Peridot::: the Rock from Earth and Space: Yes, Peridot is not only born of fire here on Earth, but it has also arrived from outer Space. In 1749, a meteorite landed in a desolate area of Siberia. It was found to contain many pieces of peridot crystals, but today is mostly mined, it is made of iron-nickel matrix. The kind that came from Outer Space is also known as a Pallasite Meteor which is very rare. Only 61 are known to date, including 10 from Antarctica, with four being observed falls. The following four falls are in chronological order: - Mineo, Sicily, Italy. A luminous meteor was observed and an object seen to fall with a loud roar in May 1826. Only 46 grams (1.6 oz) are preserved in collections. - Zaisho, Japan. 330 g were found on February 1, 1898,[10] after the appearance of a fireball. - Marjalahti, Karelia, Russia. After the appearance of a bright meteor and detonations, a large mass was seen to fall and 45 kilograms (99 lb) were recovered in June 1902. At this date the fall site belonged to Finland, and the main mass of - -Marjalahti is now at the Geological Museum of the University of Helsinki. Omolon, Magadan Region, Russia. A reindeer-breeder observed the fall on May 16, 1981, and found the 250 kilograms (550 lb) meteorite two years later. The fall was confirmed by a meteorological station that had observed a fireball on the same date. Look out for Asteroids! Peridot has also been part of the lava and magma spewed forth from volcanic eruptions. In Hawaii, the black basalt rock and beaches are studded with millions of tiny peridot grains. Although most of the peridot on Hawaii is either too small to use, or is locked up in very hard rock and cannot be mined, some pieces of Hawaiian peridot have led to jewelry quality stones.... gemrockauctions/auctions/peridot/peridot-gemstones/item-259191
