Physical properties
Hardness of 7 on the Mohs scale, pale green to bright green color with white matrix, vitreous to waxy luster, microcrystalline (cryptocrystalline) quartz crystal structure, conchoidal fracture with no cleavage, specific gravity around 2.65.
Formation & geological history
Formed through the hydrothermal deposition of silica-rich solutions in nickel-bearing serpentine rocks or weathered nickel ore deposits.
Uses & applications
Used primarily for ornamental carvings, cabochons in jewelry, beads, and as a collector's mineral specimen.
Geological facts
The vibrant green color is caused by trace amounts of nickel, distinguishing it from other green varieties of chalcedony like prase, which is colored by green amphibole or chlorite inclusions.
Field identification & locations
Identified by its distinctive apple-green patches within a white quartz matrix, hardness exceeding steel, and waxy luster. Commonly found in regions with serpentinite such as Australia, Brazil, and the USA.
