The Size And Weight Test

How to Tell Real Gold from Fake

This test works well on coins and bars. You can

  • Compare a piece of gold you want to test with one that is already known to be real
  • Use a set of calipers and a jewelers scale or use a Fisch Tester

Gold is denser than most other metals. If you have a piece that looks too large for its weight or feels too light for its size, then you probably have fake gold.

Bullion coins are actual coins made from precious metals, including gold, silver, palladium, or platinum. They serve as collectibles, investments, or as a hedge against inflation.

How To Test Gold Jewelry

Jewelers make an impression in each gold piece of jewelry designed and crafted from genuine molten gold bullion. On necklaces and bracelets, this stamp is on, or near, the clasp. Rings have a stamp somewhere on the inside surface. A jewelers loupe is sometimes required to see the tiny stamp placed on fine gold jewelry. The jewelry stamp will include the karat, also called the purity, of the piece, such as 14K or 24K. Close to this stamp is the manufacturers stamp, which further clarifies genuine gold jewelry.

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.

Test : The Float Test

For jewelry youve got at home you can always do a quick float test to see if it is real or fake! All you need is a cup of water.

Drop the jewelry in the water and see what happens. Real gold will sink, as it is a heavy metal. If the jewelry floats, more than likely, it is not real gold.

If it doesnt immediately sink or does not sink all the way, you may have jewelry that simply has less real gold than you thought it did.

How To Tell If Gold Is Real / How To Test Gold At Home

Counterfeit gold is common, so its helpful to understand some of the properties of this precious metal to determine whether your piece is in fact real gold. The first is that gold is not magnetic, so if you notice that your jewelry or bar jumps toward a magnetic surface, it is not real. Gold also doesnt corrode or tarnish, unlike aluminum, copper, silver, and brass. Therefore, if you notice any oxidation on your gold piece, it is not completely gold.

Another simple method is the float test. Drop your piece into a glass of water. If it sinks quickly, its more likely to be real gold since gold has a higher density than other metals. However, some metals that can pass for gold are also heavy, so this is a good test to try in conjunction with others.

The scratch test is a great way to determine if your jewelry is real gold, but it can damage your piece, so be careful. To perform this test, rub your gold against a piece of unglazed ceramic or porcelain. If the mark left is gold-colored, your piece is very likely real gold. If the mark is black, the piece is not real.

How Do You Test Gold With Vinegar

One way you could test if your gold is pure or not is by using vinegar. There are many ways that you could use this method, and the good thing about it is that it can no way harm your jewelry unless it is not pure gold. All you need to do is get the jewelry item you want to test and white vinegar. Place your jewelry on a table or hold it in your hand, pour some white vinegar on the metal directly if the metal of the jewelry changes its color, it is not pure gold and if it keeps shining then you have real gold in your hand.

You can also fill a cup or glass with white vinegar, and drop your gold in it, let it soak for 5-8 minutes, take it out and rinse with water. If the metal has changed its color even slightly, then the gold is not pure but if it keeps shining, then the gold is pure.

Look For Bluish Or Greenish Tint On Your Skin

This test is simple: It involves holding a piece of gold jewelry between your hands for a couple of minutes. The perspiration from your hands will either react with the metal and change the color of your skin or leave it unaffected. When real gold is in direct contact with your skin there is no discoloration. If the gold is fake it will cause your skin to turn black, blue, or green at the contact points.

One exception to this procedure occurs if you test gold on your skin while wearing a liquid foundation. When gold touches the makeup it will turn your skin black at the points of contact. Removing all makeup before testing makes this test more reliable.

Alternatively, makeup can also be used to test for gold authenticity. Put on a liquid foundation and add powder over it. Once the makeup has dried, press the piece of jewelry against your skin and then run it lightly over your skin where you have the makeup. If the jewelry leaves a black track on the makeup, you probably have real gold.

Gold is extremely nonreactive, so real gold jewelry will never discolor your skin. But using the makeup test is a unique way to also check if its real.

If there are discolorations in gold jewelry it means you have an alloy where there are other metals mixed in.

What Is Fool’s Gold

How to Know if Your Jewelry is Real Gold or Plated

“Fool’s gold” is a common nickname for pyrite. Pyrite received that nickname because it is worth virtually nothing, but has an appearance that “fools” people into believing that it is gold. With a little practice, there are many easy tests that anyone can use to quickly tell the difference between pyrite and gold.

The nickname “fool’s gold” has long been used by gold buyers and prospectors, who were amused by excited people who thought they had found gold. These people did not know how to tell the difference between pyrite and gold, and their ignorance caused them to look foolish.

