A meteorite mineral is a mineral found chiefly or exclusively within meteorites or meteorite-derived material. [citation needed] This is a list of those minerals, excluding minerals also commonly found in terrestrial rocks. As of 1997 there were approximately 295 mineral species which have been identified in meteorites. [1]
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]
A Meteorite mineral is a mineral found chiefly or exclusively within meteorites, as opposed to minerals also found commonly on Earth, such as Olivine. The main article for this category is List of meteorite minerals .
Like bronzite, it is sometimes cut and polished as a gemstone. [1] The name "hypersthene" comes from the Greek and means "over strength", and is an allusion to its being harder than the amphibole mineral hornblende (a mineral with which it is often confused.

Moldavite (Czech: vltavín) is a forest green, olive green or blue greenish vitreous silica projectile glass formed by a meteorite impact in southern Germany (Nördlinger Ries Crater) [3] that occurred about 15 million years ago. [4]
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 meteorite had disintegrated into 20 pieces weighing a total of 10 kilograms. In 1911 a meteorite was seen near Tonk in India. Only a few fragments were recovered that weighed a mere 7.7 grams (0.27 oz). [5] The meteorite of the type locality Ivuna in Tanzania fell in 1938 splitting into three pieces of altogether 705 grams (24.9 oz).
