Wulfenites have always had broad appeal as a species, and those from Tsumeb a particular fascination. These Wulfies have great luster and a complex habit, and the color is more yellow and vivid than most. Quite attractive in their own right, the Wulfenites even rest on a white Calcite matrix that has an intense, orange fluorescence. These butterscotch crystals are special! Ranging up to about 1.7 cm, the Wulfenites add to a rich and aesthetic combination piece for Tsumeb. Previous labels indicate J Immelmann collection at 2550 British Pounds.
