A great Fluorite from one of Cornwall's best locations for the species, the Wheal Trevaunance, St. Agnes. The single Fluorite crystal sits nicely at the centre of the specimen. It has a delicate light purple colouration and fine lustre, showing a typical stepped growth habit. Associated are Pyrite crystals to 2mm on a dark green Chlorite covering a Killas (country rock) matrix. A fine addition to any collection from Cornwall.
