Nice large piece measuring 57 mm by 40 mm by 35 mm, covered in olivine crystals. This one was mostly
 buried, so not as much nice patina, would be a great cutter which is likely what I will do with it.

Specimen weight: 137 grams. SOLD

This fantastic specimen was on the surface, with the top being nicely sandblasted and having a gorgeous natural patina, and the bottom side showing a large olivine crystal measuring over 35 mm long. The white areas in the photos are caliche, rings of limestone, where the specimen was sitting in the soil. It can be removed, but I prefer them natural, that is up to the buyer. This is one of my favorite pieces.
