  • A rather spectacular specimen of descloizite showing two very different habits on the same specimen. On one side, the crystals are deep-brown and very lustrous, while on the other side the crystals are a lighter brown and larger in size. The piece is capped with iron stained, rounded calcite crystals. The old label that accompanies the specimen identifies the locality as "Grootfontein, S.W.Africa". Beautiful and impressive.
