World-famous for its striking large and colourful golden scalenohedral Calcite crystals, the Elmwood mine at Carthage, Smith County, Tennessee, USA is one of the best-known mineral-producing localities in the whole world with stunning display specimens gracing museum cabinets world-wide. This lovely display specimen features two classic large scalenohedral Calcite crystals diverging out from a small plate of crystallized black Sphalerite. The largest crystal reaches over 9 cm in length and although it does not show an iconic intense golden-coloured tip it is in really excellent condition. The second crystal, is a similar colour but has a small nibble out from one side of the crystal. Nevertheless, it combines with the first crystal to make a dramatic display. With support this makes a really fine crystallized Calcite for display. Ex Martin Kershaw Collection, this piece most likely dates to the 1970s or 1980s.
