Bixbite / Violet Claims, Wah Wah Mountains, UtahÄesignated the world's rarest coloured gemstone in 2006 by the Jewellers association. Descriptions and photographs of Missouri rock and mineral occurrences are. Since the supply is so limited, red beryl deserves its moniker of the rarest coloured gem on Earth. Coring in the early noughties determined that large scale mining techniques would not be viable, and the claim has been inactive ever since, due to the extremely high price tag. The Ruby Violet mine was first found by a Uranium prospector in 1958, and since then has had a long series of owners, all of whom have run into the problem that the mineralisation is so rare that the mine can't produce enough to be financially viable. Like pezzotaite, the colour comes from impurities of manganese. A laboratory certificate is strongly recommended when buying one. It has also been mis-sold under the name red emerald (since emerald is by definition green), and can be visually confused with beryl's pink cousin pezzotaite. It was originally called Bixbite (after the American mineralogist who discovered in 1904), but the name red beryl was adopted to avoid confusion with Bixbyite, also named after Maynard Bixby. The gases flowed along the columnar joints (like those at Giant's Causeway in Ireland) forming beryl and topaz, the gemmy relics of tectonic forces some 22 million years ago. In this case, though the Beryl formed directly from a gaseous state, when a younger rhyolite intruded beneath the one in which it formed some few million years later, and the gasses flowed up as it cooled by interaction with groundwater in the older lava to precipitate the gems at temperatures of 300-650 Celsius. Red beryl is a rare mineral because its formation requires a unique geochemical environment. Red beryl receives its red color from trace amounts of manganese. The quantity of all variations of Arkonor will be reduced. The quantity of all variations of Bistot will be reduced by 70. The quantity of all variations of Kernite will be reduced by 75. It usually forms in pegmatites, the last remains of granites to slowly crystallise, producing large crystals sometimes filled with rare elements distilled out of the planet by volcanism. All variations of Scordite, Plagioclase, Omber, Jaspet, Hemorphite, Hedbergite, Gneiss, Dark Ochre, and Crokite will be removed from Nullsec asteroid belts. Beryl, of course, the same mineral that gives us lovely blue aquamarines or yellow heliodor (when coloured by Iron), green emerald (chromium) and pink morganite (manganese). ![]()
