Petal-shaped white calcite. salmon-pink fluorescence - Height: 140 mm - Width: 75 mm- 476 g - (1)

White calcite is a common carbonate mineral known for its array of crystal forms and often gentle coloration. This particular specimen is shaped like a delicate petal and displays an intriguing salmon-pink fluorescence under ultraviolet light, which is a unique characteristic of some calcite varieties. Calcite's rhombohedral cleavage and relatively soft nature make it prevalent in sedimentary environments and a favorite among collectors for its diverse morphologies and optical properties. Fluorescence in minerals occurs due to impurities or structural defects, and in calcite, colors can vary widely, sometimes glowing in vivid pinks, blues, or reds. This petal-shaped calcite offers both aesthetic appeal and an educational glimpse into mineral luminescence phenomena.
