Mesosiderites are rare meteorites composed of a mixture of silicate minerals and metallic iron-nickel formed during major asteroid collisions early in the Solar System

The polished surface reveals the characteristic brecciated structure where silicate clasts are embedded within a metallic matrix

This specimen is a natural slice (unpolished)

Brachinite NWA 11756 (4.70 g) L3 with visible pyroxene and calcicNWA 11756 Larger olivine rich asteroid interior specimen with strong visual presence. This brachinite meteorite (NWA 11756) is a rare primitive achondrite, formed through partial melting processes inside early asteroids. Unlike ordinary meteorites, this specimen represents olivine rich material derived from the interior of a differentiated asteroid, offering valuable insight into early planetary formation. Brachinites are among the rarest meteorites
