Chrysocolla
Chrysocolla
Wise speech flows from a quiet heart.
Chrysocolla is a hydrous copper silicate with vivid turquoise to blue-green color that comes from its copper content. It's soft, ranking 2 to 4 on the Mohs scale, and porous, which is why it's frequently stabilized with resin or naturally intergrown with harder minerals like quartz or malachite. Chrysocolla-in-quartz, sometimes called Gem Silica or Gem Chrysocolla, is the hardest and most durable form. The bright blue-green color makes it widely imitated by dyed chalcedony in the commercial market.
