Hi I was Mding in a park and found part of a necklace, about 7 inches long, it says 18k on the clasp and it has a security clip on it,, heres the problem. It is tarnished,,,if you scrape it with a knive blade its nice and gold colored, the weight is right but I thought gold didn't tarnish? How do I test it to see if it is gold??HH George
