Addition # 9 - This is nice in any material and has a lot of sparkle. Cut this in about any size and you will be amazed at how much life the design has. I tend to like light to medium saturated colors for this design. It does work well in Garnet. Cut in refractive indexes 1.54 to 2.14 with no changes.
