okay, this was a very hard cake for me to do . These are carved from 12" round cakes. This was for a 25th anniversary, I know it is the silver anniversary, but the bride and grooms bands are gold, so we went with that. they are covered in buttercream icing. The diamond is RCT or RKT covered in fondant. I think if I had to do this again, I would have a better support system, the top ring sagged a little in the middle. Thanks for looking.
