This specimen comes from Steve Potvin's impressive calcite collection and is believed to have been mined over 40 years ago.\u003c\/p\u003e\n\u003cp\u003eThe specimen features an extensive arrangement of \u003cstrong\u003edelicate, overlapping calcite crystals in distinctive \"poker chip\" formations\u003c\/strong\u003e. 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.\u003c\/p\u003e\n\u003cp\u003eThe 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.
