Quartz, SiO₂, with green fuchsite or other inclusions
AI-generated identification · may be incorrectPolished, translucent-to-opaque pale green cabochon with a vitreous to slightly waxy luster. Quartz hardness is 7 Mohs; trigonal crystal structure, no cleavage, and specific gravity about 2.65. The photo alone cannot confirm the stone; green jade or dyed material can look similar.

Physical properties
Polished, translucent-to-opaque pale green cabochon with a vitreous to slightly waxy luster. Quartz hardness is 7 Mohs; trigonal crystal structure, no cleavage, and specific gravity about 2.65. The photo alone cannot confirm the stone; green jade or dyed material can look similar.
Formation & geological history
Aventurine forms when quartz crystallizes with fine mineral inclusions, commonly in metamorphic rocks; its age depends on the host deposit.
Uses & applications
Used for beads, cabochons, carvings, and inexpensive jewelry or decorative objects.
Geological facts
Fine reflective inclusions can create aventurine’s characteristic glitter, though it is not prominent in this specimen.
Field identification & locations
Commonly sourced from India, Brazil, Russia, and elsewhere. Check for quartz-like hardness and subtle glitter; identification may require testing, since appearance alone is inconclusive.
