Summary[edit]

Description
English: Baryte, Ettringite, Oyelite
Locality: N'Chwaning I Mine, N'Chwaning Mines, Kuruman, Kalahari manganese fields, Northern Cape Province, South Africa (Locality at mindat.org)
Size: cabinet, 13 x 10 x 5 cm
Ettringite on Oyelite with Barite
This large matrix cabinet piece features a perfectly situated , doubly-terminated, 5-cm-long crystal perched atop. It is uncanny, how it just hangs there so fully exposed, as if placed gently down, and now anchored by the soft Oyelite and showing both terminations. The crystal is a soft lemon-yellow color, translucent, and complete all around. The matrix is gorgeous and unusual: This is a VERY heavy specimen, as the rolling carpet of soft Oyelite hides a hematite-rich matrix underneath. On the backside , it is nearly covered with sharp bladed barite crystals atop the hematite, unusual for this locality.
