Hi everyone...can you give me a hand? Using this guide here  - http://www.diamondpartyconfetti.com/Sizing_Chart.html .... Im wanting to purchase the sugar diamonds but not sure what size I should get. these will go on sides of 3 tiers (6/10/14) square cake.  When I take the end of a bic pen, and indent into my buttercream...I like that size of the circle (make sense) which when measured..its around 1/2 CM.   Should I go with the smallest size they have listed, .6 or use the medium 1CM. 

Have you used these?  Just wondering how close to size these circles really are.  Any help would be great!!

Thanks

I'd want to use the 1cm on the 14 and the smaller ones on the other tiers. I'd even look to see on the middle tier  if I liked the bottom row of gems to the big ones then the rest the small ones just to see if the graduation made a difference.

I'd order both and see how it looks.

I'd probably want to punch them in farther on the top tier so they look smaller--maybe.
