Physical properties
Small rough, pale green-and-white specimen with dull to weakly sparkly luster and irregular fracture; likely hardness about 3–7 depending on composition. No clear crystal faces or cleavage are visible.
Formation & geological history
Green coloration may come from fuchsite mica, chlorite, or serpentine formed during metamorphism and hydrothermal alteration. Geological age cannot be determined from the photograph.
Uses & applications
Commonly used as decorative stone, lapidary material, beads, or a teaching specimen; this fragment has little commercial value unless confirmed as an attractive gem material.
Geological facts
The image is insufficient for a reliable species identification; several green minerals look similar in rough fragments.
Field identification & locations
Check streak, hardness, translucency, and specific gravity: quartz-rich material scratches glass, while serpentine is much softer and may show waxy luster. Common source regions include India, Brazil, Russia, and the United States.
