Advanced Fake Gold Detection Techniques

How To Tell If Gold Is Real – With A Magnet Test
  • Melting and Sampling spectrum detection: This is a more vigorous test, but is worth the effort and slight cost. Melting and sampling spectrum detection takes advantage of a thermo-analytical technique known as Differential Scanning Calorimetry. A sample of the gold to be analyzed is placed in a Differential Scanning Calorimeter alongside a reference gold sample. The same temperature intensity is applied both to the sample and the reference gold material. The difference in the amount of heat needed to increase the temperature of the sample as compared to the reference is recorded. It is this heat difference that helps to analyze how different or similar a piece of gold is from the original. Fake gold is easily detected with this technique as it will have widely varying heat properties from real gold.
  • Metallographic Analysis: This technique has wide usage and can be found in literature where it has been used for detection of fake gold and silver coins. The results can similarly be applied for the detection of fake gold in jewelry production. Metallographic analysis applies the principles of metallography in the identification of fake gold. This often involves microscopy. Optical microscopy or scanning electron microscopy with energy-dispersive x-ray analysis are two types of microscopy often employed. Since the properties of real gold are already known to experts. A comparison of the sample properties with the expected ones will reveal the originality or otherwise.
  • 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.

    The Basic Properties Of Gold

    Gold is found in nature as a pure metal . It has a distinct yellow color its resistant to chemicals its a good conductor of electricity and heat its not magnetic and it doesnt rust. Gold is highly dense, a property thats crucial for gold panning, and it has ayellow streak, a very simple feature that distinguishes it from fakes, like pyrite.

    Another important property of gold is its low hardness.Pure golditself is actuallyvery soft. Because of this, jewelry isnt made with pure gold, but rather an alloy . The metals that go into the gold alloys significantly influence the properties of the final alloy, specificallyits hardness and color.

    Hallmarks show that an assay test has been carried out on the gold object to confirm its karat rating. The reliability of the hallmark depends upon the country of origin. State-controlled assay offices imprint a mark onto the gold showing the year and place of assay together with the percentage of gold found, or the karat rating. The hallmark is very small so you may need a magnifying glass or jeweler’s loupe to see it clearly.

    Testing Gold With Household Items

    How to know if your gold is real or costume jewelry
  • 1Drop 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 youd like to test. The water temperature you use doesnt 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.XResearch source
  • Real gold also doesnt rust or tarnish when wet, so if you see a discoloration, you probably have plated gold.
  • 2Put 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 wont change color, but fake gold will.XResearch source
  • 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.
  • 3Find 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.XResearch source
  • For example, a silver coloring might indicate silver or titanium. A red coloring could mean copper or brass.

    What The Gold Stamp Means

    If you do find a number marking on your gold item, heres how to read it. There are two different numeric scales used in hallmarking. The numbers 1 to 999 or 0K to 24K may be used to show the amount of gold in the item. The numbered system is European and the K scale the U.S. ranking. For the European system, the number can be transferred easily to a percentage, so 200 is 20% gold and 500 is 50% gold. For the U.S. system, 24K is 99.9% pure gold, 18K is 75% gold, 14K is 58.5% gold and 10K is 41.7% gold. Anything less than 10K is considered fake.

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

    Fact checked by Kidadl Team

    Gold has been around for ages, and it is considered one of the most precious metals.

    For thousands of years, human civilizations have made use of gold in their architecture, currency , art, ornamental objects, and gold jewelry. Gold across the world is renowned for its association with beauty, power, and wealth. Its property of malleability and resistance to tarnishing is just the cherry on the top.

    In the history of gold, it is considered to be the harbinger of prosperity and development in human societies. Gold was the first metal we discovered. It was found in its natural state, in the form of shining nuggets, on the bottom of a river bed. In those days, gold was found abundantly all across the world in river streams. If we go back millennia when gold wasn’t treated as money or commodity, many Indians, Egyptians, Chinese and other cultures went to war in their quest for gold, because it had intrinsic value like no other.

    It was during 700 B.C when gold was first treated as money by Lydian merchants who just stamped lumps of mixed gold known as electrum. But how do you tell if a piece of gold jewelry is real gold or gold plated? And in the worst circumstances, how can you tell if gold is fake? In this article, we have discussed the difference between pure gold, fake gold, and plated gold and the steps to testing gold. Read on so you can easily test gold at home!

    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.

    Look For A Letter Mark

    If the has the letters GP, GF, or GEP stamped on it, these indicate that it is not made of real gold. GP means it is gold plated, GF means it is gold filled, and GEP means it is gold electroplate. That is, the jewelry is made of some other metal with a thin layer of gold on top. While this gold plating may be real, it is an insufficient amount of gold for the item to be considered true gold.

    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.

    Another Word Of Caution

    This article only lists five of the easiest methods to test your gold.
