Calcite, Quartz
Cabinet, 9.9 x 6.4 x 6.1 cm
Droujba (Drujba) Mine, Djurkovo Complex, Laki (Luki), Rhodope Mts, Plovdiv Oblast, Bulgaria
A very weird and interesting Eastern European specimen of calcite crystals intermixed with quartz, with both pseudomorphing occurring and the calcite being etched away on many crystals to form hollow casts. You can really study this one for a long time without getting bored! 9.9 x 6.4 x 6.1cm
