Pyrope - a mineral of garnet. Name from the Greek. piropos - "reminiscent of fire", caused by the color of the mineral. Variety Gemmological character: rhodolite. In antiquity and later pyrope (and other red stones) called carbuncles; now erroneously called a ruby mountain (English rock ruby).
Color: pink-red, orange-red, purple and dark red, pure pyrope may be colorless.
Shine: glass.
Hardness: 7-7.5 on the Mohs scale.
Density: 3,52-3,87 g/cm3.
Cleavage: none; fracture conchoidal, brittle.
Deposits, Czech Republic (Trebnitz) - extract from antiquity to the alluvial gravel and sand, known as Czech or Bohemian garnet Bohemian or precious stones; Scotland (Ross County), Russia (the Caucasus and the region of Lake Baikal), USA (San Juan County, Utah, Apache County, Arizona, McKinley County, New Mexico), Australia (Anaky, Queensland and the mountains of New England, New South Wales), Germany (Saxony), Norway, India (Madras), Brazil (Gravata ) Argentina (Cordoba and San Martin in the province of San Luis), South Africa, Namibia, Sudan, Tanzania (Shinyanga), Poland - Sobutki in serpentinites in Lower Silesia.
Usage: widely used in jewelry, but large specimens without admixtures are rare, mass-rimmed stones rarely exceed two carats. Much larger than a grenade with intermediate compositions (pyrope-almandine and pyrope-spessartine) is the main jewelery material. Of particular interest are mixed crystals of pyrope and spessartine showing the color change when changing the lighting. For example, Norwegian pyrope (about 65.2% molarnyh pyrope) in daylight - violet under artificial - red, as specimens mined in northern Tanzania in the daylight colored greenish-blue color, with artificial light - in purple. Pyrope is a valuable collector's stone. The most beautiful stones are in the Museum of Art in Vienna and at the Dresden Museum.
