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.

In the first one the aggregate is more spherical and of deeper color. The second, external, phase has a lighter color and it is possible to see the crystal faces. The color of the growths between orange and yellow is different from the older pieces, classified then as Poldervaartite.

TM96N2: 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.

EB54E8: This one stands out for the crystalline terminations, pyramidal and in complex groups that give it a spherical look, and the sharpness of the forms of the prismatic faces. Both the color and brilliance are magnificent. The position of the group on the matrix makes it very esthetic and adds the definitive touch.

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.
