Hi, i know this is an old topic but i was curious about gold jewelry TID Numbers on my x-terra 705 and came up with the below results. Each reading was with a different piece of jewelry including mostly rings, pendants, bracelets and necklaces.
375 9kt - 4, 6, 8, 12, 14, 20
500 12kt - 10
583 or 585 14kt - 10, 28
750 18kt - 4
As you can see the numbers aren't very consistent with the Kt. I know the shape and size play a role but most things were the size of a ring. Could anyone tell me if they have found the same thing??
Cheers
Corey
