Physical properties
Hardness of 6 to 6.5 on the Mohs scale, vibrant turquoise-green color with white mottled grid patterns, vitreous luster, and specific gravity around 2.56.
Formation & geological history
Formed in pegmatites and granitic rocks through the slow cooling of magma, often associated with hydrothermal activity.
Uses & applications
Widely used in gemstone jewelry, decorative carvings, and as a popular specimen for mineral collectors.
Geological facts
Its distinct green-blue color was historically attributed to copper, but modern research shows it is caused by trace amounts of lead and water within the crystal lattice.
Field identification & locations
Identified by its characteristic opaque greenish-blue hue and distinct cross-hatch twinning. Found in locations like Russia, the USA, and Brazil.
