Black Chocolate Calcite Specimen – Strong Orange UV Fluorescence | Hunan, China (Copy)

This exceptional Black Chocolate Calcite specimen originates from the mineral-rich province of Hunan, China — a world-renowned locality known for producing some of the finest fluorescent calcite in the world. Under white light, this piece displays deep, warm chocolatey-brown tones with a lustrous, waxy surface. But the real magic happens under UV light — it erupts in a vivid, strong orange glow that makes it a showstopper in any UV mineral collection.

Calcite is one of the most common minerals on Earth, yet this variety stands apart for its rare dark coloration and intense fluorescent response. The orange fluorescence is caused by trace activators within the crystal lattice, and the intensity of this specimen's reaction is notably strong — visible under both shortwave and longwave UV.

This is a display-ready, cabinet-quality piece — solid, well-formed, and requiring no cleaning or preparation. It sits stably on a flat surface and presents beautifully from multiple angles.
