Description

There is a HUGE Manganoan Calcite crystal of first generation and with uncommon strong saturation (for Dal´negrosk). The crystal is formed like a bone or a club. It is partly covered with tiny Calcites of second generation, they are lighter and - like the large one - highly lustrous. This giant crystal is resting on a thin stipe of greenish matrix. The Calcite is complete all around, you can see front-display and side-view on my images to give you a  better idea of this stunning assemble. Pure aesthetics and fine quality in union with impressive dimension. Undamaged
