Green aventurine (likely)

Quartzite dominated by quartz (SiO₂), with green fuchsite mica inclusions

AI-generated identification · may be incorrect

Small polished/tumbled oval with medium green color, vitreous-to-waxy luster, and likely quartz granular structure; hardness about 6.5–7 Mohs, no obvious cleavage, specific gravity roughly 2.6–2.7. The image cannot confirm whether it is aventurine quartz, jade, or dyed chalcedony.

Physical properties

Formation & geological history

Typically forms when silica-rich material recrystallizes and incorporates chromium-bearing fuchsite during metamorphism; commonly Precambrian to younger metamorphic settings. Major sources include India, Brazil, Russia, and Tanzania.

Uses & applications

Used for beads, cabochons, carvings, ornaments, and inexpensive tumbled stones; occasionally used as decorative facing material. It has modest jewelry value.

Geological facts

Aventurine’s characteristic shimmering effect, called aventurescence, comes from reflective mica or hematite inclusions, though this specimen appears relatively uniform and non-sparkly.

Field identification & locations

Check for tiny glittering reflections, quartz-like hardness, and density; jade is generally tougher and may show fibrous texture, while dyed stones can show color concentration in cracks. A loupe, scratch test, and refractive-index measurement would improve identification.
