Gemstone of the Week: Chrysocolla
Chrysocolla is a blue to blue-greenstone often mistaken for Turquoise. There are a couple different varieties of Chrysocolla. One, known as Eliat stone, is a combination of Chrysocolla, Turquoise, Azurite, and Malachite. There is also a variety called Parrot Wing which is Chrysocolla and Jasper. It gets its beautiful colour because it is a copper based stone.
There is another variety of Chrysocolla called Chrysocolla Quartz which is a Chalcedony with some Chrysocolla content and sells for about $10-$30 a carat. There is also Chrysocolla gem Silica wich is much more valuable and is an even-coloured, very translucent Chrysocolla Quartz selling for $50-$300 a carat. (Some of the best can be found in Arizona.)Informational Sources:
