What do I test and authenticate?
I can identify and test precious gems like diamonds, sapphires, rubies and emeralds from simulants and gold & silver jewelry from faux metals. I am trained to recognize confederate & U.S. paper money, coins and art mediums like paintings, etchings and hot & cold cast mediums from replicas. For authentication, grading or anything else, please look below.
