Calcite from Gyudyurska mine, Smolyan Province, Bulgaria

A very attractive specimen of manganocalcite, composed of delicate, pale pink feather-like crystals with a distinctive layered and slightly fanned structure, resembling a beautiful pink rose. The specimen is striking not only for its delicate natural pink color, but also for its intense fluorescence under 365 nm UV light, where it takes on a vivid reddish-pink hue. The actual fluorescence is more towards red and cannot be accurately captured in a photograph.
