Specimen very rich in mimetite crystals, with shapes of the hexagonal dipyramid, some doubly terminated, with a slightly orange-yellow colour, very brilliant. They are disposed on a matrix of goethite with hemimorphite. From an unusual locality for the species. The specimen has been analyzed since it was labeled as pyromorphite. We will send the results to the buyer.

Wulfenite specimens like the one we present are very unusual for this locality and appeared many years ago. On a matrix with dolomite, galena and baryte there are numerous crystals of intense orange color, with dipyramid faces truncated by the pinacoids. Some appear as isolated crystals and mostly in parallel growth. This specimen is from the Peter Seroka collection and previously belonged to the Marcus Lueg collection.

Size: 7.9 x 7.2 x 4.8 cm.
Main crystal: 1.1 cm.

These specimens of malachite present mamelonar, botryoidal to stalactic growths, with a very intense characteristic green color and silky luster. If they are observed under magnification, they show us that the sparkly green is produced by small malachite crystals that cover the surface. The photograph does not reflect all the splendor and brilliance of the piece. They are disposed on a fibrous malachite matrix. Very aesthetic.

Rare and good sized mangan-diaspore (diaspore with manganese) specimen showing brilliant, transparent to translucent, burgundy red tabular crystals disposed in an arc on matrix. We can also observe small geodes full of crystals. The Glosam Mine specimens are the only ones in the Kalahari area in which the manganese diaspore shows this intense color and brilliance. An exceptional specimen for a little-seen species.

Size: 10.2 x 8 x 6.2 cm.
Main crystal: 12 mm.

Very esthetic specimen of celestine from Morocco. It shows us a large group of prismatic crystals of this strontium sulphate, very well defined and faceted, and with an excellent transparence that allows us to see a soft bluish color. They are disposed on a compact matrix. This locality is northeast of Imilchil town.
