Zoisite is a calcium aluminium hydroxy sorosilicate belonging to the epidote group of minerals. Tanzanite is the blue/purple variety of the Mineral Zoisite which was discovered in the Meralani (Merelani Hills of Northern Tanzania in 1967 near Thulite (sometimes called rosaline) is an opaque massive pink Manganese rich variety of the Mineral Zoisite. Anyolite is considered a variety of the Mineral Zoisite. Found in Kenya and Tanzania, anyolite is actually a Metamorphic rock composed A Ruby is a pink to blood-red Gemstone, a variety of the Mineral Corundum ( Aluminium oxide) Calcium (ˈkælsiəm is the Chemical element with the symbol Ca and Atomic number 20 WikipediaNaming The silicate minerals make up the largest and most important class of rock-forming Minerals They are classified based on the structure of their silicate Ion group Epidote is a Calcium Aluminium Iron sorosilicate Mineral, Ca2Al2(Fe3+Al(SiO4(Si2O7O(OH A mineral is a naturally occurring substance formed through geological processes that has a characteristic chemical composition a highly ordered atomic structure and specific Its chemical formula is Ca₂Al₃(SiO₄)(Si₂O₇)O(OH).

Slovenia, officially the Republic of Slovenia (Republika Slovenija) is a Country in southern Central Europe bordering Italy to the west Sigmund Zois Freiherr von Edelstein, usually referred as Sigmund Zois or Žiga Zois in Slovene ( 23 November 1747 – 10 November The Duchy of Carinthia (Herzogtum Kärnten Vojvodina Koroška was a Duchy located in southern Austria and parts of northern Slovenia. Zoisite was first known as saualpite, after its type locality. Transparent material is fashioned into gemstones while translucent-to-opaque material is usually carved into sculptural works. A gemstone or gem, also called a precious or semi-precious stone, is a piece of attractive Mineral, which &mdash when cut and polished &mdash The latter is sometimes shot through with ruby crystals, which are completely opaque and unsuited to use as gems, yet are well colored and contrast strikingly against the green matrix of the zoisite.

Zoisite occurs as prismatic, orthorhombic (2/m 2/m 2/m) crystals or in massive form, being found in metamorphic and pegmatitic rock. General right and uniform prisms A right prism is a prism in which the joining edges and faces are perpendicular to the base faces In Crystallography, the orthorhombic Crystal system is one of the seven Lattice Point groups Orthorhombic lattices result from stretching In Materials science, a crystal is a Solid in which the constituent Atoms Molecules or Ions are packed in a regularly ordered repeating Metamorphic rock is the result of the transformation of an existing rock type the protolith, in a process called Metamorphism, which means "change Pegmatite is a very coarse-grained Igneous rock that has a grain size of 20 mm or more such rocks are referred to as pegmatitic. Zoisite may be blue to violet, green, brown, pink, yellow, gray, or colorless. It has a vitreous luster and a conchoidal to uneven fracture. Lustre (or luster) is a description of the way light interacts with the surface of a Crystal, rock, or Mineral. A fracture is the (local separation of an object or material into two or more pieces under the action of stress. When euhedral, zoisite crystals are striated parallel to the principal axis (c-axis). Also parallel to the principal axis is one direction of perfect cleavage. Cleavage, in Mineralogy, is the tendency of crystalline materials to split along definite planes creating smooth surfaces of which there are several named types Zoisite is somewhat higher than 6 in hardness and its specific gravity is between 3. The Mohs scale of mineral hardness characterizes the scratch resistance of various Minerals through the ability of a harder material to scratch a softer material Specific gravity is defined as the ratio of the Density of a given solid or liquid substance to the density of water at a specific temperature and pressure typically 10 - 3. 38, depending on the variety. Zoisite streaks white and is said to be brittle. Clinozoisite is a more common monoclinic polymorph of zoisite. Clinozoisite is a mineral a complex Sorosilicate of Calcium and Aluminium and is usually a grey green colour In Crystallography, the monoclinic Crystal system is one of the 7 lattice Point groups A crystal system is described by three vectors. Polymorphism in Materials science is the ability of a solid material to exist in more than one form or Crystal structure
