Chrysocolla-bearing copper mineral specimen

Chrysocolla, hydrated copper aluminosilicate (approximately (Cu,Al)₂H₂Si₂O₅(OH)₄·nH₂O), possibly mixed with malachite

AI-generated identification · may be incorrect

Blue-green to green, typically dull to waxy or glassy; Mohs hardness 2–4, no consistent cleavage, amorphous to microcrystalline structure, and specific gravity about 1.9–2.4. The blurred image suggests a polished or naturally rounded fragment with dark green matrix.

Physical properties

Formation & geological history

Forms as a secondary copper mineral in the oxidized zones of copper deposits, commonly alongside malachite, azurite, quartz, and limonite. It is generally geologically young relative to its host rock, forming through groundwater alteration near the surface.

Uses & applications

Used as a decorative stone, cabochon, bead, and collector specimen; softer material is often stabilized with resin. It has little industrial importance compared with copper ores.

Geological facts

Its vivid color comes from copper and can resemble turquoise or malachite. Chrysocolla is commonly porous and may be confused with dyed howlite or glass.

Field identification & locations

Look for irregular blue-green color, low hardness, and association with black, brown, or green copper-mineral matrix; it may scratch with a knife. Common localities include Arizona, Nevada, Chile, Peru, the Democratic Republic of Congo, and Australia.
