Among the beautiful tourmalines, and beryls for which Paprok is so well known, occasionally are found these killer gemmy petalite specimens: petalite is a fairly rare lithium, aluminum, silicate. This particular petalite is large, lustrous and transparent. It has been slightly etched as are most, but retains the overal lcrystal habit. It is very gemmy and transparent! Complete all around. Formerly in the collections of Richard Gaines and ex-Smithsonian curator John White.
