Hi there,
I am a new member so please excuse any blunders.
I have to do a cake which has sparkly edible diamonds or diamantes on. I have bought a few to try but they seem very chunky (about 1cm) and dull although from a sugarcraft shop.
Could anyone recommend any suppliers please?
I have seen some gelatine ones on ebay - has anyone tried them?
I would be grateful for any help.

I haven't seen any that were impressive once in person

If you want real sparkle, you're going to need to go with real, inedible rhinestones.
