Chrysocolla is getting darker (black). Will it become black in a time or will it get its own gree/turquoise colour?

0 votes

Hi all, I buy some Chrysocolla beads from Alaska, that were looking like Turquoise. But now they become getting darker and darker, and some of them become black. Are they gonna get back their own color, and what makes this Mineral/Gemstone to become dark like that? What I have to do to prevent it getting darker?

Thank You for your help, much appreciated

Hi Hershel, Here are the pics from the necklace. They are from Alaska, and the chain was sold to me as a Turquoise. The other peaces i buy them recently. They all were nice light blue/green/turquoise color, and they start becoming darker and black. I bring them to one expert here, and he told me that they might not be Turquoise, and that might be Chrysocolla. Im not sure which one is. But as you can see at the pics, they start becoming darker and almost black. Some of the beads are completely black.

Thank you for your help !alt text Zack

Looks more like chrysocolla. I have never before heard of chrysocolla (nor turquoise) from Alaska, nor of chrysocolla (nor turquoise) that darkens on prolonged exposure.
