Fold form trapped pearl pendant

Happy Wednesday!  This is a trapped pearl copper pendant made with the fold forming technique.   It's about 1.5" long and 7/8" wide.  The top forms a tube for the sterling silver chain. 

It's the first trapped stone design I've done.  I can look at it and see some improvement opportunities process-wise.  But, I'd love to have some feedback on this design -- what would you change?  And what is your opinion of pearls with copper?  Do you like the contrast or do you think copper needs a more rich or rustic looking colored stone?

I am going to try it again and would love to incorporate some of your suggestions if I can.

I try to post on my blog every Wednesday, so please stop by again.  My posts are mostly focused on the fold forming technique right now.  If the technique interests you as a metalsmith, please join our new community at http://www.facebook.com/foldforming .
