Not pristine but very impressive! The artisanal Yellow Vein, which is actually a thick lense rather than an actual continuous vein, is located near the old Valzergues fluor mine and was never mined for ore. It has however been known since the 1960's for outstanding large fluorite pockets, sometimes up to a dozen meters long and featuring walls lined with large cubes. Unfortunately, most of the crystals in these pockets actually show a poor quality, with dull and etched surfaces due to the acidic decomposition of pyrite: as a consequence, a small 1-5% of the recovered crystals meet the collection standards and as usual, within this percentage, a very small fraction actually represents fine fluorite specimens showing the iconic yellow core and blue zoning stripes. The best finds were made occasionally from the 1980's to 2010's and were source for almost all the classic Valzergues fluorite specimens. Largest crystal: 10.2 cm
