I desinging my own wedding cake and have someone else doing it and i know that i want to use diamond and dust. Does anyone have any suggestions on what kind of design to use to accent the diamonds? and i have never used dust. I just want a little shimmer is that what it does?> 
Personally I love the jewelry sprays out of the top of the cake. I also like the look of the diamond impression and placing the jewels where the diamond points meet randomly around the cake. But here are some topics and links that might give you some ideas=) Congrats on your wedding!! HTH some, Jen
