How do you tell if gilt is existent, gold plated, or fake? By most international standards, anything with less than 41.7% or ten karats of gold is considered simulated. To test your jewelry or gold at dwelling house, you lot tin can perform a few easy tests–mostly with items y'all already accept, like water, vinegar, and magnets. You don't have to be a certified jeweler to become a good idea of whether or not your gold is real, and we'll give you step-by-step instructions to test your gilded right now.

1
Drib the aureate into a jug of h2o to run into if it sinks. Go a container big plenty to hold both the water and the gilded yous'd similar to test. The water temperature y'all utilise doesn't really thing, so lukewarm water is fine. Existent gilt is a dense metal, and then it falls directly to the bottom of the jug. Simulated gold is much lighter and floats.^[i]
- Real gold also doesn't rust or tarnish when wet, so if you lot run into a discoloration, you probably have plated gold.
two
Put a few drops of vinegar on the gilt. Gear up your jewelry or gold slice onto a flat surface. Utilise an eyedropper to apply a bit of vinegar and let it sit for nearly 15 minutes. Existent golden won't change colour, but false aureate volition.^[ii]
- You can too 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.

iii
Find whatsoever noticeable discolorations where the gilt has worn away. Gold is pretty soft for a metallic, so plated gilt often rubs abroad over time. The best places to bank check are around the edges of jewelry and coins. These spots frequently rub up against your skin and article of clothing throughout the mean solar day. If you see a unlike metallic underneath the gold, y'all know your item is plated and non considered real gold.^[3]
- For example, a silverish coloring might bespeak silver or titanium. A cerise coloring could mean copper or brass.

Our Expert Agrees: Suspicious marks and discolorations around the edges of the item are often telltale signs that the golden is false. However, if the item is not 24k gold, which is considered pure gilt, it may tarnish over fourth dimension as the base metals are exposed to oxygen.
4
Note any discolorations on your skin from wearing or belongings the aureate. Pure gilded doesn't react with sweat or oil from your pare, then if y'all encounter black or green marks, they are from other metals. Silvery leaves behind black marks and copper leaves behind light-green marks. If you see a lot of these marks on your skin, your gilded may be less pure than you wait.^[iv]
- Go along in mind that most gold items are blends of golden and other metals. Even something like a 14K piece of jewelry, 58.3% gilded, can go out these marks. Utilise other tests too to ensure your gold is authentic.
5
Hold a stiff magnet up to run across if the gilded sticks to it. For this exam, you lot need a strong magnet capable of pulling even metal blends. Move the magnet over the gold and observe how it reacts. Gold isn't magnetic, so don't be fooled by annihilation that sticks. If the magnet pulls the aureate toward it, your item is either impure or a fake.^[v]
- Regular kitchen magnets might not exist stiff enough. For better accuracy, buy a powerful neodymium magnet from a dwelling comeback store.
- The magnet test isn't foolproof, since counterfeit gold tin be made with non-magnetic metal similar stainless steel. Likewise, some genuine gold items are made with magnetic metals such as iron.
6
Rub the aureate on unglazed ceramic to see if it leaves a streak. Make sure you're using an unglazed piece of ceramic since anything with a glaze could touch on the test results. Drag your particular across the plate until you meet some fragments coming off the golden. If you meet a blackness streak, that ways your gilded is not real. A aureate streak commonly indicates authentic gilt.^[vi]
- Try getting an unglazed ceramic tile or a plate online or from your local dwelling improvement store.
- This examination scratches the aureate a picayune bit but doesn't typically go out much noticeable damage. It is much safer than other tests involving scratches or acid.
- Another way to do this is past spreading some cosmetic foundation on your skin and dragging the gilt across it after it dries. Simulated gold usually reacts with the foundation, leaving a green or blackness streak in it.

