A lustrous particularly well formed inter grown crystal group of Fluorite from the Tincroft Mine, Illogan, Cornwall. The crystals of Fluorite measuring to 2cm display well developed cubic faces truncated by the tetrahexahedron. A fine gemmy sea green colour is seen to the Fluorite crystals, with an internal band of purple. Milky white prismatic crystals of Quartz measuring to 2cm are in association. An excellent Cornish Fluorite from the Tincroft Mine.
