Chrysocolla is attractive blue-green that provides a unique color
to the mineral world. Chyrsocolla 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. Chrysocolla forms in the oxidation zones of copper
rich ore bodies.
Our chrysocolla is "agatized" in chalcedony quartz and it is the
quartz that provides the stone with its polish and durability.
Our chrysocolla can have a turquoise color.
