Green-and-white quartz-rich rock, likely chrysoprase or serpentine-bearing stone

Uncertain; possible chrysoprase (microcrystalline quartz, SiO₂) or serpentinite (magnesium silicate minerals)

AI-generated identification · may be incorrect

Pale green and white, rough and massive with a dull to slightly waxy luster; estimated Mohs hardness 3–7 depending on composition, with no visible crystal structure or cleavage.

AI Estimated Value

About $1–$10 as an unidentified rough fragment; attractive confirmed chrysoprase may sell for $10–$50, while ordinary serpentinite is usually under $10.

Physical properties

Pale green and white, rough and massive with a dull to slightly waxy luster; estimated Mohs hardness 3–7 depending on composition, with no visible crystal structure or cleavage.

Formation & geological history

Could form through silica-rich groundwater alteration (chrysoprase) or hydration of ultramafic rocks (serpentinite); exact age and origin cannot be determined from the photograph.

Uses & applications

Chrysoprase may be used as a cabochon or ornamental stone; serpentinite is used decoratively and occasionally as dimension stone. This small rough specimen is primarily suitable for collecting.

Geological facts

The green color may result from nickel in chrysoprase or from serpentine minerals; these materials can look similar in an image. A hardness, streak, and acid test would help distinguish them.

Field identification & locations

Common possibilities include altered ultramafic terrains and silica-rich veins; test whether it scratches glass, examine its streak, and inspect for fibrous serpentine texture. Identification requires a close examination or laboratory testing.
