Isheyevo, météorite ultra rare CH/CBb - 6.23 g - (1)

ISHEYEVO — 6,23 g — Le seul météorite CH/CBb officiellement approuvé
IMCA certificate of authenticity included.

Offered here is a 6.23 g specimen of Isheyevo, one of the most extraordinary and scientifically distinctive carbonaceous chondrites known.

Isheyevo occupies a truly unique position in meteoritics. According to the Meteoritical Bulletin Database, its recommended classification is CH/CBb, representing a transitional material between the CH carbonaceous chondrites and the CBb subgroup of CB chondrites.

Isheyevo is the only approved meteorite in the entire Meteoritical Bulletin Database classified as CH/CBb.

This makes the specimen remarkable on a level beyond simply being extraterrestrial material. Holding a piece of Isheyevo means coming into physical contact with a type of meteoritic material that, among all officially recognized meteorites, is represented by one single meteorite: Isheyevo.

In other words, its rarity is not merely that this material originated beyond Earth. It is that no other approved meteorite shares its CH/CBb classification.

Isheyevo was found in October 2003, near the village of Isheyevo in the Ishimbai region of Bashkortostan, Russia. A single stone weighing 16 kg was discovered by a tractor driver in a field during harvesting.
