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]
Eucrites are achondritic stony meteorites, many of which originate from the surface of the asteroid 4 Vesta and are part of the HED meteorite clan. They are the most common achondrite group with over 100 meteorites found. Eucrites consist of basaltic rock from the crust of 4 Vesta or a similar parent body.
Artist's conception of a multitude of tiny diamonds next to a hot star. In 1987, a team of scientists examined some primitive meteorites and found grains of diamond about 2.5 nanometers in diameter (nanodiamonds). Trapped in them were noble gases whose isotopic signature indicated they came from outside the Solar System. Analyses of additional ...
Since the characteristics of lonsdaleite are unknown to most people outside of scientists trained in geology and mineralogy, the names "lonsdaleite" and "hexagonal diamond" have frequently been used in the fraudulent sale of worthless ceramic artifacts, passed off as meteorites on online e-commerce sites and at street fairs and street markets ...

A calcium–aluminium-rich inclusion or Ca–Al-rich inclusion (CAI) is a submillimeter- to centimeter-sized light-colored calcium- and aluminium-rich inclusion found in carbonaceous chondrite meteorites. The four CAIs that have been dated using the Pb-Pb chronometer yield a weighted mean age of 4567.30 ± 0.16 Myr.
Meteorites themselves aren’t the only valuable items created by impacts. Items struck by meteorites also sell for high prices, such as a doghouse from Costa Rica that was struck by a meteorite.
An achondrite [1] is a stony meteorite that does not contain chondrules. [2] [3] It consists of material similar to terrestrial basalts or plutonic rocks and has been differentiated and reprocessed to a lesser or greater degree due to melting and recrystallization on or within meteorite parent bodies.
