It is not a accurate test, but very close. The test is straight forward and the overall goal is to figure out the gold purity. The first step is to scratch a sample of the metal onto a testing stone like the one below. One thing to look for is the color of the scratch mark. If you have yellow gold, the mark should be yellow as well.
