Blue-green quartz-rich stone, possibly chrysoprase or aventurine

Uncertain; likely quartz (SiO₂) with green coloration from nickel-bearing minerals or inclusions

AI-generated identification · may be incorrect

Translucent blue-green to gray-green, vitreous to waxy luster, irregular fracture, and no obvious cleavage; quartz hardness is about 7 Mohs, though the specimen may be softer if heavily altered or composite.

AI Estimated Value

Approximately $5–$30 as an unidentified rough specimen; confirmed attractive chrysoprase or quality lapidary material may range from $20–$150 or more.

Physical properties

Formation & geological history

Likely formed in silica-rich hydrothermal veins or weathered rock zones; exact geological age and identity cannot be determined reliably from the photograph.

Uses & applications

Potentially used as a lapidary or ornamental stone if confirmed as chrysoprase, green aventurine, or another quartz variety; the pictured rough piece has modest value.

Geological facts

The broad color and translucent patches resemble chrysoprase, aventurine quartz, or less commonly low-grade fluorite, but image-only identification is insufficient.

Field identification & locations

Test hardness against glass, inspect for quartz-like conchoidal fracture, and use a loupe to check for mica sparkles or veining; streak, specific gravity, and chemical testing would help distinguish possibilities. Common sources include Australia, Brazil, India, and the United States, depending on the variety.
