Physical properties

Hardness: 7 on Mohs scale; Color: Pale to medium green with orangey-brown iron staining; Luster: Vitreous to waxy; Structure: Hexagonal (trigonal); Translucent.

Formation & geological history

Formed primarily in metamorphic environments where quartz-rich sediments are subjected to heat and pressure, allowing mica (fuchsite) to incorporate into the silicate structure.

Uses & applications

Used extensively in lapidary work, jewelry (beads, cabochons), tumbled stones for collecting, and decorative carvings.

Geological facts

Aventurine is known for its 'aventurescence,' a shimmering effect caused by platy mineral inclusions. While usually green, it can also be found in blue, orange, and red varieties.

Field identification & locations

Identified by its grainy quartz texture and green hue. It is commonly found in India, Brazil, and Russia. Collectors often look for even color distribution and strong shimmering effects.
