2.7" Sparkling Quartz on Chrysocolla & Cobaltoan Dolomite - DR Congo
This specimen includes a rock matrix partially covered in a thin layer of chrysocolla, encrusted in a layer of sparkling druzy quartz. The quartz crystals are translucent, allowing for the underlying light blue chrysocolla to be seen. In addition, there are small aggregations of malachite present, some of which are covered in druzy quartz. The chrysocolla, malachite and quartz all sit on a bed of cobalt-bearing dolomite. This material was collected from the Tenke-Fungurume area of Lualaba, Democratic Republic of the Congo.
Comes with an acrylic display stand.

About 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.
