Chrysocolla-bearing copper ore

Primarily chrysocolla, a hydrated copper silicate (approx. Cu₂−xAlx(H₂−xSi₂O₅)(OH)₄·nH₂O); exact identification is uncertain from the image.

AI-generated identification · may be incorrect

Rough, mottled turquoise-green to pale material with a dull to earthy luster. Chrysocolla hardness is variable, about 2–4 Mohs; it is typically massive rather than visibly crystalline and has no distinct cleavage.

AI Estimated Value

About $1–$10 for a small rough piece like this; gem-quality material can be worth substantially more.

Physical properties

Formation & geological history

Forms as a secondary copper mineral during weathering and oxidation of copper deposits, commonly in arid-zone veins and host rocks; its age depends on the deposit.

Uses & applications

Copper-bearing material may be processed as ore; attractive, more solid chrysocolla is used for cabochons and collectibles, though this specimen appears low-grade.

Geological facts

Chrysocolla’s vivid blue-green color comes from copper. Similar-looking materials include turquoise, malachite, and copper-stained host rock.

Field identification & locations

Look for blue-green, earthy copper-mineral patches associated with oxidized copper deposits; color alone cannot confirm the mineral. Common sources include Arizona, Chile, Peru, and the Democratic Republic of the Congo.
