A classic, old-time, cabinet specimen of yellow fluorite crystals accented with bladed, brown siderite crystals from the historic mines of Cumbria, England. The glassy, nearly transparent, interpenetrating cubes reach to 2 cm and totally cover the elongate, sculptural specimen. Yellow English fluorites are relatively uncommon compared to purple and green fluorite and this is an large example. Superb purple fluorescence. Ex. Robert Sullivan Collection, an East Coast miner/collector.
