Specimen is little oriented in my opinion (hard to show it on photos but
have a good shape).
Texture is typical for monomict ureilite, triple junctions, vein like
area filled by graphite and diamonds, shocked stage is low, in cut
surface You can see dark coarsely grained texture with mm sized olivines
and pyroxene. Size of specimen is : 145x120x85mm, piece looks better in
hand. I found a lot of diamonds using Raman Spectroscopy (not only
typical diamond but also hexagonal diamond - Lonsdaleite).


Any question please send to illaenus at gmail.com
