Fluorite from Spain, Asturias, La Viesca Mine

A beautiful fluorite cluster from the La Viesca Mine in the Siero district of Asturias, Spain — one of the most iconic fluorite localities in the world. This specimen displays the classic La Viesca aesthetic: sharp, well‑formed cubic crystals in soft purple tones, perched on a pale, contrasting matrix. What makes this piece especially appealing is that crystals are present on both sides of the specimen, giving it a dynamic, multi‑angle display. Several cubes show internal rainbow flashes when the light hits just right, adding depth and color to the already luminous fluorite.

The matrix is typical of La Viesca material, providing a clean backdrop that enhances the clarity and geometry of the cubes. Whether displayed flat or upright, this piece offers strong visual interest and excellent locality character. A refined, collectible example from one of Spain’s most sought‑after fluorite mines.
