4.2" Polished Blue River Chrysocolla Slice - Arizona
This is a beautiful polished slice of "Blue River Chrysocolla" which comes from a newly discovered deposit in Arizona. The chrysocolla is a vibrant blue color and filled in around the brecciated host rock. It has been cut flat on both sides and polished to a glossy finish on one. It comes with an acrylic display stand.
The chrysocolla is associated with a green mineral, however this mineral is unidentified. While it's likely malachite, it's possible that it could be one of the many secondary copper based minerals that commonly form in association with chrysocolla.

Chrysocolla is a basic copper silicate that typically forms as a pseudomorph following other copper based minerals. The chemical formula is considered undetermined due to the varying substitutions of elements and water content in its chemical structure. However, there is a form of chrysocolla with an identifiable chemical formula of Cu2H2Si2O5(OH)4 that can be found in microcrystals.
Regularly, chrysocolla will form as botryoidal lumps and spheres, rarely forming visible crystals. It can also form in both solid and fibrous veins, over fibrous minerals, and in crusts. Known for its sharp and vibrant coloring, chrysocolla can display a wide variety of colors such as bluish-green, bright green, light blue, to even sometimes multicolored specimens depending on the atmosphere present during formation.
