BlueJohn
To see this picture of Blue John please open tin your browser. Calcium Fluorite with a bit of calcium carbonate, calcite, thrown it. I was lucky enough to visit the High Peaks recently and to go to Treak Cliff Cavern. This mineral much prised for it's decorative properties is only found here and this site is the only place in the world where you can find veins of it still in the rock. The surrounding stuff is carboniferous limestone but about 200 million years ago these veins formed. Wonderfull cave too.
