This specimen features bright green orthorhombic prisms of zincolivenite. The focal point of the piece is the central mound of crystals, while the larger individual crystals (up to 0.5 cm) surround it. In excellent condition, with incomplete crystals at the periphery where the piece was attached. Once a Crystal Classic specimen, the label accompanies it. […]

This specimen features blocky, barrel-shaped mimetite crystals up to 0.9 cm perched on a bed of sharp smithsonite crystals. The mimetite crystals are well-defined with lustrous prism faces (with some mottled colouring), and complex sugary terminations. In excellent condition, with no damage to the key mimetites – a couple of small incomplete crystals on the […]

Mimetite is one of the signature minerals from Tsumeb, and this specimen is an aesthetic presentation of vibrantly-coloured sprays of mimetite crystals. With magnification, these crystal sprays have nice definition and are lustrous with good sparkle. In excellent condition, with a few incomplete  crystals around the edges. Formerly a Crystal Classics specimen, with label included. […]

This specimen features beautiful lemon-yellow mimetite crystals. The crystals are sharp and lustrous, with bright pyramidal terminations. As displayed (as photographed), in very good condition, with minor rubs and some incomplete crystals. A classic, very well crystallized Tsumeb mimetite! The video is great for the lustre and 3-D nature of the specimen, but the photos […]

A cluster of wonderful sharp, lustrous hexagonal mimetite crystals from Tsumeb. The crystals are colour-zoned, with deep golden-yellow in the centres and lighter yellow at the terminations. In excellent condition. This specimen was in the collection of Tracy Kimmel, ex. Mandy McAvoy. An absolutely super thumbnail of Tsumeb mimetite! About Tracy Kimmel Please Note: the […]

This piece features incredibly sharp, glassy anglesite crystals, the largest of which is 2.7 cm. The crystals at the top of the specimen stand up over the matrix – the larger of the two is translucent and the smaller is transparent. In excellent condition as I would display it (as in these photos) with one […]

Dioptase is one of the most sought-after species from Tsumeb, and Tsumeb dioptase is often referred to as the best of species, in part because of sharpness, lustre and top colour, but also due to the translucency and transparency (giving life to these specimens under the lights), and in addition, in some cases the contrast […]

This specimen features a cascade of gorgeous lustrous wulfenite crystals tumbling down the middle of the dark matrix. These crystals are brilliant – I don’t think I have ever seen wulfenite with brighter lustre. Exhibiting wonderful form, these wulfenite crystals show predominant pyramidal faces and small square terminal faces. Their exact colour is hard to […]

Detailed Description This is a fine pseudomorph of goethite after marcasite, with well-defined crystals all around – lustrous and a very dark brown, virtually black. Of the many habits of these White Desert pseudomorphs, my friend Tracy Kimmel used to call this the “mace head” habit. In excellent condition and with good lustre, as the […]

Of the many habits of these White Desert pseudomorphs, my friend Tracy Kimmel used to call this the “mace head” habit. In excellent condition, a couple of chips that are […]

Detailed Description This pseudomorph of goethite after marcasite has a cool habit we see in a few specimens, where there is an appearance of an overall pseudo-octahedral shape – and in this case, two. This piece also features  small, rounded aggregates of cuboctahedral pyrite pseudomorphs, perched on the marcasite pseudomorphs.  It is very brown, virtually […]

Detailed Description This pseudomorph of goethite after pyrite, with three main compound-growth cubes. It is dark brown  and the crystals are moderately lustrous, polished by the blowing sands of the White Desert. The crystals show oonly very minor rounding from the natural sand polishing. In excellent condition and complete all around. A very fine White […]
