[1] Acid test The acid test helps to identify the true gold from the counterfeit. This test can be performed using a set of test instruments consisting of a set of acidic solutions, as well as a gold test, a stone used to determine the value of gold. Conscious of different solutions according to the carat to be examined, is scratched the piece of gold to
be examined by him leaving behind an impact on the stone, and then scratched another piece of gold of the same caliber for the first piece of gold, and put the acid solution for the carat on both scratches, and then make a comparison between [2] Buoyancy test A glass of water can be used to determine the purity of a piece of gold.

make an electrical circuit between the probe and the gold piece, and then test the electrical conductivity of that piece, and this property helps to test whether the piece of gold In fact, in addition to testing its purity, these devices are fairly accurate when used correctly, so it is advisable to clean them off the gel completely between applications.
