Physical properties
Hardness of 7 on the Mohs scale. Displays bright cyan to turquoise-blue coloration with vitreous to waxy luster and cryptocrystalline structure.
Formation & geological history
Formed through secondary hydrothermal alteration of copper deposits, where silica-rich fluids permeate chrysocolla-bearing rocks.
Uses & applications
Highly prized in lapidary arts for high-end cabochons, fine jewelry, and collector display specimens.
Geological facts
It is one of the rarest and most valuable forms of chalcedony due to the combination of rich copper coloration and quartz durability.
Field identification & locations
Identified by its intense blue color, conchoidal fracture, and high hardness relative to pure chrysocolla. Found primarily in copper-mining regions like Arizona.
