This 1.66 carat has a very nice cut, Barion cushion, that mixes the two colors, golden and yellow, well. It has a simple two step crown.
This 1.66 carat Barion Cushion is about as small as I make this style of cut. (pavilion a Graham design) It was done to try and mix a golden c axis color with a purer yellow a/b axis color and get a good yield from a thicker piece of rough. The mixing work as expected and the general impression of the gemstone is golden, but you can still see the a/b color in a band across the middle of the narrow dimension of the stone as expected. I put a simple step cut on the crown, since it was easier to control depth and I am not really in favor of putting a lot of small facet in complex designs on smaller gemstones.
