The big crystals are glassy and softly violet, with blocky, stepped faces, and they stand out clearly against the warm, frosty layer beneath them. It has the presence of a museum piece and rewards a close look from every angle. The metal stand shown in the photos is for display only and is not included.\u003c\/p\u003e\n\u003cp\u003eCalcite is calcium carbonate and one of the most varied minerals on Earth, forming hundreds of crystal shapes. A piece like this records two separate stages of growth: first the dense crust of small crystals formed across the rock, then, later and under different conditions, the larger lavender crystals grew on top of it. This piece comes from the Dundas area near Hamilton, where quarries in dolomitic limestone are known for well-formed calcite crystals, and two-generation pieces with this kind of colour contrast are prized by collectors.\u003c\/p\u003e\n\u003cp\u003eCalcite is soft, at 3 on the Mohs scale, and reacts with acids, so it is best dusted with a soft brush and kept away from water-based cleaners and vinegar.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eChemical Composition:\u003c\/strong\u003e Calcite, CaCO₃\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMohs Hardness:\u003c\/strong\u003e 3\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTreatment:\u003c\/strong\u003e Natural\/None\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQuantity:\u003c\/strong\u003e 1pc\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eWith this product, you will receive the actual piece shown in the photographs.
