To perform this test to check if gold isreal, make a light, tiny scratch on the item using a smallnail file. Choose a spot that is not noticeable if possible.Use a dropper to apply a small drop of nitric acid to the scratch.If there is no reaction, then the piece is probably madefrom real gold.
Additionally, how does gold get its color? The color of gold jewelry can beattributed to the addition of different amounts of several metals(such as copper, silver, zinc, and so on). When indium or galliumis added to gold, a blue color can result. Thecause of color in these intermetallics is differentthan that of yellow gold.
