When mining theseores, quartz, calcite, dolomite and fluorite are discharged as waste as it is absolutely essential to enrich the economically usable (metal) component. A unique environment of formation of fluorite-rich veins near W\u00F6lsendorf in south-east Germany offered an exceptional opportunity to use the value of that waste material - after the treatment of the ore a fraction remained which was rich in deep purple \u201Cfetid\u201D fluorite and it attracted attention by a remarkable accumulation of grains of equal coloring. There are no other central-European locations capable of supplying several years of production of demanded deep purple color shade. No other locations, not even the one in J\u00E1chymov, enabled economical extraction of deep purple fluorite." . "RIV/60461446:52810/10:#0000077!RIV11-MSM-52810___" . "000288141200015" .
