Several years ago I came across an Australian design called "Robin", but have since lost the original reference. It's a cut corner square design with a deceptively simple pavilion and apex facets. If anyone knows the original source, I would be most grateful to have more information. I've included a GemCad image which might be close to the original concept, and shows one of the apex facets reflecting white light.
