Item Description

Adorable and uncommon pseudomorph combination miniature from a limited 2010 find at the famous N'Chwaning II Mine. Pale pink fan-like sprays of tiny acicular Bultfonteinite crystals, a rare hydrated silicate with hydrogen and fluorine, have pseudomorphed a dramatically well-placed, 1.6 cm, tetragonal cubic Apophyllite crystal. The pseudo rests on a very sculptural cluster of tiny, intensely sparkly Calcite crystals. Scattered hemispheres of pale pink Bultfonteinite crystals are an outstanding complement to this very fine and aesthetic pseudomorph combination. This cutie looks great from either side. See the fine N'Chwaning Mines article in the 2017 Mineralogical Record issue, Vol. 48, No. 1.
