Chrysocolla is found in colors that range from light green to deep blue and owes its color to the presence of copper. The presence of other impurities causes vibrant patterns within the stone appearing as spots, streaks, veins, and other patterns. These patches, streaks, or veins can be yellow, red, black, or brown.
Does chrysocolla have a crystal structure?
Chrysocolla is perhaps more appropriately a mineraloid than a true mineral. Most of the time it is amorphous meaning that it does not have a coherent crystalline structure. However, at higher temperatures, it does demonstrate a distorted crystal structure that seems to be composed of Si4 O10 sheets.
What is chrysocolla worth?
It is often known as “chrysocolla chalcedony” or “gem silica chrysocolla.”. Gem silica is the most valuable variety of chalcedony , with quality cut gemstones selling for over $100 per carat.

How is chrysocolla made?
Chrysocolla, a silicate mineral, hydrated copper silicate, CuSiO 3 ·2H 2 O, formed as a decomposition product of copper minerals in most copper mines, especially in arid regions. It occurs as crusts or masses in the upper parts of copper ore veins where the copper minerals have been altered by water containing dissolved silica.
