| Garnet |  Garnet is a family of minerals that have been employed since the Bronze Age as precious stones and abradants. Garnets are most regularly occured in red, but are offered in a broad range of colors including the full spectrum. The name "garnet" originates from the Latin granatus ("grain"), perhaps a mention of the Punica granatum ("pomegranate"), a plant with red seeds alike in form, dimension, and color to a number of garnet crystals.
Six general kinds of garnet are known grounded on their chemical structure. They are pyrope, almandine, spessartite, grossular (kinds of which are hessonite or cinnamon-stone and tsavorite), uvarovite and andradite. The garnets create two hard solution ranges: 1. pyrope-almandine-spessarite and 2. uvarovite-grossular-andradite.
Garnets are discovered in lots of colors comprising red, orange, yellow, green, blue, purple, brown, black, pink and colorless. The blue garnet occurs extremely rare, one of these stones was found in the late 1990s in Bekily, Madagascar. Besides it is found in some parts of the United States, Russia and Turkey. Its color may vary from blue-green in the light of day to purple in luminous light, as a consequence of the comparatively big quantity of vanadium (about 1 wt.%). In addition other kinds of garnets with unstable color are present. In the light of day, their color varies from hues of green, light brown, brown, gray, and blue, but in luminous light, they seem to be ruddy or purplish/rosy in color. Due to their color varying property, this type of garnet is frequently considered as Alexandrite.
Garnet’s light transferring qualities can vary from the gemstone-worth clear varieties to the non-transparent specimens employed for manufacturing functions as abradants. The stone’s luster is determined as glassy or tarry (amber-like).
Garnet is the January birthstone. Garnet is a group of natural materials having parallel physical and crystalline qualities. They all have the similar universal chemical formula, A3B2(SiO4)3, where A could be calcium, magnesium, ferrous iron, or manganese, and B can be aluminum, ferric iron, or chromium, or in rare cases, titanium.
