Sericho Pallasite Meteorite Pendant
Created in the heart of an asteroid soon after the birth of the solar system, this necklace features a fragment of the Sericho Pallasite Meteorite. The setting is sterling silver with an open back to allow for inspection of the meteorite from all directions.
As pictured, the necklace comes with a handsome display/storage box and a small information card that also serves as the certificate of authenticity.
All components of the necklace are sterling silver, including the 18" (45cm) box-style chain.
Sizing: The pallasites measure just a little under 1/2" x 1/2" (12mmx14mm).
About the Sericho Pallasite Meteorite
In 2016, south of Sericho, Kenya, two brothers found several dense stones while searching for their camels. The two realized there were no rocks in the area besides these and decided they were meteorites. Soon, this was proven to be correct. The specimens were identified as pallasites, a rare class of stony-iron meteorites.
Pallasites are characterized by a unique matrix of the mineral Olivine embedded in solidified iron and nickel. The combination of such materials is as surprising to science as it is beautiful to the eye. The unusual matrix of the Pallasite is formed by the intrusion of molten metal into layers of Olivine. Olivine is made of magnesium iron silicate with numerous variations on Earth and beyond. We have discovered Olivine on the Moon and Mars and detected Olivine's spectral signature in the dust disks surrounding young stars and in comet tails. Peridot is the gem-quality variant of Olivine.
While this sort of mixing is likely to occur in the reaction zones between the core-mantle boundary in large bodies, gravity should separate these materials due to their varied densities. This is one reason that pallasite formation is such an active topic in the scientific community; it also explains why less than 1% of all found meteorites are classified as pallasites.
