Many tourmaline crystals have broader bases than the areas toward their terminus and when you trying to get the most of a spectacular sea foam tourmaline crystal, you cut for the largest quality stone you can get. This is why the pair of Barion cuts I made from a single large crystal from Afghanistan are not identical. Still if seen apart, they appear to be identical expressions of pure tourmaline delight. Nothing is wrong with this high quality gemstone. This bigger brother weighs 13.39 sparkling carats.