Crystalline Gold: A specimen of native gold from Pontes e Lacerda, Mato Grosso, Brazil, approximately 3.5 centimeters tall. This specimen is visually appealing and displays the crystalline habit of gold. The value of this specimen to collectors of crystalline gold would be many times the value of its contained gold. Destructive tests should not be done on specimens of gold that display a crystalline habit or specimens of no trivial size that have an attractive appearance. This photo was taken by Carlin Green of the United States Geological Survey.

Take A Close Look At The Metal

There are other visual clues that can help you determine whether a piece of jewelry is real gold.

Gold-plated pieces are often marked with GP, GF or GEP . Although the plating is gold, the core of the item is base metal and wouldnt be considered real gold.

Another thing to look out for is discoloration on any part of the metal. Gold is non-reactive, so wont generally discolor over time.

A good place to look for color changes is at points of wear. These are usually around the edges of rings, pendants or coins, or on the clasps of chains. If the item has been gold plated, this is where the gold will rub away quickest, exposing the different colored metal underneath.

Test It With Your Skin

Perhaps the easiest method on this list, the skin test measures the level of impurity in a gold item by merely holding the object in your hand. Just make sure the area of skin youre testing against is clean of anything that might interfere with the reaction, such as lotion. Because of real golds properties, it shouldnt result in any discoloration or staining of your skin the way brass might leave a greenish tint.

To run the test, hold the item in your hand for a few minutes. Base metals will react to the sweat on your skin and create a chemical reaction. As a result, your skin should turn green or black depending on the metal or alloy its reacting to. If there are no marks on your hand, then you can trust that the item in question is real gold.

Liquid foundation presents an alternative way to test whether something is gold. After applying a thin layer to your skin and letting it dry, gently rub the gold against it. If that results in a line or black streak, then the gold is likely genuine.

How To Tell If Gold Is Real: Bonus Tests

We don’t highly recommend these tests because they don’t give conclusive results. However, they cost nothing and in no way damage your precious gold. So, why not give them a try?

a) The Sound Test

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.

b) The Bite Test

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.

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.

Q How To Differentiate Between Gold Or Gold Plated Items

5 Main Differences Between Real and Fake Gold: Do You Know ...

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.

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.

Gold’s radiation is different from any other metal, so it will be easy to identify the authenticity of your item.

What Counts As Gold

To begin with, lets define what were talking about here. Most, if not all, authentic gold jewelry isnt actually made of pure gold.

Thats because gold is a very soft metal. If it were used in its pure form, the jewelry would bend out of shape, or even break, all too easily.

To deal with that problem, gold is mixed with other metals. The type of metals and how much of them is used depends on the color and karat rating of the gold.

In its natural form, most gold is the wonderful warm yellow color we know and love. But youll also see rose gold and white gold used in jewelry and other objects.

Rose gold is a mixture of gold and copper. It usually also contains some silver. The result is a beautiful pink metal.

White gold is another gold alloy. Here, gold is mixed with white metals, usually palladium, silver and nickel. White gold jewelry is usually then plated in rhodium to give it a distinctive high shine.

Both rose and white gold are considered to be real gold. The amount of pure gold they contain varies, depending on their karat rating. More on that in a moment.

As weve seen, yellow gold is also mixed with other metals to make it strong enough to be used in jewelry. Whether your gold is yellow, white or rose, the amount of pure gold it contains is indicated by its karat rating.

Other common karat ratings are 10, 14 and 22-karat. And older jewelry, from the Victorian or Edwardian eras, often used 15-karat gold.

What Are The Properties Of Gold You Should Know

How to know if your gold is real or costume jewelry

Remember that gold has been a precious, highly-coveted metal for thousands of years, not just because it is beautiful, but because it has distinctive properties, including:

  • Oxidation resistance: It wont tarnish or rust like other metals do, including silver, aluminum, brass, and more.
  • Malleable and ductile: Its a soft metal and can be molded into thin wires for circuits, alloys, fillings, and more. Its also a great conductor of electricity since it isnt as susceptible to rust or corrosion.
  • Not magnetic: Unlike other metals, gold is not even slightly magnetic.
  • Low dissolvability: Gold can only be dissolved with a concentrated acid mixture called nitro-hydrochloric acid.

How To Tell If Gold Is Real: The Secret Weapon: Acid Tests

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.

a) Testing with Vinegar

Gold is almost inert, so vinegar’s acidic element cannot change its color or properties. Use white vinegar since it’s the most acidic of all types.

Just add a couple of drops of vinegar to the jewelry piece and see if the color changes. It’s 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.

b) Testing Gold with Nitric Acid

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 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.

How To Tell If Gold Is Real Or Fake

What makes gold real or fake? Most standards around the world identify anything with less than 41.7% or 10 karats of gold as fake. The most reliable way to identify whether your item is real gold, or not, is to have it appraised by a certified jeweler. However, before you take your item in for a professional appraisal, there are some simple methods for discovering whether your gold item is real or fake.
