Peridot can be found in mafic and ultramafic rocks occurring in lava and peridotite xenoliths of the mantle. The gem occurs in silica-deficient rocks such as volcanic basalt and pallasitic meteorites. Along with diamonds, peridot is one of only two gems observed to be formed not in Earth's crust, but in the molten rock of the upper mantle. [1]
Hibonite is closely related to hibonite-Fe (IMA 2009-027, (Fe,Mg)Al 12 O 19)) an alteration mineral from the Allende meteorite. [4] Hibonites were among the first minerals to form as the disk of gas and dust swirling around the young sun cooled. [5] A very rare gem, hibonite was discovered in 1953 in Madagascar by Paul Hibon, a French ...

The Maine Mineral and Gem Museum wants to add to its collection, which includes moon and Mars rocks, Pitt said, so the first meteorite hunters to deliver a 1-kilogram (2.2-pound) specimen will ...
Cree is the world leader in the growth of single crystal silicon carbide, mostly for electronics use. [19] In 1995 C3 Inc., a company helmed by Charles Eric Hunter, formed Charles & Colvard to market gem quality moissanite. Charles & Colvard was the first company to produce and sell synthetic moissanite under U.S. patent US5723391 A, first ...
