This article will give you the tools and guidance on how to check your gold jewelry purity and give you a caring advice. If you are not sure about your gold jewelry purity you can check it with a simple Gold Test Kit. How to do it?.. There are simple gold test Kits that include test stones, set of gold test needles and 10kt, 14kt, and 18kt acids. These acids include Hydrochloric Acid & Nitric Acid combined together because there is no acid that can consume the gold by itself. The test stone (Touchstone) is usually black silicone stone 20/40 mm. Test Process… First we need to check if there is any “gold purity mark” on the jewelry. We choose unimportant part on the jewelry and polish it on the test stone until we get an extended stain on the test stone. Next to this stain we make another stain on the test stone with the gold test needles. There is another option, if we don’t have gold test needles we can use another piece of gold on which we insure the purity level and then according to that test we will test the first piece of gold. On the stains we created we will drip acid with the purity level we want to check. If the stains are gone- that means the acid consumed it! So the gold purity level is lower than the acid purity level! If we still see the stain- that means the acid didn’t consume the gold so the gold purity level is higher than the acid purity level we dripped on!
