This is being sold as an NWA achondrite (possible Eucrite) that is currently being classified.
Official classification and submission for an NWA number is currently in progress.
Preliminary testing has shown:
Here is a brief listing of its contents:
-metal rich eucrite
-Gabbro
-Fine-grained Basalt
-Recrystallized Basalt
-Diogenite
-Melt Clasts
I am offering samples of this at a lower price per gram until official classification has been completed. This is the perfect time to buy a nice sample of a very rare achondrite at a price far below what similar material normally sells for.

Name: Northwest Africa 3140 Classification: Achondrite (Ureilite) Found: April 2004 Location: Northwest Africa
History:
A 750 g dense, broken, greenish-grey stone (one large and several smaller pieces) was purchased in Tagounite from a Moroccan dealer by the Hupes in April 2004.
Classification and mineralogy:
(A. Irving and S. Kuehner, UWS): Mainly olivine with subordinate pigeonite and interstitial metal plus finely granular carbon phases (including diamond, judging from difficulties in cutting this specimen). The rims of grains of both olivine and pigeonite exhibit characteristic reduced compositions against interstitial matrix.
