Physical properties

Hardness: 7 Mohs scale; Color: Creamy yellow to golden orange; Luster: Vitreous to waxy; Crystal structure: Trigonal/Hexagonal; Cleavage: None; Specific Gravity: 2.64-2.69

Formation & geological history

Formed in metamorphic rocks and igneous veins when molten rock cools or during regional metamorphism where quartz crystallizes with mica or pyrite inclusions. Primarily sourced from India, Brazil, and Russia.

Uses & applications

Decorative use, tumbled stones for collection, lapidary work, jewelry, and metaphysical practices.

Geological facts

Yellow Aventurine is a variety of quartz characterized by its 'aventurescence,' an optical effect caused by plate-like mineral inclusions. While green is the most common color, the yellow hue is typically caused by inclusions of mica or iron minerals.

Field identification & locations

Identify by its translucent to opaque yellow-orange color and the subtle shimmer when turned under light. Commonly found in large deposits as massive pieces rather than distinct crystals.
