Epidote is a calcium aluminium iron sorosilicate mineral, Ca2(Al, Fe)3(SiO4)3(OH), crystallizing in the monoclinic system.
Epidote
Chemical composition -- A family of closely related complex minerals. The best known and most valuable member of the family is a variety of zoisite better known as tanzanite, which makes gorgeous blue to purplish gems.
EPIDOTE
Overview: Epidote usually occurs in high-pressure, low-temperature calcium-bearing metamorphic rocks and as precipitates from magmatic fluids in igneous formations.
The vitreous to greasy lustered, translucent, frequently twinned crystals are found in association with glaucophane, quartz, chlorite, sphene, epidote, and garnet in gneisses and glaucophane schists formed under low temperature and high pressure, ...

Epidote: A silicate of alumina, lime, and oxide of iron, or manganese. It is commonly of a yellowish green (pistachio) color.

This epidote appears jet black and lustrous at first glance, but upon further examination evergreen hues start to shine through the translucent portions.

Epidote enhances one's perceptions, encourages participation with others, and is also an aid to self-esteem.
Quartz, among its many attributes, is the primary stone used for dissolving energy blockages.
Epidote is common in lenticular pods throughout the Canada Hill granite. It is found at the Philips Mine at westernmost prospect pits in the fault plane of the granite. Also visible as small yellow grains in quartz at the prospect pits.

Most distinguishing features:
Slight colour difference between this mineral and olivine, but only under magnification (where details in the crystals can be seen).
Garnets, epidote, clinozoisite, zoisite and other species such as actinolite, chrome diopside, talc and other mineral species have a string of recorded occurences in the region.

The rock is an interesting mix of red/pink feldspar, white/gray quartz and epidote (a pistachio-colored gemstone, calcium aluminum iron silicate hydroxide). Its coloring and compact, hard structure make it a nice stone for jewelry.
Zoisite is a calcium aluminium hydroxy sorosilicate belonging to the epidote group of minerals.
Unakite (New to the Market) Opaque granitic rock with main parts of aggregate being quartz and feldspar as well as greenish epidote. Very compact and hard. Named after place of discovery in South Carolina, USA.
Unakite is a mix of red, pink, white, grey and epidote (a pistachio-colored gemstone). Unakite is mined in the Southwestern U.S. and is a granite gemstone that is named after the Unaka Mountains.
Unakite is a variety of granite that contains green epidote and pink feldspar (but lacks mica). It has a hardness of 6 to 7 and a specific gravity of 2.86 - 3.2. Unakite was named for the Unaka Mountains Mountains in Tennessee, USA.
The gem consists of pink colored orthoclase feldspar, quartz and green epidote. Best quality Unakites are nowadays used in jewelries and also in lapidary works like carvings, eggs and spheres. This stone is also known as "epidotized granite".
Unakite is an altered granite, consisting of pink feldspar, green epidote and clear quartz. It is believed to help your inner self, build yourself confidence and help you grow from within.
In the sorosilicates or couplet silicates two silicate tetrahedra are linked into a pair by sharing a single oxygen ion. The most prevalent sorosilicates are members of the epidote group and are characterized by the mineral epidote, ...
Unakite, often referred as an epidotized granite, consists of a salmon-pink feldspar, green epidote, and quartz. The stone is an opaque coral and olive-green. Sometimes, other shades of green is also seen.
Unakite is an altered igneous rock, mainly composed of three minerals: pink feldspar, green epidote, and quartz
Metaphysical/Medical properties: Unakite is said to enhance self-awareness and perception and rid negative judgment.
It might be as simple as halite's (NaCl) or complex like, say, epidote (Ca2Al2(Fe3+,Al)(SiO4)(Si2O7)O(OH)), but if you were shrunk to an atom's size, you could tell what mineral you were seeing by its molecular makeup and arrangement.
Alaska.--Small dark green to dark brown to black colored stones have been cut from material from the epidote deposit on Prince of Wales Island.
Summary: Original tanzanite is a very rare kind of tone, occurring only in a small place in Tanzania, known as Merelani Hill, Arusha. It is actually a variety of Zoisite, which is the member of Epidote group, a silicate of calcium and Aluminium.
Many common minerals crystallize in this symmetry class, including azurite, clinopyroxene and clinoamphibole groups, datolite, epidote, gypsum, malachite, orthoclase, realgar, titanite, spodumene, and talc.
These minerals contain double silicate tetrahedra in which one of the oxygens is shared with an adjacent tetrahedron, so that the polyanion has formula (Si2O7)6-. An example is epidote (Ca2Al2FeO(OH)SiO4 Si2O7), a mineral common in metamorphic rocks.
A wide color range, green, from California and Pakistan, blue from Norway, yellow from New York, colorless from Siberia. Also found in violet, brown. Often confused with a variety of other stones, including demantoid, diopside, epidote, peridot, ...
The rarer stones, sphene and epidote, likewise exhibit this property markedly.
Perhaps the most familiar and valuable of the gem rocks is lapis lazuli, a mixture of the minerals lazurite, sodalite, Hauyne, calcite and pyrite. Other gem rocks include unakite (pink feldspar, green epidote, and quartz) and Chinese writing stone ...
Turquoise is often stabilized with a resin to preserve it's color, protect it from environmental pollutants and drying.
Unakite
Unakite is a mottled stone that is composed of several minerals including pink feldspar, green epidote and quartz.
