While meteorites are among the rarest substances on Earth - all the world's meteorites weigh less than the world's annual gold production - pallasites are increasingly rare, accounting for less than 0.2% of all known meteorites. Pallasites formed at the boundary between the core and mantle of the parent asteroid when part of the olivine mantle, which is near the molten metal core, crystallized. As a result of the asteroid breaking apart after a collision with another asteroid, the inner parts of that asteroid broke free and some of them found their way to Earth. Some pallasites-including the current offering-contain gem-quality olivine/peridot.
You will find pallasites from well-known and lesser-known localities.
