Comment: Ex. Charlie Key collection. uperb combination piece of the rare and very attractive Bultfonteinite, complemented beautifully by the snow-white Oyelite. The Bultfonteinite is in its classic habit of sharp, delicate acicular balls with superb luster. The largest of these is about .9 cm across. Growing on matrix, the Bultfonteinites are surronded by hundreds, if not thousands, of mm-size Oyelite balls. A very aesthetic, and rare, piece.

Minerals: Bultfonteinite (Ca₂SiO₂(OH,F)₄) Oyelite (Ca₁₀B₂Si₈O_{29 12}(H₂O))
