Misc Prop: Chrysocolla is rarely found in a pure state, but rather in combination with many other minerals including; quartz, turquoise, and malachite. Being a hydrated mineral it has wide density range and can be damaged by heat.

It is beautiful sky blue color and can easily be confused with some varieties of turquoise. It is usually cut in cabochons as it is normally translucent at best. It is often found in combination minerals with copper content.

Below are some examples of chrysocolla rough but I currently have no cut stones.
