African Garnet
Many members, old and newly discovered have come from Africa. A grossular garnet named Tsavorite is found in Kenya around the Tsavo National Park area. It is also said to be found in East Africa in Tanzania from which it was imported into the United States by Tiffany and Company. Tavorite comes in shades of green mainly because of it's chromium and vanadium composition and has, at times, been mistaken for emeralds for this reason. Malaya garnet, an orange to saturated yellow, also has deposits in Tanzania and Kenya. Mandarin, another orange garnet of the spessartite class, is found in Namibia along with Andradites. Another rare form of garnet found in Africa is the Imperial garnet, which of the grossular classification. Other garnets ranging in color from browns and yellows to greens as in African Jade found in parts of South Africa. Other sources for garnets reside in Zimbabwe and Mozambique (produces a medium pink to muave/purple garnet, a combination of pyrope and almandite).
Properties
Garnets species are found in many colors including red, orange, yellow, green, blue, purple, brown, black, pink and colorless. The rarest of these is the blue garnet, discovered in the late 1990s in Bekily, Madagascar. It is also found in parts of the United States, Russia and Turkey. It changes color from blue-green in the daylight to purple in incandescent light, as a result of the relatively high amounts of vanadium (about 1 wt.% V2O3). Other varieties of color-changing garnets exist. In daylight, their color ranges from shades of green, beige, brown, gray, and blue, but in incandescent light, they appear a reddish or purplish/pink color. Because of their color changing quality, this kind of garnet is often mistaken for Alexandrite.
Garnet species’s light transmission properties can range from the gemstone-quality transparent specimens to the opaque varieties used for industrial purposes as abrasives. The mineral’s luster is categorized as vitreous (glass-like) or resinous (amber-like).
Color change garnets
Garnet members of the pyrope-spessartine solid-solution series from Bekily in Madagascar display several colors depending on the light source. The alexandrite-like color change from blue-green in daylight to purple in incandescent light is mainly caused by relatively high amounts of vanadium. Although they look a lot like alexandrites they are different because they change color throughout the day. They are green or blue grey in the early morning and reddish in the late afternoon or in strong sunlight. Bekily garnets will appear red in the afternoon while the alexandrites remain green. Garnets from other parts of East Africa also change color but as they normally change from brown or orange to red, they don't look much like alexandrite.
Some of the stones are almost blue especially under fluorescent light but most of them are grey blue or green in daylight and change to red under incandescent or late afternoon light. The stones can show an excellent color change and can easily be confused with alexandrite.
Madagascar, or Republic of Madagascar (older name Malagasy Republic, French: République malgache), is an island nation in the Indian Ocean off the southeastern coast of Africa.
As part of East Gondwana, the territory of Madagascar split from Africa approximately 160 million years ago; the island of Madagascar was created when it separated from the Indian subcontinent 80 to 100 million years ago.
Pure crystals of garnet are used as gemstones. The gemstone varieties occur in shades of green, red, yellow and orange.
In the USA it is known as the birthstone for January. It is the state mineral of Connecticut. It is also New York's gemstone.
Pyrope, Greek for fiery, was the stone of the 18th and 19th centuries (Schumann, 1997). Pyrope is deep red to reddish black in color. Its chemical composition is Mg3Al2(SiO4)3. The best place to collect pyrope is from peridotites conta
