Fluorite with Sulphide inclusions

A fine small cabinet specimen of Fluorite from Ladywash mine at Eyam in Derbyshire, England. Intergrown colourless Fluorite crystals tinged smoky yellow, measuring to 2.4 cm richly adorn a matrix of massive cryptocrystalline Fluorite. The Fluorite crystals reveal two separate phases of iron sulphide inclusions. Under magnification, a deeper zone shows pale yellow-white metallic micro-crystals of bladed Marcasite, while a near-surface zone contains micro-crystals of Pyrite. Ladywash mine is well known for its sulphide inclusions in Fluorite which are a true Derbyshire classic. The specimen is accompanied with four labels, three of which are quite famous names in the world of mineral collecting.
