Physical properties

Hardness: 7 Mohs; Color: Yellow to gold-orange; Luster: Vitreous to waxy with aventurescence; Crystal structure: Trigonal/Hexagonal; Cleavage: None

Formation & geological history

Formed in magmatic and metamorphic environments where quartz crystallizes with mica or iron oxide inclusions. The yellow color is typically caused by inclusions of mica or hematite/goethite.

Uses & applications

Commonly used for tumbled stones, decorative carvings, cabochons for jewelry, and in New Age practices as a healing crystal.

Geological facts

Yellow aventurine is known for its 'aventurescence,' a shimmering effect caused by platy mineral inclusions. It is often mistaken for citrine or orange calcite, but its hardness is a key difference.

Field identification & locations

Identify in the field by its hardness (will scratch glass) and the presence of tiny internal reflections or mica flakes. Frequently found in India, Brazil, and parts of Russia.
