The yellow fluorite cubes from the Hilton Mine have always been among the favorite specimens from the Midlands of England, and are very rare compared to the green and purple crystals which come out of many other mines while these typically come form jsut the old Hilton mine. This particular matrix specimen features several penetration-twinned, gemmy, yellow, fluorite cubes to 1.75 cm across, that are perched on smaller cubes of fluorite. The specimen fluoresces a rich lavender color. Very nice!
