A pair of very well-formed

the one most desirable phosphate species extant

but this color is simply unheard of

prismatic crystals of Vivianite (some are actually doubly terminated

Augelite included with Jamesonite(?) Metavauxite this is a special CassiteriteThe largest crystal on this specimen is one of the biggest Augelites that I have seen from Bolivia. Its amazingly well formed, sharp, surprisingly lustrous, and DOUBLY TERMINATED! It is associated with a few smaller (but not small by any means) Augelites of similar quality. Interestingly, the crystals are included with an unknown blackish mineral (probably Jamesonite) to create an eye catching two toned effect. This piece was difficult to photograph,
