Calcite on Calcite on Dolomite

Item Description

Tsumeb is renowned for calcite diversity and quality and this dramatic large combination is certainly one of the most unusual and exotic you will see. A striking and sculptural, translucent 2-sided "frill" of two generations of calcite rests on a crust of dolomite pseudomorphs after flattened calcite disks. The front of the calcite "frill" looks incredibly carved (more pseudomorphs?) and you can see a few scattered latter generation glassy, tan calcite rhombs. The back of the frill is decidedly different, as it is 100% glassy calcite rhombs! Most of the dolomite crust here is also covered with these calcites. Complete all-around and in great shape. The left side of carved face of the frill has periphery wear, otherwise the piece is essentially pristine. Truly a surreal and excellent calcite combination from this famed locale. From an East Coast collection and comes with a Zweibel Mineral Kingdom of Woodmere label dating from 1973-1780. Value of such an exotic and rare style combination calcite??
