Epidote exists in a multifaceted form, comprising of calcium aluminium, iron silicate, wherein metals such as ferric iron or Yttrium, Manganese and Cerium substitute for Aluminium and Calcium ions. Since Epidote is a product that is liable to alteration, the chemical formulae and composition are subject to a lot of variations. Based on the true intensity of Manganese, Iron and other elements, stones are graded either by a trade name or as a distinct mineral itself.
Zoisite is well known on account of its violet-blue form, when it is called Tanzanite
Tawmawite is a kind of Epidote, dark green in color, with a high content of chromium; it is mined from Burma
Clinozoisite is a form of Epidote that is white to pink in color with a less proportion of iron content
Unakite is a transformed form of granite with distinguishing features of Epidote and is frequently used in cabochon jewelry.
Piemontite is an opaque form of manganese Epidotethat is red in color
Ca2 (Fe, Al) 3 (SiO4) 3 (OH) - Calcium aluminum iron silicate
Derivation Of Name
This mineral obtains its name ‘Epidote’ from the Greek word “epidosis, which means ‘addition’, in reference to the many crystal faces in which it occurs. Even though this mineral occurs in nature, it is uncommon as a faceted gemstone and infrequently used as a gem
The Epidote is a mineral that is found in abundance, forming rocks. However, its origin is secondary. It occurs in the metamorphic state as schistose rock and marble and in the hydrothermal transformation of many minerals, such as(Micas, Feldspars, Amphiboles, Pyroxenes, Garnets and many others), it is obtained as a product in the composition of igneous rocks.
For those who collect minerals, the main forms in which they desire it are the most lustrous crystal and the elongated form, particularly unified. Occasionally collectors require Epidote with faces transparent and dark-green in color, having trendy forms inclusive of, octagons, cushions and ovals.
Epidote is found in the different geological surroundings, frequently Hornfels are formed when it comes in contact with metamorphosed limestone and metamorphic silicate rocks. We come across them even among igneous rocks and infrequently, they are formed in granite pegmatites.
As per mineral data, you can obtain supplies of Epidote deposits from several regions on the planet inclusive of Australia, Brazil, Austria, China, and the likes.
There are several clear forms of Epidote crystals, ranging from opaque to transparent; The most precious ones are the transparent crystals.
Green, white, sky-blue to yellowish blue and brown.
