Maggiore - a rare form of pomegranate purple. Madzhority arise either under the influence of fallen meteorite impact, or under the ground at a depth of not less than 400 miles! Named in honor of Alan geophysics Majora, who investigated the formation of garnet under high pressure.
First Maggiore was found in 1970 in a meteorite Koorara near the town of Yecla, in Western Australia. In 1990 he was found a few large crystals of Madagascar, near Bekili. Multiple instances in the next decade was found in Russia, Turkey and the United States. The most recent find is dated 2004, when in France, in the region of Shantoneo was found about a thousand slyudoobraznyh crystals, polished and subsequently sold at the price of $ 2,400 per carat.The most expensive to date, purple garnet Maggiore, weighing 4.2 carats , was sold in 2003 for 6.8 million dollars.

TAAFFEIT
743664_c971b2b4dd337cfa6b78f6e247f (200x150, 7Kb)

Taaffeit one of the most rare and unique collection of stones. For all the times it has been found a very small number of these stones, and most of them had been erroneously recognized as spinel. To date, only in Sri Lanka and Tanzania, from time to time there is a unique mineral. Since geological deposits in East Africa and Sri Lanka are related to our colleagues calculated to find Taaffeit also in Madagascar.
In 1945, Count Taaffe, Dublin gemologist found a pale pink-purple stone in the box with the waste jewelry workshop.In appearance and properties of spinel stone reminded him, but showed a clear birefringence. Stone was sent to the British Museum for analysis, where it was determined that this stone is unknown mineral. Although the index of refraction is approximately the same as that of spinel taaffeit uniquely determined because of its double refraction and uniaxial negative characteristic.
Despite the constant search for the other taaffeit was found only in 1949, in a package with a scattering of stones from Sri Lanka. The third stone was found in 1957 by Robert Krouningshildom, expert GIA. Fourth taaffeit was found only 10 years later.
Since then, gemologists have been more or less aware of taaffeite and individual stones continue to be discovered.Several years ago, our partners, owning mines in Tunduru, Tanzania, found several taaffeitov in its raw material material raised to the surface of the mine. Since then launched an ongoing process of rechecking of all the material in the odobennosti - spinel, to detect the effect of double refraction. In the case of the slightest suspicion or uncertainty under further investigation by the most modern equipment. Due to this over the past 5 years, only in Tanzania was found a few hundred taaffeitov. The largest known today taaffeitov weighs 9.31 carats.
The world price for Taaffeit ranges from 2,000 to 10,000 dollars per carat

MUSGRAVIT
743664_65efbc32c45b7448a5151c60e43 (200x150, 8Kb)
Do taaffeita have a very close relative - chemically and optically similar to it musgravit . The mineral was first discovered in the valley Musgreyv Range, thus earning its name. Later musgravit mineral was discovered in Grenkandii, Madagascar, Tanzania and even in Antarctica !!! But all of these samples could only be used for wall cladding, which was carried out by the Sultan of Brunei in one of its bedrooms .. And here is the first sample, suitable for cutting in the gem was discovered only in 1993. For some time it was thought that taaffeit and musgravit there are one thing, but in 2003 the study of the two stones on the Raman spectroscopy, using a green laser were obtained dokazatelsyva that taaffeit and musgravit - different minerals and different stones.
In 2005 it was reliably confirmed the existence of only 8 musgravitov, now known for 14 of these stones. The largest has a weight of 5.93 carats (submitted photo).
Benitoite
743664_bfd40a25f989a1e18930ac59cb2 (200x150, 6Kb)
The only field in the world benitoite was found only in San Benito County, California. Benitoite - Stone intensely blue, with a very strong dispersion comparable to diamond, with intesnivnoy white and blue fluorescence under ultraviolet light.
The largest known benitoite weighs 15.42 carats, but stones weighing more than 1 carat are extremely rare, they know no more than ten. In 1974, at Zurich Airport was stolen 6.52-carat VVS drop benitoite, the loss has not yet been detected. There is a reasonable expectation that the stone was cut and peregranen 2 smaller and sold later on one of the closed auctions.
Since 1984, the state benitoite considered the jewel of California. The world market price of 1 carat small benitoite varies, depending on the quality, from 500 to 4000 dollars per carat.
RED DIAMOND
743664_ea78ad5df2214addf5770e15ee3 (210x300, 12Kb)
Only a few red diamonds have been found in the history of mankind, and very few people had the good fortune to see them and hold in their hands. The natural color of the red diamond is described as gemologists purpurnovato red, that is not a pure red (ruby). Regardless of the size of the red diamonds along with natural black diamonds are among the rarest and most expensive gemstones in the world. The world's only commercially mined deposits of colored diamonds in Argyle, Australia, annually produces calculate the number of red - and okolokrasnyh diamonds, in some years - only several carats .. Red diamonds weighing over 0.1 carats sold as a rule only through auctions, and their cost millions of dollars per carat.
