Calcite with Pyrite, Chalcopyrite, Goethite & Limonite – Breathtaking Red & Violet UV Fluorescence with Phosphorescent Afterglow – Daye Mine, China

A truly spectacular multi-mineral specimen from the renowned Daye Mine in Hubei Province, China — and one that must be seen under ultraviolet light to be fully appreciated.

In natural light, this substantial piece displays layered calcite formations accompanied by pyrite, chalcopyrite, goethite, and limonite, with contrasting cream, gray, brown, and subtle metallic tones that reveal new textures from every angle.

Under ultraviolet light, the transformation is breathtaking. The specimen erupts in deep crimson reds and rich violet-blues across its surface — an almost nebula-like display that dramatically contrasts with its natural-light appearance. When the UV light is switched off, a lingering phosphorescent afterglow continues to radiate, making the experience even more mesmerizing.
