1.9" Polished Sericho Pallasite Meteorite (52.6 g) - Kenya

This is a 1.9" wide (52.6 grams) end-cut of a Sericho pallasite meteorite that was collected in 2016. These meteorites fragments found near the village of Habaswein had been known about for decades by camel herders, however they were disregarded until two brothers who were searching for their camels, stumbled upon them. Weeks of excavating ensued following their discovery. This fall site has produced over 2800 kg of the Sericho meteorite since 2016.

About Pallasites

Pallasite meteorites are a class of stony-iron meteorites. They were once believed to have originated at the core-mantle boundary of asteroids that shattered through impacts, but a recent hypothesis is that they are a mixture of core and mantle minerals.

Pallasite meteorites consist of olivine (peridot) crystals surrounded by iron-nickel matrix. Upon acid etching, some pallasites display interweaving structures known as Widmanstätten patterns (or Thomson lines) in the metallic matrix. These structures are iron-nickel alloy crystals, typically kamacite and taenite, that cooled over millions of years in the vacuum of space.

Pallasites are quite rare: only about 200 are known, and only four have had observed falls. This represents less than 0.2% of all classified meteorites!

Pallasite Care

Pallasites are even more susceptible than most iron meteorites to rusting and deterioration due to moisture in the atmosphere; proper care includes keeping them in moisture-free environments. This is particularly important in areas with high humidity, such as Florida. All pallasite material we sell has been stabilized in some way, which will help with this issue, but care still needs to be taken to keep your treasure in good condition. Keep pallasites stored in a moisture-free environment, preferably with a corrosion inhibitor such as silica gel beads or a dehumidifier.
