Several substantial calcite crystals project from the upper section, displaying broad reflective faces, internal veils, and softly frosted areas. Smaller calcite growth continues through the central and lower portions, while fine colorless quartz points emerge from narrow cavities and coat sections of the surrounding matrix.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eScattered pyrite crystals provide contrasting metallic flashes throughout the formation.
