Hi!
One of my projects is creating floating candles that are going to go on the cake, gift & welcome tables. I have the materials, I just need to know if I should go with Clear, blue, or blue&clear rocks. I have little heart candles that will be floating. I can't decide and I tried playing around with everything just now.

with blue rocks, no candle

blue & clear rocks with candle

Note I didn't get pictures of the clear rocks by themselves. I didn't like how it looked.
Thanks
