Message:: [QUOTE="J Dagger, post: 3474777, member: 10944"]Thanks Holly, I read a different discussion, on a different metal detecting site but didn’t see this one. So here’s a question; has anyone ever seen verdigris on something proven to be “solid” low karat gold? I don’t have experience with gold below 10k personally. However when it comes to silver I’ve never seen verdigris on .999, .950, or .925 silver. I have seen verdigris on lower fineness silver like .830, .800, and .750. Obviously this is due to the higher copper content. Holly’s link references 8k and the ring in question appears to have some corrosion or verdigris. Seeing that the copper/base metal content is much higher on low karat gold, is it possible for verdigris to form on it? On higher karat gold you can literally pull it out of the ground after decades or centuries being buried and it will usually shine and be intact just like the day it was lost or buried. I found a piece mourning jewelry I believe was at least 14k, it not higher and was probably lost well over 100 years ago. It was still perfect looking. So, is it possible for low karat gold to have verdigris?[/QUOTE]
