A superb, large plate of slender, gemmy quartz crystals that look much like amethyst due to their heavy inclusions of the iron-based mineral lepidocrosite. However, they should be called amethystine because the color is not due to the same reasons as the purple in amethyst. The lepidocrocite was deposited on the quartz crystals as they grew, and engulfed as the crystals continued their growth, so that now you can see the lepidocrocite deep inside each individual crystal. Not only interesting, but really beautiful! 11.5 x 9.5 x 4.7 cm
