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.
