A beautiful matrix piece, rare for the species, with 5 crystals to 3 cm perched against a rolling carpet of soft white matrix. The crystals are a soft, almost-lemon-yellow color, translucent, completely formed and free of damage. They have an unusual shimmering surface sheen, 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.
