SOLD Lueshite - single crystal, type locality
stock #SOLD 21.1-521
Lueshe Mine, Bwito, Rutshuru Territory
North Kivu Province, Democratic Republic of Congo (Zaire)
7 x 7 x 5.5 MM (thumbnail)
price: $0


A somewhat sharp complete single cube of the rare earth specie Lueshite from the type locality. This Sodium-Niobium mineral is not often available, the metallic black to silvery color is typical of crystals from here, and the size is above average. This crystal has rough spots on some edges as seen but is overall in good shape, a nice crystal of this rare specie.

Shattuckite and Plancheite after Anhydrite
stock #AX-19-185
M Sessa Mine, Katanga Copper Crescent
Katanga (Shaba), Democratic Republic of Congo (Zaire)
4.4 x 1.5 x 1.4 CM (miniature)
price: $700


A remarkable and unusual secondary Copper piece; a hollow cast that shows the form of the original Anhydrite crystal that was replaced by bright blue Shattuckite. The Shattuckite is covered with a mint green layer of Plancheite making a nice contrast. The whole piece has the form of the original Anhydrite crystal and maintains a central void with the same shape. Reminiscent of the shape of Azurite casts from the Apex Mine in Utah, this is an even more rare replacement found just once about 20 years ago at the M'sessa Mine of the Katanga Copper Crescent.

Cuprite on Chrysocolla
stock #AX-19-263
Mashaba West Mine, Kolwezi Mining District
Lualaba Province, Democratic Republic of Congo (Zaire)
5.1 x 4.1 x 3.8 CM (small cabinet/large miniature)
price: $580
Early summer 2021

Perfect and with fine form, dark red Cuprite crystals are perched on contrasting blue-green Chryosocolla. Modern classics, good Cuprites from this region are highly regarded. These crystals, besides being damage-free, are also gemmy, with any backlight they glow a ruby red color. The photos here are made with normal lighting to give a fair idea of the specimen without extra enhancing illumination. We have seen many specimens from this locality but very few are so perfect. The octahedral crystals here show both twinning and some elongation. An older piece, (we believe from the 1970-80 era), with several earlier labels from previous collections, including Paul Jung, James Lewis, Greg Kirby. This is certainly a choice specimen far beyond average quality.

Barite with Malachite inclusions
stock #21.FC-023
Shangulowe Mine, Kambove District
Lualaba Province, Democratic Republic of Congo (Zaire)
5.1 x 4 x 1.5 CM (small cabinet/ large miniature)
price: $560
Early summer 2021

A fine example of the rare "green Barite" from the Shangulowe Mine (Kabove, DR Congo). This has a main crystal that is over 4 CM across which is huge for this find. The clarity and condition are excellent and the whole displays very well on the contrasting matrix. The brightest green zones are more concentrated on the edges and the overall color is a bluish grey-green. In excellent condition there is no damage to the Barites which at this size is remarkable.

Malachite - Crystals and Botryoidal forms
stock #10.1-500
Katanga, Central Area, Katanga Copper zone
Shaba, Democratic Republic of Congo (Zaire)
8.3 x 6.2 x 4.3 CM (cabinet)
price: $280
Early summer 2021

A classic from Katanga, this is a two sided specimen. One side is composed of sharp radiating fibrous crystals topped by a pair of Malachite balls. The other side is all botryoidal with some distinct chatoyance caused by the balls being composed of fibrous crystals. Excellent condition, color, form and luster. The Shaba Crescent was the source of much outstanding Malachite and these are still very reasonably priced, one of the mineral world's best bargains. In person the color is a bit deeper, darker and the shimmering luster is almost impossible to appreciate in a photo.

Cornetite with Malachite
stock #20.1-875
L Etoile du Congo Mine, Lubumbashi
Haut- Katanga, Democratic Republic of Congo (Zaire)
7.2 x 4.7 x 2.3 CM (cabinet)
price: $45
new year 2021

A powder blue crust of tiny Cornetite crystals mixed with some Malachite on matrix. This is sawn on the back but the front is all natural. An affordable example of this rather rare Copper mineral.

Dioptase with minor Calcite
stock #6.2-923
Tantara Mine, Shinkolobwe, Kambove District
Haut- Katanga, Democratic Republic of Congo (Zaire)
6.2 x 5 x 4.3 CM (cabinet)
price: $800
new year 2021

Brilliant gemmy Dioptase crystals with intense emerald green color cover the face of the matrix. From the Haut Katanga area of the D.R.Congo, this fine older specimen has the top luster and color more like that sought after in Tsumeb specimens. More recent Dioptase finds tended to be more matte luster or had stepped faces, with much less flash. This is great for the locality and a classy Dioptase from any place. The crystals are very well-defined and reach 1.3 CM. In person this is a strong display specimen with color that is impossible to appreciate on a computer screen. Overall in very good condition, there is some chipping at the outer edges but most of the important crystals are perfect and the display impact is not diminished.

Plancheite
stock #20.1-823
Mindingi Mine, Kambove District
Haut- Katanga, Democratic Republic of Congo (Zaire)
7.3 x 5.2 x 4.1 CM (cabinet)
price: $290
new year 2021

A sizable mass of radiating fibrous crystals of Plancheite on matrix. The Plancheite specimens from the Congo are remarkably rich, considered by many the worlds best come from the Katanga region. This specimen is from an old find at the less well-known Mindingi Mine in Kambove. It is similar to other good specimens from the region and has the silky to chatoyant luster that is distinctive for the specie. Most often Plancheite is seen as an associate mineral, being the matrix for other Copper species, but it can be a very attractive specie in its own right. This looks especially impressive under magnification.
