This specimen features well-formed, glassy fluorite crystals with clear zoning between light blue and saturated purple. The main crystals present a smooth, gemmy surface and good transparency and interesting texture, while small chalcopyrite grains are scattered across the faces, catching light and adding a warm metallic contrast. The association with terminated Quartz enhances contrast and offers an attractive presentation from the front display face. From La Viesca mine — a locality prized for richly colored fluorites with strong color zoning. 3.0 x 3.0 x 2.3 cm
