Summary

Description
English: Ettringite, Oyelite

Size: small cabinet, 7.7 x 5.2 x 4 cm
Ettringite on Oyelite
A beautiful matrix piece, rare for the species, with a pinwheel-shaped, 3-dimensional cluster of crystals perfectly centered on matrix. Very aesthetic! They are to 2.5 cm long, starkly contrasting against a rolling carpet of soft white Oyelite (perhaps with Bultfonteinite). The crystals are a pastel almost-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 with a blanket of soft Oyelite (perhaps with Bultfonteinite) deposition on its front side. It is covered on the backside with sparkling micro-hausmannite crystals.
