You might have an older piece of jewelry that does not have a jewelry mark, which could make you wonder if the piece is counterfeit. You will want to conduct additional tests on the piece. All precious metals can be tested through the use of an acid test that will only harm fake materials. Genuine gold will stand up to your attempt to conduct a nitric acid test at home.
Make a tiny mark on the piece of gold to penetrate the surface.
Drop a small amount of liquid nitric acid maganin kiba na hausa that scratch and wait for a chemical reaction. Fake gold will immediately turn green where the acid is. Gold-over-sterling silver will become milky in appearance. Gold will not react to the nitric acid. The desired result is a clear drop of liquid that does not change color. Genuine gold will not attract a magnet. The magnetic test is the most convenient and portable test for genuine gold, since the magnet can be carried around in your pocket.
Imitation gold and other alloys will attract the magnet. Coins can appear to be gold, when in fact the surface is simply gold in appearance.As a native Californian, artist, journalist and published author, Laurie Brenner began writing professionally in She has written for newspapers, magazines, online publications and sites.

In gemstones, carat refers to the weight of the cut stone, but in gold, karat refers to the gold's purity or quantity. Solid gold consists of 24 karats, but, in jewelry, you'll more than likely see gold rated at 22K, 18K, 14K, 10K or even 6K.
Each karat determines how much gold is in the item. You can test for real gold at home by using one of several methods: magnets, nitric acid, float and rust test and the stamp test, or look for skin discoloration when wearing gold jewelry. The magnet test is one of the easiest tests to perform, but to do it, you need a stronger-than-normal magnet, available at most hardware or home improvement stores.
Run the magnet over the gold jewelry or item. If the gold is attracted to the magnet, it is not real gold. Jewelry clasps or catches are not made of real gold; if one of these is the only part of your jewelry item that is attracted to the magnet, your gold is real. Jewelry from reputable jewelers contains gold stamps or identifying stamps on them.
You'll need a magnifying glass to locate them.
5 Easy Tests You Can Do at Home to Tell If Your Gold Jewelry Is Fake (With Pictures)
The stamp should include karat markings or a jeweler's mark; sometimes, the jeweler marks the percentage of the gold rather than the karat. For example, 22K gold would read. Real gold never rusts; if you notice rust on your gold item, it's fake gold.
Set your gold item in a clear water-filled glass. Real gold is heavy, so it should drop to the bottom; if it floats, it's fake.
Unless you have an allergic reaction to gold, if your skin changes color — black or greenfor example — it's a good indication that the gold is fake.

If it turns a milky white, it's gold-covered sterling silver.
Real gold creates no reaction. Nitric acid is caustic and hazardous to inhale. If you pan for gold as a hobby, it's easy to mistake pyrite for real gold. Called fool's gold for a reason, pyrite has some of the characteristics of real gold, except when you scratch it with a fingernail or pointed item, it falls apart.

Gold is not magnetic. On the other hand, imitation gold and other alloys are, so they will attract a magnet. Steer clear of the clasp on your piece when testing with a magnet to prevent any confusion. If you do perform this task, you should wear a mask since this can be a potential health hazard if not handled properly.
Many jewelers use the nitric acid method to determine the authenticity of gold jewelry. Drop a small amount of nitric acid onto the piece and look for a reaction.
If the jewelry is gold plated, you may have to make a tiny scratch in the metal to allow the acid to saturate the underlying metal. If the acid produces a green reaction, the jewelry in question is probably a base metal or gold plated. A white, milky reaction is most likely indicative of gold plating over sterling silver. What you really want to see is no reaction at all—real gold should not react when it comes in contact with nitric acid.

Real gold jewelry is made of a solid gold alloy, whose gold content is above a certain threshold. In the United States, for example, pieces containing less than What people usually refer to as fake gold is jewelry that is made of another metal such as nickel, copper, silver, etc. Then, nitric acid of varying concentrations is applied to the mark to see whether it will be dissolved.
Depending on the concentration of the acid that causes the mark to be dissolved, the purity of the alloy can be inferred. This test can be performed at the jewelry store by a jeweler or at home, by using a gold testing kit and following the instructions that come with it.
You should keep in mind that the scratch should be deep enough so that you can get to the material beyond the top layer of the jewelry. Otherwise, if the piece is gold plated or gold filled, a light scratch might only rub off the top gold layer, and the test will show that what you have is indeed gold.
Karat markings on jewelry indicate its purity. European jewelry is often marked with parts-per-thousand markings instead of karat hallmarks. It is important to look for any markings next to the karat or purity number that might indicate that the jewelry is gold plated or gold filled. Markings are not necessarily reliablethough. Fake gold that is just plated could be missing any letters identifying it as such.

So, if you see any scratches under which the metal below is visible or discolored spots where the top layer has been rubbed offthis is a sign that the jewelry is just covered with gold and note made entirely of it. An indication that a piece of jewelry might be gold plated is if its color is the intense yellow that is characteristic of pure gold.
Gold-plated items are sometimes covered with a layer of karat gold. The methods listed below are of limited usefulnessas they are more unreliable than the tests described above. This is a popular test that is based on the fact that gold is soft, so if you bite it, your teeth should leave marks on it. First, lower-karat gold alloys such as 10K or 14K gold are relatively hard because of the higher content of non-gold metals in it, and these alloys would not pass this test despite being considered real gold.
Second, there are other soft metals that can pass the bite test and that can be covered with gold to make a fake gold piece. The magnet test is another popular test. The reasoning behind it that fake gold should be attracted by a magnet while real gold should not. It is true that pure gold is not magnetic. However, there are a number of other metals that are also not magnetic and that can be used to make a gold-plated jewelry piece.

Fake gold jewelry is made of other metals that are much affordable than gold, which includes silver, nickel and copper. And they are just often plated with gold to make them look like real ones. These tests are easy and can be done right at the comforts of your own home. Nitric Acid Test. Nitric acid tests are used for different kinds of precious metals.
Nitric acid is known to cause harm in fake jewelries while not affecting gold in any way. To carry out this test, make a very tiny mark or an invisible small scratch on the jewelry and drop a small amount of nitric acid into it. If the spot turns green, it is definitely a fake gold. If it turns into a milky white color, you've got yourself sterling silver. If there is no discoloration or any reaction in the spot, the jewelry is a genuine gold. Float or Density Test. This test is the one of the easiest ones to carry out if you want to check if you have an authentic piece of gold jewelry.
Gold has higher density than most metals, which means it should sink right in water. What you need for this test is a cup or jug of water.
Real gold jewelry will definitely sink, while fake jewelry will float right at the surface of the water. Magnet Test. The magnet test is suitable for testing a jewelry, which you think has high percentage of gold.
To do this test, you need a high-strength magnet and not just any ordinary magnet out there. Place it close to the jewelry and see if there is any reaction. If the jewelry gets attracted to the magnet, then it is a fake gold. If there is very little attraction but the jewelry does not stick to the magnet, you have jewelry that has low percentage of gold.
If there is no attraction at all, then it is most likely real gold.
