Rainbow Wrap -- Pendant??

I wore my Rainbow Ring to work today. It is a little oversized for me, but I thought i would try it. Well I got to thinking - why couldn't I fashion a Pendant to match? the pendant could be chunky, and it would be a good thing (as opposed to carrying a boulder strapped to your finger!) I might just try it with the next batch of stones I get. If anyone has any ideas, let me know please?
