Outstanding specimen of blue-green fluorite from Le Burc, (Tarn), one of the most renowned fluorite localities in France. This large piece, measuring approximately 19 × 15 × 10 cm, presents sharp, transparent to translucent cubic crystals with internal zoning ranging from pale aqua to saturated blue-green, characteristic of the finest Burc material. The cubes show excellent geometry and luster, with several faces displaying a subtle silky sheen under strong light. The contrast with the beige matrix enhances the aesthetic quality of the piece, giving it strong visual impact from multiple angles. A specimen of this size, clarity and color intensity from Burc is increasingly rare on the market, as the locality is long closed. Origin: Burc, Tarn, Occitanie, France Mineral: Fluorite on matrix Dimensions: approx. 19 × 15 × 10 cm Condition: Very good overall; natural piece with no restoration Notes: Photographed under natural and directional light; colors may vary slightly depending on screen settings.
