Fluorite from Spain, Asturias, La Viesca Mine

A beautifully saturated cluster of translucent blue fluorite cubes from the famed La Viesca Mine, Siero, Asturias, Spain — one of the world’s most iconic localities for blue fluorite. The crystals display crisp cubic geometry, glassy luster, and internal zoning that shifts from icy blue to deeper indigo tones depending on the light. Subtle rainbows and internal reflections activate across the faces, giving the piece a luminous, ethereal quality. The largest cube measures 2.94cm.

The fluorite sits on a contrasting druzy matrix that enhances the color and provides a natural, grounded presentation. Multiple intergrown cubes create depth and dimension, offering strong visual appeal from every angle. This is a refined, highly aesthetic fluorite specimen with excellent clarity, balance, and color — a classic representation of the La Viesca pocket style.
