Kolwezi  Congo D.R.

Specimen size: 7 × 5.6 × 9.3 cm


 
Cornetite with Malachite

E16EDH5: Crystals are very bright and appear in radial groups. Some of these groups are deep uniform marine blue, some others have a clearer blue in zones near the center and are deeper on the edges. We call attention on the contrast with the deep green color of the Malachite base.
Mine de l'Etoile, Shaba, Lubumbashi  Congo D.R.

TX16H7: The main crystal, rising on a surface of smaller crystals, can be considered as a giant. Its faces and edges are perfectly defined, bright and partially pseudomorphed by another (undetermined) copper mineral. The matrix is a very rich blue mineral described as Chrysocolla on the label but it must be Plancheite. Please note that although the original labels state that the locality is "near Gouloukoutou River", we have labeled it as Tantara because we believe that this is the right locality.
The sample is with two old labels, of Burminco (Monrovia, California) and from D.E. Boydston collection.
Tantara Mine, Kakounde, Likasi, Shaba  Congo D.R.

Specimen size: 4.9 × 4 × 3.2 cm

Main crystal size: 2.8 × 1.7 cm


 
Barite with Malachite inclusions

KB92M3: Group of parallel greenish doubly terminated Barite crystals. This greenish tone is caused by Malachite inclusions. On a Limonite matrix. One of the best samples of this shape found in this locality. We consider this specimen among the best Barite with Malachite specimens worldwide.
The specimen is from the James Catmur collection and we’ll send the label to the buyer.

Apophyllite-(KOH)

MZ14D5: The N'Chwaning Mine is famous for its fine Rhodos but it also produces curious Apophyllite-(KOH) specimens which are totally different from the Indian ones or any others for that matter. This esthetic group perched on its matrix displays very well due the extremely aerial position of the crystals.

Malachite after Cuprite
Malachite after Cuprite.

TX96D8: From old discoveries comes this Cuprite that has been psuedomorphised by Malachite. The piece is a floater, the crystal is well defined, and it has a form that is different from the typical ones. It also has the virtue of being on matrix, something that is not usual in material from this mine. A special classic specimen.
Onganja, Seeis, Windhoek  Namibia

Specimen size: 2.5 × 2.2 × 1.7 cm


 
Actinolite

TB88: A Namibian novelty: in one area of the Namibian dessert, more or less due West of Uis, people found new Actinolites, very sharp and with a slight green tint, making the specimens more agreeable than others that are blacker. We got this specimen, which is a floater and complete on all its sides, for its luster and perfection.

Rutile and Hematite pseudomorph after Ilmenite crystals

Very interesting novelty of 2007 Munich Show: trigonal crystals of Ilmenite transformed into an intimate intergrowth of Rutile and Hematite. Microscopic examination shows that Rutile (reddish) occurs as a delicate network of needles which are oriented parallel to the basal sections of the former Ilmenite, while Hematite (black) forms the interstices.

Carrollite

Between 2001 and 2003 Congo has given us fabulous Carrollites, which were much better than the older ones. We got hold of many nice specimens that sold well on our web pages. We still run into them when buying from our normal sources and we still see some good specimens which we can offer on our website. Thus we can continue to offer this excellent mineralogical species.

TD13J5: Magnificent crystal, very well defined and bright with an esthetic graded change of color clearer at the base and deeper on the termination with zoning. An important aspect is that it is on matrix, which is very rare with samples from this region. Even it had (badly) been popularized as Brandberg, the true locality is Gobobos, another nearest volcano.
The specimen is from the Charlie Key collection.

Olmiite

From the great Olmiite find made in South Africa we offer this further material. The quality is, as you can see, much better than the Poldervaartites found in the Wessels Mine. Notably the color is much more intense and redder. On the subject of the color it is necessary to warn you that some of these new Olmiites show an intense color change depending of the kind of light used: in day light they become yellowish but in artificial light they are a spectacular strawberry red color.

EG66C0: The form is similar to a wheatsheaf and its good brilliance and color make this little jewel very attractive.

EQ6E8: Two complex crystals placed on their matrix to give a very aerial sample. It stands out for the sharpness of the crystal form, which is prismatic and double–pyramid, which is not that common in Kuruman. While the color is a little less intense than other samples it is compensated for by the intense brilliance, which is due to the large number of flat faces on the crystals.

ME16: Lovely specimen with two complete balls well placed on their matrix, just with two attachment points on the rear. Showing an extremely intense red color under spot light and also a moderate reddish tint to the yellowish color under day light. Definitive, for collectors searching for a major specimen.

TM98D8: Recently new Olmiites were found in N'chwaning. The color is a little more orange than the first ones, and the crystals are a little bit smaller. But these ones are on a matrix of small crystals of gemmy Calcite, making the whole specimen esthetically pleasing. The prices are also lower than they were for the first ones, so we think they are a good deal. In this case the crystals of Poldervaarite are well positioned on the matrix, nicely separated, aerial, and have good contrast with the matrix.

Rhodizite

Madagascar is the major source of Rhodizite, a rare Beryllium Oxide, with Caesium, Potassium and Aluminium. From our friends in this country we got choice specimens that have better color (more greenish and intense) than is usual.

Rhodizite

AA76F3: The dodecahedral crystals are yellow and intensely brilliant. They also have a degree of transparency that is not very common. This one has just the right amount of matrix to give it the perfect esthetic balance.
The specimen has been analyzed and we will send a copy of the analysis to the person that buys it.

Pezzottaite

One of the most interesting novelties during Tucson 2003 was the new species Pezzottaite from Madagascar (a Cesium rich Beryl whose name has already been officially published in the IMA list). Their color is totally different from other Beryl and their chemical composition (CsLiBe2Al2Si6O18) is also different from that of regular Beryl. As usual, knowing how things happen in the mineral world, we purchased the specimens now offered on line. We selected them for their sharp form, good color or especially in the case of the best one for its 'matrix' appearance.

TD37C4: Well, this particular specimen is something special. In this find sadly not many good specimens were found on matrix. Although this specimen is not strictly "on matrix" given its particular form it looks like a matrix specimen. Color quality and geminness are those of the best of the find. The size is good when comparing it with the largest ones. Its price is, in our opinion, reasonable based on the prices for other really good specimens.
