Physical properties

Polished, translucent green cabochon with faint glitter and possible internal fractures. Quartz has Mohs hardness 7, vitreous luster, and a trigonal crystal structure; no visible cleavage.

Formation & geological history

Forms when silica-rich fluids crystallize as quartz with fine mica inclusions, commonly in metamorphic rocks. Its geological age depends on the deposit.

Uses & applications

Used for cabochons, beads, carvings, and inexpensive jewelry or decorative objects.

Geological facts

Aventurine’s subtle sparkle, called aventurescence, comes from reflective mineral inclusions; green color is often due to fuchsite.

Field identification & locations

Look for a translucent green body and fine reflective flecks; glass imitations may have bubbles and lack natural mineral texture. Green aventurine is commonly sourced from India, Brazil, and Russia.
