Fluorite - an optical and practical challenge
Below are high resolution animated renditions of Fluorite designs shown in an article to be published in the UK Facet Cutters' Guild's magazine, Faceters' Stonechat. The same hue, saturation and transparency have been used for all. In the near future these images will be replaced by those reflecting the remarkable properties of gem quality Fluorite currently being produced by UK Mining Ventures (http://www.ukminingventures.com) from their Rogerley and Diana Maria mines at Frosterley, Weardale, County Durham.
