Bultfonteinite

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.

Bultfonteinite with Hydroxyapophyllite-(K) and Calcite.

EC63R1: Fanlike groups of snowy white acicular crystals of Bultfonteinite replacing the faces of short elongated crystals of Hydroxyapophyllite-(K) which has a pseudocubic habit. In some cases the replacement is deeper and forms a more or less complete pseudomorph of the preexisting Hydroxyapophyllite-(K). All are on a matrix of clear, complex, crystals of Calcite. We’ll send a copy of the analysis to the buyer of the piece.

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.
