Physical properties

Hardness: 6.5-7 Mohs, Color: Translucent to opaque light green, Luster: Vitreous to waxy, Crystal Structure: Trigonal/Hexagonal, Specific Gravity: 2.64-2.69

Formation & geological history

Formed in igneous and metamorphic rocks (specifically quartzites) through the crystallization of silica-rich fluids. The green color comes from inclusions of chromium-rich mica called fuchsite.

Uses & applications

Used extensively for carvings, figurines (like this dinosaur), beads, cabochons for jewelry, and as a popular stone for lapidary collectors and metaphysical enthusiasts.

Geological facts

Aventurine is known for 'aventurescence,' a shimmering effect caused by light reflecting off tiny platy mineral inclusions throughout the host quartz.

Field identification & locations

Identify by its translucent green body and subtle shimmering inclusions. Commonly sourced from India, Brazil, and Russia. For collectors, look for uniform color and absence of cracks.
