This calcite from Gongcheng, China is really different – it is from an unusual locality for such calcite (to date) and shows excellent different morphology for calcite. The first thing to grow was a yellowish crystal at the base, which now forms the core, and that crystal itself is hollow up its centre. The main pair of calcite crystals show a termination morphology more typical of quartz, not unlike the calcites from the Dachang Mine, Nandan. These two are in fact doubly terminated and also exhibit growth phantoms. The specimen is then host to many smaller crystals of similar quartz-like habit. There is a spot of damage to one corner of one of the main crystals – this would either be displayed so that is is around to the back or alternatively facing down (it is the corner at the bottom centre in the last photo). The crystals are sharp and lustrous – super calcite!
