This is one hell of a unique design. From the zeppelin outline in the crown, to its absurdly high H/W ratio that gives the finished stone the feel of a zeppelin in the hand, it's definitely unique. Also a bitch to cut, hence doom to the unfortunate cutter. Works in materials from quartz to CZ (RI = 1.54 - 2.16), but best in tourmaline crystals. Suggested length = 12-20 mm
