Physical properties

Hardness of 7 on the Mohs scale, white to clear quartz base with distinctive green earthy patches (celadonite or similar green earth minerals), vitreous to greasy luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65.

Formation & geological history

Formed hydrothermally in cavities or veins where silica-rich fluids crystallized around preexisting green clay minerals, trapping them inside or on the surface of the quartz host.

Uses & applications

Used primarily as a collector's specimen, decorative stone, and in lapidary arts for cabochons.

Geological facts

Inclusions like green earth or celadonite give quartz stones unique mossy or scenic patterns, making each specimen entirely unique.

Field identification & locations

Can be identified by the hard quartz body combined with soft, earthy green patches that do not scratch glass. Found globally in hydrothermal vein systems and alluvial deposits.
