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.
L'Etoile du Congo Mine (Star of the Congo Mine), Lubumbashi (Elizabethville), Katanga Copper Crescent, Katanga (Shaba)  Congo DR (Zaire)

Specimen size: 8.9 × 6.3 × 3 cm = 3.5” × 2.5” × 1.2”

Main crystal size: 0.6 × 0.5 cm = 0.2” × 0.2”

Cuprite with Calcite

TB17E6: These crystals of Cuprite have a very metallic luster, but are not that red. That said, the definition and form are, in my opinion, good, so overall it is a neat specimen.
Mashamba West Mine, Kolwezi District, Katanga Copper Crescent, Katanga (Shaba)  Congo DR (Zaire)

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 (George Burnham) and from D.E. Boydston collection.

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.

TA62F3: A crystallographic rarity. The crystal is almost exclusively formed by the faces of at least three pyramids, while the prism is almost inexistent. One side is covered with Muscovite, which contrasts well with the deep blue-green of the Beryl. This all makes for a strongly esthetic specimen whose base is formed by the surfaces of its contact with the pocket.

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.

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.

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.

EM63T0: A crystal with very well defined faces and edges, transparent, very bright and with a doubly terminated crystal. The color is especially intense and, due to some details, we believe it is natural, not induced by heating. The "fresh" appearance of related Prehnite crystal, with some white areas that must change color when heated, and the grayish shades at the bottom of the piece, that must also turned to blue-violet, are reasons why we offer this sample as natural, not heated.

This sample was collected by K. J. Reid in November, 1976, who published an interesting article on The Mineralogical Record (Vol. 9 n. 6, Nov.-Dec. 1978).

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.

Olmiite

From the great Olmiite finds made in N'Chwaning Mine 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.

EQ99: Excellent color, perfection, and esthetic: the form is really nice, it looks like a snowman. A exclusive and funny thing.

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.

EN27C2: Yellowish under spot light, but the three doubly terminated wheatsheaves so well placed on their matrix that we thought that some customer would fall in love with it.

TP47N2: A novelty of Tucson 2009. Unusual groups of crystals of irregular contour, more or less oval-shaped. They are pink, and more intense on the terminations. They are on very acute scalenohedrons of Calcite and on matrix. They have come from a single geode. At first we believed they could be Poldervaartite due to the presence of the accompanying Calcite and the pinkish color of the crystals, but the analysis confirms that they are Olmiite (the manganoan end of the series) and not Poldervaartite (the calcian end). We’ll send a copy of the analysis to the buyer of the sample.

EB2B9: Two photos showing its spectacular color change. Just minor matrix on its rear, almost a floater specimen complete in all sides with perfect form and excellent luster-color perfection. The crystals have a spherical form, they are gemmy and are formed by hundreds of small parallel grow crystals. A beauty!.
This specimen was photographed for the magazine ‘Mineralien Welt’ and appears on page 18 of number 1/2009.
N'Chwaning II Mine, section 5 south, stope 46-47 roof, Kuruman, Kalahari manganese fields  South Africa (01/2002)

Specimen size: 5.5 × 3.7 × 3.2 cm = 2.2” × 1.5” × 1.3”

Fluorescent long & short UV

Type locality
Olmiite with Calcite

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.
N'Chwaning II Mine, N'Chwaning mining area, Kuruman, Kalahari manganese field (KMF), Northern Cape Province  South Africa (11/2003)

MA88N6: Globular growths of small crystals of Olmiite whose faces are very well defined and very bright, with two degrees of color, clear cream in some areas and slightly orange in others. On matrix, with small crystals of white Quartz.
N'Chwaning II Mine, 45 level, Kuruman, Kalahari manganese fields, Northern Cape  South Africa (10/2008)

MH31M5: A novelty of Munich 2008. The sample forms globular growths of well defined terminations of crystals. The deeper color is similar to the older pieces, classified then as Poldervaartite.
This specimen was photographed for the ‘what’s new at Munich 2008’ section of the magazine ‘Mineralien Welt’ and appears on page 18 of number 1/2009.
