Brahin pallasites were first discovered in Byelorussia (White Russia) in 1810. Extremely rare, pallasites represent only 0.2% of all meteorites. Their rarity is due to having originated from asteroid’s mantle/core boundary. The term “pallasite” is in honor of the German scientist, Peter Pallas, who in 1749 discovered the first pallasitic mass in Siberia.
On the flat cut and polished surface of the lot now offered, a mosaic of sparkling olivine (magnesium iron silicate) crystals from the asteroid’s mantle is suspended in its gleaming iron-nickel matrix originating from the asteroid’s core. The reverse features the meteorite’s natural external surface. The reverse features the meteorite’s natural external surface. Shallow dimpling of olivine is surrounded by elevated ridges of metal — every bit of which is blanketed in a rich oxidized patina with russet accents from its residency on Earth. The search for additional specimens from the Brahin event is now constrained as the Chernobyl nuclear reactor was built extremely close to Brahin’s impact zone and the strewn field is off limits. Recovered long before the Chernobyl disaster, this choice example provides a captivating reveal of the interior and exterior of a pallasite.
