Physical properties
Hardness of 7-7.5 on the Mohs scale, distinct pink center surrounded by a green outer rim, vitreous luster, trigonal crystal system, and indistinct cleavage.
Formation & geological history
Formed in lithium-rich granitic pegmatites through hydrothermal activity and fractional crystallization over millions of years.
Uses & applications
Primarily used in high-end jewelry, metaphysical collections, and as mineral specimens.
Geological facts
The unique color zoning occurs due to changing chemical conditions (iron and manganese concentrations) during crystal growth.
Field identification & locations
Easily identified by its simultaneous pink and green coloration in a single crystal; found notably in Brazil, Madagascar, Afghanistan, and Maine, USA.
