Physical properties
Hardness: 7 on Mohs scale; Color: Dull light green to bluish-green; Luster: Vitreous to waxy; Crystal structure: Trigonal (microcrystalline); Cleavage: None; Specific gravity: ~2.65
Formation & geological history
Formed in metamorphic or igneous environments where quartz crystallizes alongside chromium-bearing fuchsite mica, giving it its characteristic green color and subtle aventurescence.
Uses & applications
Popular for lapidary work, tumbled stones, jewelry beads, decorative carvings, and crystal healing collections.
Geological facts
Aventurine is a form of quartz characterized by its translucency and the presence of platy mineral inclusions that produce a shimmering effect known as aventurescence.
Field identification & locations
Can be identified by its quartz-like hardness, pale green hue, and smooth tumbled surface. Found commonly in India, Brazil, and Russia. Collectors often look for rich color uniformness and sparkle.
