An attractive calcite specimen with hematite inclusions from the Giudurska Mine, Erma Reka, Smolyan Province, Bulgaria. This specimen comes from Steve Potvin's impressive calcite collection and is believed to have been mined over 40 years ago.
The specimen features an extensive arrangement of delicate, overlapping calcite crystals in distinctive "poker chip" formations. The crystals display soft salmon-pink to peach coloration attributed to hematite inclusions, with translucent edges and a subtle pearly to vitreous sheen. Numerous flattened, layered crystals form rounded stacks and rosette-like groups across the matrix, creating a richly textured, three-dimensional surface.
The abundance of well-developed poker chip formations gives this specimen a particularly appealing sculptural appearance, while the gentle pink coloration adds to its visual character. Its combination of unusual crystal forms, attractive colour, historic Bulgarian mining locality and documented Steve Potvin provenance makes it a distinctive cabinet specimen for collectors of calcite and European minerals.
