Grateful Dead Calcite UV Reactive

Stunning Grateful Dead Calcite from Mexico. Measures 4” x 4” and weighs .935 lbs. (423 grams).

The term “Grateful Dead Calcite” refers to UV‑reactive calcite–aragonite specimens from the Ojuela Mine in Mapimí, Durango, Mexico. Under longwave UV (365 nm), they glow in intense greens and reds, sometimes with additional orange or yellow tones. This psychedelic color palette is what earned them the nickname “Grateful Dead” calcite — a nod to the band’s trippy, multicolored aesthetic.
