Epidote A mineral not often used in jewellery today, but one which has been used sporadically for several hundred years. Its colour is normally a yellowish green, however it can also be found grey, brown or nearly black.
The gem is formed in metamorphic rocks and has high iron content. Although it is widely abundant, gem-quality Epidote is rarely found. When it is discovered, it is similar to Tourmaline in appearance and displays beautiful pleochroism and good transparency.
The gem has been unearthed in New York, Australia, France and Russia.