Wait for an official number marking on the gold. The marker, or authentication, tells you the percentage of gilt in an detail. 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 postage stamp is a number from ane to 999 or 0K to 24K depending on what kind of grading system was used.^[7]
- Use a magnifying drinking glass to help yous identify the hallmark. It tin be tough to brand out by eye, especially on smaller pieces of aureate such equally rings.
- Older pieces of jewelry may not have visible hallmarks. Sometimes the authentication 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 Bharat for instance, it simply became mandatory in the yr 2000.^[8]
ii
Apply the number mark to determine how much gilded is in your piece. Near coins and jewelry are not pure gold, and so they have other metals mixed in. At that place 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 significant pure gold. The U.Southward. uses a calibration from 0 to 24K, where 24K is pure gold.^[nine]
- The number rating organisation is easier to read than the karat rating organisation. For example, a rating of 375 means your item consists of 37.five% gold.
- What number means gold depends on the country you are in. In the U.S., for case, annihilation 9K and under is not considered to be gold, fifty-fifty though a 9K bracelet consists of 37.5% gilded.
- Counterfeit pieces may have markings making them look authentic, so don't go solely on the hallmark unless you're sure you lot are holding gilded.
3
Bank check for a alphabetic character marking indicating that the golden isn't pure. Some of the common letters you lot may encounter are GP, GF, and GEP. These letters indicate that your gold piece is plated, which means the maker put a thin layer of gilt over another metal, such as copper or silver. Your item has some gold in it, but it isn't considered existent golden.^[10]
- GP stands for gilded plated, GF ways gold filled, and GEP means golden electroplate.
- The markings vary a fiddling depending on where the gilded is from. For instance, gold from Bharat contains a small triangle symbol indicating the government council responsible for the rating organisation. It then has a number rating and a letter of the alphabet code, such as K, for the jeweler.

Weigh your piece of gold on a scale. If you have a decent kitchen calibration, place the gold on it. Otherwise, jewelers and appraisers ofttimes can practice it for y'all for costless. Phone call around to different jewelry or appraisal stores to run across which ones offer this service. Make sure you become the weight in grams rather than ounces.^[11]
- You demand the weight in grams to use in a calculation later. If the weight is in ounces, yous won't get an accurate result.
ii
Fill a graduated cylinder halfway full with water. Cull a cylinder that is big enough to concord the gold. It needs to have measurement markings in milliliters (mL) or cubic centimeters (cc). If you lot don't take a regular graduated cylinder, yous could endeavour using a kitchen measuring cup.^[12]
- Vials with frequent millimeter markings on the side are useful for getting a more accurate measurement during the exam.
- The corporeality of water you lot utilize doesn't matter that much as long every bit you leave enough of space for the aureate. If you fill the vial to the tiptop, dropping the gold into it causes the h2o to spill.
iii
Read the starting water level in the cylinder. Look at the markings on the cylinder, and so record the water level. This measurement is very of import for the test, and so write it downwards. Make sure you have the vial on a flat, level surface in order to go as accurate a reading equally possible.^[13]
- Keep in mind that it doesn't matter if your vial is marked in milliliters or cubic centimeters. They are the same measurement, so either unit tin 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. Allow go of it right above the water to prevent splashing or getting your fingers wet. Then, read the markings over again to get the second measurement.^[14]
- Write the 2nd measurement down on a piece of paper. Note that this is the 2nd measurement, not the initial i.
five
Decrease the measurements to find the difference in the water level. To figure out how much h2o the gold displaced, subtract the initial measurement (the smaller number) from the last 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 (0.57 fl oz) of water that rose to 18 mL (0.61 fl oz), that leaves a i mL (0.034 fl oz) divergence.
6
Carve up the aureate's weight past the difference in the water level. The density of the gold equals its mass divided by its book. Afterward calculating the density, compare the result to the standard density of gilt, which is 19.iii g/mL. If your number is way off, chances are yous have a fake. Keep in mind, though, that some combinations of metals in fake gold can accept a density like to real aureate.^[16]
- For case, you have a gilt item that weighs 38 k (1.3 oz) and displaces 2 mL (0.068 fl oz) of water. Dissever 38 by 2 to get xix thou/mL, which is very close to the density of gilded.
- The standard density differs a little depending on the type of gilt you lot have. For 14k yellow gold, it's about 12.9 to thirteen.6 m/mL. For 14K white gold, it's around fourteen g/mL.
- A piece of 18K yellow gold has an boilerplate density from 15.2 to xv.9 g/mL. A piece of 18K white gold has a density from 14.seven to xvi.9 g/mL.
- Whatever 22K slice of golden has a density around 17.7 to 17.eight grand/mL.

