Physical properties
Hardness: 7 on Mohs scale. Color: Yellow to golden. Luster: Vitreous to waxy. Crystal structure: Trigonal (microcrystalline). Translucent to opaque.
Formation & geological history
Forms as a variety of quartzite or quartz with inclusions of mica or other minerals that give it a glistening effect and yellow color. Formed in metamorphic or igneous environments.
Uses & applications
Used in lapidary work, jewelry, carvings, and as a decorative stone. Often tumbled into smooth shapes or cut into beads and cabochons.
Geological facts
Aventurine is known for its 'aventurescence' – a shimmering or glistening effect caused by platy inclusions. Yellow aventurine specifically gets its color from iron-bearing minerals or mica.
Field identification & locations
Identified by its yellow color, hardness of 7 (will scratch glass), and slight shimmering effect depending on inclusions. Found in places like India, Brazil, and Russia. Often polished into cubes or tumbled stones for collectors.
