1" Chalcedony on Fibrous Blue Shattuckite - Namibia
This is a beautiful, 1" wide formation of light blue to dark blue, botryoidal (shape) shattuckite that's encrusted in chalcedony, collected from Namibia. It has been mounted to an acrylic display base with mineral tack.
Shattuckite is an scarce copper mineral that is highly regarded for its vivid blue color. It is named after the Shattuck Mine in Bisbee, Arizona, where this mineral was first discovered. It crystallizes in the orthorhombic – dipyramidal crystal system and usually occurs in a granular massive form and also as fibrous acicular crystals.
