Namibian Mineral Specimens

   

Namibia has produced many of the finest mineral specimens of the world.  Its mines have created a steady flow of numerous species both rare and common.  Great specimens from these mines have always been available but are normally expensive due to their importance and popularity.

 

 

                    Impressive blue aquamarine crystals from somewhere other that Pakistan. These are aesthetic, gemmy, high luster mineral specimens both on and off matrix from the Erongo Mountains of Namibia.        Aquamarines and Other Minerals form Erongo Mountain, Namibia

Nancy Collins Collection circ. 1970.  This fine specimen measures 8 x 7.2 x 4.5 cm overall and is composed of numerous twinned and untwined cerussites on a lush carpet of forest green malachite pseudomorphs after azurite.  The malachite pseudo are present in two generations: the first generation crystals are large, to 2.7 cm each, and followed by the second generation, much smaller, deeper green pseudos which coat about 30% of the surfaces of the first generation crystals.  On this matrix can be found 2 fine clusters of twinned cerussites to 1.8 cm each and one lonely untwined crystal.  They all stand off the malachite in high relief.  The cerussites are very translucent and have a waxy to silky luster.  There is no damage to the primary display face although some of the edge contacts are visible from the front yet not distracting.  The backside has some mineralization ,as well.  The specimens of malachite after azurite from this mine are known world over as classics.  I’ve sold and seen many dozens of these malachites after azurite, but the several of these I now have for sale are the only ones I’ve known of in combination with the cerussites.  Comes with a custom engraved acrylic base.  Very rare and desirable.   $3,500

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