A low to medium-temperature metasomatic rock mostly formed by the alteration of granitic rocks; principally composed of epidote, K-feldspar and quartz.
A popular material for cabochons, unakite, an altered granite, contains green epidote, white to gray quartz, and pink feldspar (orthoclase).

Some epidotes may have a hardness of 7, on par with quartz. However, most gem materials in this supergroup have a hardness of 6 or softer. Since these gems also have perfect cleavage and sensitivities to heat and acids, clean them only with a soft brush, mild detergent, and warm water. For jewelry use, have these stones set in protective settings and/or reserve them for occasional wear.
