is very dense. You can also try holding a strong magnet, like the kind you can find at hardware stores, up to the metal to see if it sticks to it. If it sticks, it probably isn't real gold, since gold isn't magnetic. Alternatively, try rubbing the metal on a piece of unglazed ceramic to see if it leaves a gold streak, which could be a sign that the gold is authentic.
