Pallasites are stony-iron meteorites that contain colorful peridot (olivine) crystals that can be cut into gems. Impactites are often colorful glasses that can be faceted, cut into cabochons, or carved into small sculptures.

Peridot (/ ˈ p ɛ r ɪ ˌ d ɒ t,-ˌ d oʊ / PERR-ih-dot, -⁠⁠doh), sometimes called chrysolite, is a yellow-green transparent variety of olivine. Peridot is one of the few gemstones that occur in only one color. Peridot can be found in mafic and ultramafic rocks occurring in …

GIA researchers Dr. Andy Shen, John Koivula and Dr. James Shigley assembled specimens from several terrestrial locales and compared them with 26 samples taken from the Esquel meteorite, the most notable peridot-bearing extraterrestrial object.

2024年5月7日 · Where you can find pallasite peridot (meteorites) Pallasite peridot doesn’t really “grow” here like other peridots. Instead, it arrives here inside meteorites that have traveled through space. When these space rocks land on Earth, we sometimes find them with beautiful green peridot crystals inside.

2011年11月11日 · This suite of pallasitic peridot (0.17–1.40 ct) from the Jepara meteorite contains colorful needle-like inclusions. Photo by Robison McMurtry; courtesy of Bradley Payne. Pallasite is a rare type of stony iron meteorite that contains crystalline olivine.

It is a piece of gem-quality olivine (peridot) from a pallasite meteorite, and it has been faceted into a wonderful little gemstone. This may be the most scarce gem material on Earth - but it actually originated in space.

2020年7月22日 · These peridot-containing meteorites are known as pallasite, and the gems they contain are known as pallasitic peridot. Due to the extreme conditions endured by extraterrestrial stones, examples of faceted pallasitic peridot usually weigh less than half a carat (A.H. Shen et al., “ Identification of extraterrestrial peridot by trace elements ...

Olivine is better known as “Peridot” amongst the gemological community, hence the use of expressions such as “gemstone meteorites” to describe Pallasites. This particular meteorite is an estimated 4,5 billion years old.

2020年4月29日 · Peridot is a gem-quality olivine and a (Mg, Fe)2SiO4 type silicate mineral. The formulation approaches Mg2SiO4 because it is a magnesium-rich olivine (forsterite). The green colors of the gem depend on the structure of the iron contents. It occurs both in volcanic basalt and in pallastic meteorites in silica-deficient rocks.

2023年8月23日 · Think your August birthstone, peridot, is out of this world? You’re right! Peridot belongs to the mineral family olivine, and olivine is found not only in volcanic sands in Hawaii and the deserts of the American Southwest, but in meteorites called pallasites. The pallasite type of meteorite is embedded with olivine crystal inclusions.
