This is just a stunning gem portion of a Pollucite crystal from the Walden Gem Quarry (pegmatite) in Connecticut. This glassy, lustrous, slightly elongate gem growth (partially crystallized but worn or cleaved) measures 2.1 x 1.3 x 0.9 cm and has a mass of 3.4 grams. Pollucite is a rare cesium-sodium-aluminum silicate hydrate that forms in highly fractionated granite pegmatites, and found even more rarely in gem crystals or fragments like this. The Walden quarry was opened for specimen mining in 1962 and is famous for large masses of gemmy Pollucite from which many gemstones have been cut from the material - although rare, today. A gorgeous thumbnail specimen of this material. This beauty comes mounted in a contemporary thumbnail display box for great presentation. Paterson Museum collection to James Zigras by exchange, and later in the American thumbnail gem species collection of thumbnail collector and speaker, Jim Houran.
