Ferroan Dolomite with Calcite

Item Description

Mineral specimens from this obscure underground mine near Tucson are rarely available. The Reward (Vekol) Mine was discovered in 1879 and produced intermittently until 1965. Highly lustrous, Hematite-included (ferroan), rust-red Dolomite rhombs cover the sculptural crust of nearly solid Dolomite. The matrix Dolomites average .5-.7 cm, while the large Dolomite rhomb sitting on top is an outstanding 2 cm in length. This is an excellent and showy specimen from this very uncommon Arizona locale. The hundreds of mm-size, gemmy Calcites add a nice finishing touch.
