FANTASTIC reticulated twins of gemmy Cerussite. The longest crystal is 3.2 cm, with a width of 2.1 cm and a thickness of 1.8 cm. The Cerussite has excellent luster and gemminess, and the form is fabulous. The Mottramite adds a wonderful accent to this already incredible piece. There is a bit of contacting, and two chips on one of the crystals, but they do not at all affect the overall aesthetics, which are out of this world. A bargain.
