Condition

Purple-violet Fluorite crystals are richly clustered over a grey-green bed of micro-crystallised Chlorite from the famous Trevaunance mine at St. Agnes in Cornwall. The Fluorite crystals measure to 9 mm and display shallow, tetrahexahedral crystal faces, a well-known characteristic crystal habit from this mine. In the older literature, this habit was referred to as a ‘four-faced cube’. The Chlorite, more specifically, one of the Chlorite Group species, forms a fascinating layer of perfectly developed intergrown lenticular crystals of silver-grey with an almost metallic lustre. A fine example of tetrahexahedral Fluorite from Trevaunance with the previous collector’s label.
