Description

2.75ct Gem Silica from the Ray Mine in Arizona.

Also known as Chrysocolla/Chalcedony, Gem Silica’s color comes from Copper.  It’s mined in only a few Copper Mining locations worldwide, with the Arizona locations being the most sought-after.  Durability on these gems is quite good (7 on the Moh’s hardness scale, without cleavage), making them suitable for daily-wear ringstones!