1
Purchase a gold-testing kit to become the acid you lot need for the test. Testing kits include various bottles of nitric acid for unlike types of gold. Some tests likewise include a flat rock called a touchstone you tin use to scratch off some of the gilded on your item. You may also see needles with samples of yellow and white gold to apply as a comparison to your item.^[17]
- Testing kits are bachelor online. Likewise, check with local jewelry stores. Most jewelers use this test for its accurateness.
2
Create a small scratch on the gold using a sharp tool. Choose an camouflaged location on the jewelry to make the scratch, such as underneath a squeeze or an inner band. Then, apply a abrupt tool such as a jewelry engraver to dig into the gold. Scratch until y'all get underneath the pinnacle layer of gilded. Expose a fresh layer of gold or any other metallic underneath it.^[eighteen]
- Nitric acrid tests require you to scratch your piece of gold. If the gold has personal value to you or y'all plan on keeping it, accept information technology to a professional jeweler instead of doing the exam yourself.
3
Add a drib 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 y'all're gear up, wait for the bottle of acid labeled for 18K gilt. After setting the gold in a stainless steel container, place a drop of the acid directly on the scratch you fabricated, and then lookout man for it to plow a shade of dark-green. If information technology turns dark-green, yous know right away your gilded is fake.^[19]
- Regular gilded does non react to the acrid, and then your particular might exist gold plated or a low-purity alloy of metals.
- A milk-colored reaction usually indicates gold-plated sterling silver. If the acrid turns gold, you accept gold-plated contumely.
4
Scratch the gold on a touchstone to test its purity. If you call back you might take real gold, rub it along the touchstone to create a streak of gold flakes. Add a drop of 12K, 14K, 18K, and 22K nitric acrid to different parts of the streak. Check back later on 20 to 40 seconds. Find the spot where the acid doesn't dissolve the golden to figure out what karat rating your detail is.^[20]
- The acids all increase in strength, and so the acid used for 22K is stronger than the 12K one. If the 18K acid dissolves the gilt just the 14K one doesn't, you know your detail is probably around 14K.

With a magnifying glass, look for a purity hallmark from the manufacturer on the jewelry particular. For example, if y'all own the purest gilded, you should see hallmark "999" or "24K" engravings somewhere on the jewelry item. With older jewelry as an exception, typically, if you practice non find a mark it may not be 18-carat golden. Suspicious marks and discolorations effectually the edges of the detail in question can also be telltale signs the gold is fake. An easy at-dwelling house test is to come across if the gold jewelry item sticks to a magnet. If the item sticks to the magnet, it may be fake or non 100% gold.

Most gold tests are imperfect, so you may demand 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 examination to protect your teeth.
When jewelers say that golden is 24K, they mean that the aureate is 99.9% pure with minimal traces of other metals. A piece of aureate that is 22K is 22 parts gold and 2 parts another metal.^[21]
In items that are less than 24K in quality, the other metals give the golden its hardness and color. Gilded on its own is very soft, so metals like silver and copper are added to make golden items more than durable.
Jewelry made with white gold, yellow gold, crimson gold, and rose gilded are all combinations of gold and other metals.
If yous ever need help determining whether gold is real, take your particular to a professional person jeweler or appraiser.

Nitric acid is strong and tin can burn your skin in addition to dissentious a valuable piece of aureate. If you lot're worried about this, you can do a dwelling test with vinegar, which is a milder acid, or you can let a professional jeweler or appraiser handle the nitric acid test.
