Simple way to check the purity of gold. Place your piece of gold in a stainless steel container . Drop a very small amount of nitrate acid onto the gold. Watch for any change reaction to the acid. Green reaction means gold plated brass, milk colored reaction means gold plated silver, no reaction means real gold.

well, there are a few proven methods with which you can check the purity of gold at home. Some of them are -
1. If you have gold coin, measuring the weight can be a better way to check for purity.
2. Use small sized magnet to check if it contains impurities. Gold in real form is non magnetic.
3. Acid testing is one of the best ways to check the purity of gold. You can buy the acid test kits available in the market. Please note that the tests should be conducted only on a sample as it will discolor your sample.

Gold is a precious metal. It is not advisable to attempt to check purity of gold at home and generally it will not be possible to get any accurate result. Pure gold i.e. above 99.95% gold is yellow in color, but copper is alloyed with gold to make it hard enough to make durable ornaments. Generally 22 carat i.e. 95.83% to 18 carat i.e. 79.16% pure gold is used for making ornaments. Alloying with copper changes its color to reddish yellow in appearance. In traditional methods, the jewelers used to attempt to evaluate the purity of gold by scratching it on a black color stone known as 'touch stone' and assess the percentage of copper mixed. Since the common men were unable to use such methods most of them used to be cheated by the jewelers.
The best method to know the purity of the gold is to take it to a reputed jewelry shop where caratometer is installed and get it evaluated. A caratometer uses X-rays to give an exact reading of the purity of gold.
