OKA-852

OKA-852 Fluorite Okorusu, Namibia, Africa. This is the quality material found in the 1950¹s. I acquired 6 specimens one of which I will describe here. All are between 50$ and 120$, about the same size, but they vary in there crystal size and aesthetics. They are not cheap for fluorites but it is unlikely that we will see any more of this material, so I anticipate that all these will sell rather quickly. This dome of crystals to 2 cm each is 6 x 5 x 4 cm overall. Wonderful combination of greens and purples. Hard to tell but it almost looks like purple over octahedral greens. Very unusual and tough to describe. A couple very tiny dings on one of the crystals. These would be a must for the serious fluorite collector.  80$
