Esquel The Most Beautiful Pallasite. Discovered in 1951 by a farmer in Chubut, Argentina, the single 680 Kg meteorite known as Esquel has been in great demand as the most beautiful of the rare type of meteorites known as pallasites. There are three major types of meteorites, iron, stony and stony-iron. Pallasites are stony-iron meteorites that originate from the core-mantle boundary of large planetary size asteroids that were destroyed early in the formation of the solar system. This rare type of meteorite consists of iron-nickel from the core of the asteroid as well as olivine crystals known as peridot from the mantle. Peridot crystals(the gem state of olivine crystals) are the only known gem stones from space found in meteorites. Esquel is considered to be the most beautiful of all pallasites and in now rarely available as the single discovered meteorite has been completely sectioned with only the main mass end piece remaining. This 2.75X1.25 inch section of Esquel has been polished on both sides to get the maximum reflection of the iron-nickel matrix as well as displaying many beautiful translucent lightly shocked green to orange olivine crystals. It weighs 18.56 grams and is presented in a 5.5X4.5 inch Riker mount.
Estimated Value $800 - 1,000.
