A 369.5g stone was purchased out of Morocco in August of 2013. I cut and prepared several initial slices myself and classification was done by Dr. Anthony Irving, who determined the stone to be a ureilite. Slices were cut thin to reduce price and allow for a great surface area. As the slices are rotated they have a holographic appearance with some slices have spots of golden translucency when held up to light. THE PICTURES DO NOT DO THIS STONE JUSTICE! It is beautiful and sparkly in the light which cannot be duplicated on paper (…or screen). Each slices comes in a quality labeled meteorite display box.
Petrography as follows (updated 01/27/14 due to typo):
Protogranular aggregate of zoned olivine and pigeonite (Fs13.0-13.4Wo7.3-7.4). Olivine cores have a mean composition of Fa16.0 (Cr2O3 = 0.8 wt.%); rims are much more magnesian (Fa2.5; Cr2O3 = 0.7 wt.%) and contain fine inclusions of iron metal.
