Unakite
Unakite is primarily found in the USA, but deposits have also been discovered in South Africa, Brazil and China.
Unakite is altered granite composed of pink orthoclase feldspar, green epidote, and generally clear quartz. It exists in various shades of green and pink and is typically mottled in appearance. In good quality, unakite is considered a semiprecious stone. It is also referred to as epidotized granite.
Unakite has a hardness of 6 to 7 on the Moh’s scale.
