Garnets

Garnets, known in ancient China as Purple Crow's Nest or Zi Ya Wu, are a group of minerals that have been used as gemstones and abrasives since the Bronze Age. Commonly red in color, garnet is derived from the Latin "granatus" ("grain"), probably from "Punica granatum" ("pomegranate"), a plant with red seeds whose shape, size, and color are similar to some of the garnet crystals.

[Origin]

①Magnesian Aluminum Garnet is produced in the former Soviet Union, Norway, the Czech Republic and Jiangsu Province, China, and large grains of gem-quality Magnesian Aluminum Garnet are rare;

②Magnesia-iron garnet is mainly produced in the United States and Tanzania and other countries;

③Ferroaluminum garnet originates from Sri Lanka, Brazil, Madagascar, India and other countries;

④Calcium-aluminum garnet output in Kenya, Pakis, the former Soviet Union and China;

⑤Cinnamon garnet is produced in Sri Lanka;

⑥Gem grade in manganese-aluminum garnet is produced in Myanmar/Denmark, Sri Lanka, Brazil and other countries;

⑦Calcium-iron garnet is produced in the former Soviet Union and Congo;

⑧Calcium-chromium garnet is found in the former Soviet Union and the United States.

[Color]

The color of garnet is affected by the composition, showing a variety of colors, including red series including red, pink, purple red, orange red; yellow series including yellow, orange yellow, dense yellow, brown yellow; green series including emerald green, olive green, yellow green.

[Types]

Common garnets are recognized as six types according to their chemical composition, namely magnesium-aluminum garnet (Pyrope), ferroaluminum garnet (Almandine), manganese-aluminum garnet (Spessartite), calcium-ferrous garnet (Andradite), calcium-aluminum garnet (Grossular, with variations of tsavorite and hessonite), and garnet (Grossular), which is a variety of garnet with the same color. hessonite)) and calc-chromium garnet (Uvarovite).
