I thought about id’ing it with a spectrometer, my GIA text book says that that test is inconclusive as it varies so much. I was wondering about an electrical test, such as a diamond tester. Copper is electrically conductive, that’s what a diamond tester uses to test diamonds and moissanite. Anybody ever heard of something like that?
Also wouldn’t I use the IGS system for a positive ID? They have cert’s available with photos for $120.00 to members. Or do you think a GIA certificate is better?
