How to test your gold jewelry if it's real

Magnet Test
This test is most suitable for finding out if an item is pure gold or has a high percentage of gold. To carry out this test, the tester will have to use a high strength magnet and hold it close to the gold item. If the item does not get attracted to the magnet at all, then it is likely pure gold. If there is a slight attraction but not enough for the item to stick to the magnet, then the item is still gold but has a lower percentage of gold content than a pure gold item. If the item readily attaches to the magnet, that means it is not made of gold or only has a very low percentage of gold content. Do note that this isn't a foolproof test to determine if an item is made of gold; some counterfeit pieces are made from metals that are not magnetic in nature.

The Density Test
Gold has a higher density than a lot of other metals. Because of this, it is possible for the tester to carry out a density test on a gold item. This can be done by placing the gold item in a jug of water. Real gold should sink right to the bottom. If the item floats then it is most likely fake. However, just as with the magnet test, this isn't a very good confirmation test for a gold item as there are other metals which sink as well.

Acid Test
The acid test is best carried out on pieces of gold that the tester won't keep or sell for aesthetic value (so it's best to avoid using this to test gold jewelry). To carry out an acid test, the tester will need nitric acid, hydrochloric acid, or sulphuric acid, and a dropper. Nitric acid is the strongest and the most common acid used to test gold. Before doing this test, the tester should also buy and put on some protective rubber gloves and eyewear, as a safety measure.

Doing the test is quite simple; the tester just needs to drop one or two drops of acid onto the gold item, preferably in a hidden spot. If there is no reaction to the acid at all, it is highly likely that the tester is dealing with real pure gold. If there is a reaction, then the item is probably gold-plated or only contains a small quantity of gold.

If the tester wants to know the exact percentage of gold an item contains, then he or she can purchase a acid test kit that is specifically meant for gold. These test kits contain a testing stone and different concentrations and combinations of acid for different karat values of gold. The tester will need to scrape a bit of the gold item by rubbing the item on the testing stone, and afterwards use the different acids to figure out the gold content amount. For example, when tested using the acid for 14K gold, the item should not react if it is a 14K or higher gold piece. These test kits usually come with instructions, which the tester should read and carry out accordingly.
