Summary

[edit]
Description
English: Ettringite, Oyelite
Locality: N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa (Locality at mindat.org)
Size: 13.7 x 7.5 x 7 cm.
One of the larger good matrix specimens, this is a beautiful matrix piece, rare for the species, with a 3-dimensional cluster of crystals perfectly centered on matrix. Very aesthetic. The crystals are to 3.2 cm long and the cluster overall is 5.2 cm across. All are starkly contrasting against a rolling carpet of soft white Oyelite. The crystals are a soft, lemon-yellow color, translucent, completely formed and free of damage. They have an unusual shimmering surface sheen, very attractive. The matrix is a manganese-rich ore completely covered on the front by a blanket of soft Oyelite deposition on its front side. It is covered on the backside with a brilliantly sparkling carpet of thousands of micro-hausmannite crystals and a few little metallic hematites. This combination overall is vastly different from anything else I have seen for the species, and quite unusual in any case.
