This is most common in forged coins that look like gold. If the specimen is somewhat magnetic but does not cling to the magnet, it has been glided with other minerals. Therefore, the gold will never be attracted to a magnet if it is pure. Gold metal does not contain any iron, thus, non-ferrous. To attract the magnet, the metal has to have a small percentage of gold or entirely not made from gold. If the specimen is attracted to the magnet, then it is an alloy of gold or fake gold. The magnet should then be placed close to the gold specimen. For this test, you need a magnet with very high strength and a gold specimen. This method is one of the most suitable gold tests, especially at home.

It is recommended that you remove powder and or foundation from your skin before carrying out the test. If you do this test on the part of your skin that has been applied with powder or foundation, genuine gold will leave a black smudge. Nevertheless, wearing plated or fake gold jewelry, or handling fake gold bars can stain your skin. Genuine gold does not tint your skin lest you are allergic. This is due to your skin reacting with other amalgam metals and not gold. Your skin will then have a green or black color. If it is fake or plated gold, then the sweat on your palm will produce a chemical reaction with the gold metal. Hold your old object in your palm for some minutes. Conversely, this method is not 100% perfect as gold that contains extra heavy minerals will make the gold sink.Īlso, when placed in water, gold does not discolor or rust. Therefore, if your gold floats or lingers around the bottom part of the bowl, it is fake gold or has been gilded. This is because genuine gold is very dense. If the gold is genuine, it will sink to the bottom-most part of the bowl containing water. You only need to drop the specimen in the water. It requires water and the gold specimen that is being tested. It is one of the primary tests done on gold. The color of the produced powder of the tested mineral is referred to as its streak. This procedure can create a small quantity of pounded mineral on the exterior of the plate. The streak test is conducted by scratching a sample of the mineral across a section of unglazed ceramic recognized as a streak plate. A mineral’s color is an essential property that is used to recognize the mineral being tested. The streak test is another method that is used to determine the color of a mineral. Copper’s Mohs rigidity is 3 therefore, it is harder compared to real gold. For instance, fake gold can scrape a surface made of copper, while real gold cannot scrape a surface made of copper. Rigidityįake gold has got a Mohs hardness of 6.5 or 6, while real gold has got a Mohs rigidity of 2.5. Real gold flakes can be cut using a sharp knife, while fake gold cannot be cut. Gold is a soft metal, and therefore, to contest its softness, it must amalgam with other metals like platinum, copper, silver, or nickel. Pieces of fake gold cannot withstand this type of pressure and will break. A small bit of gold can be twisted or dent with force from a sharp piece of wood or a pin and can be as thin as paper. After carrying out this test, make sure to dispose of the acid used. You should also consider doing this acid test only on the specimen that you will not be bothered by if they get destroyed or scraped, and any objects that cannot be sold for artistic value. This will elude any preventable actions and expenses. You can only carry out this test if your specimen was recognized as non-magnetic. The original gold materials will not be harmed or scraped by acids.

Many acids may damage or cause harm to artificial materials. They are discussed below: The Caustic methods 1. The two main ways to identify whether gold flakes are real or fake are the caustic methods and non-caustic methods. Some tests can be used to tell whether gold flakes are real or fake. It is one of the most treasured metals on planet earth. Even in the ancient times, gold was valued above currency, same as it is right now.
