Physical properties
Hardness: 7 on Mohs scale; Color: Pale to deep green; Luster: Vitreous to waxy; Crystal structure: Trigonal (microcrystalline); Cleavage: None; Specific gravity: 2.64-2.69. It features aventurescence (a metallic glitter).
Formation & geological history
Forms in metamorphic rocks like phyllites and schists, or in hydrothermal veins where quartz crystallizes with mica inclusions. Common in Precambrian and more recent terrains.
Uses & applications
Extensively used in lapidary work for cabochons, beads, figurines, and ornamental carvings. Also used in aquarium decor and landscaping.
Geological facts
The green color is primarily caused by platy inclusions of Fuchsite (chromium-rich muscovite mica). It is often called the 'Stone of Opportunity' in metaphysical circles.
Field identification & locations
Identify by its characteristic shimmer (aventurescence) and quartz-like hardness. Found predominantly in India, Brazil, and Russia. It lacks the 'greasy' feel of jade.
