Natrolite is one of the very few facetable Zeolites in the world. This stone is from the recent collecting at Bound Brook, New Jersey. This gem is an exceptionally rare, very very slightly included hard to find, "collector's" stone. The fact that the stone is so clean makes it pretty special. The cut on this stone is an Emerald cut. If you're a serious gem collector, you need one of these in your collection, especially if you like to collect gems from North America, or simply from the United States.
