This is a single crystal with good luster and a deep royal blue color. At the crystal edges, neon blue highlights can be seen even in normal lighting. When strongly backlit, this is shown to be a very RARE GEM CRYSTAL, transparent through and through! EXTREMELY uncommon, especially in this size. Ex. Charlie Key.
