Addition # 4 - Almost no light is lost thru the pavilion except for the outside points on this design. It is not super bright, but with a 2.0 L/W and also a marquise, it is a lot better than most. It cuts bright and is very good for a lot of the long thin material(shaped crystals) that are available lately, 1-12cts. This also works in Garnet, Sapphire and Topaz.
