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.

Bultfonteinite is a rare phyllosilicate (calcium fluorsilicate) that exists in the N'Chwaning mine along with another rare phyllosilicate (also calcium), Oyelite. In fact, while awaiting the analysis of these specimens we had indicated on the web site that they were Oyelite, as previous finds from the same mine with the same appearance and white color had always been considered Oyelite. So when we got the results of the analysis, much to our surprise, the fluor present in the sample as well as the atomic ratio of Ca/Si=1:2 indicates that the specimens are Bultfonteinite and not Oyelite.

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.
