Bultfonteinite



Bultfonteinite
Bultfonteinite, originally dutoitspanite, is a pink to colorless mineral with chemical formula Ca2SiO2(OH,F)4   Wikipedia

This sample it from Nchwaning Mine, Kalahari M. F., 
R.S.A.  The location is Republic Of South Africa.  I feel certain the "m and f" after Kalahari means manganese fields.

Bultfonteinite
The image at the top is FOV 4.25mm and 5.53x on the sensor.  The second image is FOV 3.577mm and 6.58x on the sensor.

Bultfonteinite
The FOV for the third image is 4.17mm and 5.53x on the sensor.

I don't suppose I would have guessed that crystals form in bundles like these do.  Later, we will look a more crystals which form in an elongated fashion.
