Pollucite is a very rare Cesium bearing Zeolite mineral, and one of the very few facettable Zeolites in the world. Cut stones are extremely rare, and are highly sought after by collectors. Strangely, this Zeolite is most often found in granitic pegmatites as opposed to Igneous deposits like most Zeolites. In recent years, some great gem quality Pollucites have been coming out of Afghanistan, and it really did a lot to help bolster the supply of gem Pollucites in the world. This gem is a remarkable, very slightly included, colorless stone with a Pear cut. This material is prized for its rarity, and all great rare stone collections need to have a good Pollucite in them.
