Dolomite cast after Calcite with Duftite

Dolomite casts after Calcite form delicate yet very beautiful specimens from the Tsumeb mine in Namibia and this miniature is a splendid example. The Dolomite forms a thin shell-like sinuous plate whose underside is finely detailed with the morphology of former Calcite crystals. Both surfaces of the creamy white Dolomite have a silky texture and a beautiful opalescent lustre. Adding to the aesthetic is a rich coverage of deep apple green globular clusters of Duftite to about 1 mm in diameter, covering areas of up to 2.0 x 0.8 cm. An excellent epimorph of Dolomite after Calcite and punctuated by Duftite.
