This amethyst rosette is a uniform, pastel lilac color, with good translucence and luster. The largest crystal is 2.0 cm in length. Enhancing this piece is a dusting of iridescent, pyrite crystals which average .1 cm across. The color of this amethyst is very close to the color of amethyst and pyrargyrite which appeared in Peter Bancroft's first book and which proudly resides in the British Museum of Natural History, from Guanajuato.
