I came across a 73 carat piece of very nicely colored kunzite from Afghanistan, and this design almost exactly fits the shape of the rough. Mind you, it was a bitch and a half to figure out how to make this design look good and be reproducible... Works in materials from feldspar to zircon (RI = 1.52 - 1.93) with no changes. Suggested length = 10-20 mm
