Trouble finishing things and Firemountaingems competition

The banner on top of the page is actually a photoshopped unfinished bib necklace. And now that Firemountaingems.com has a competition going I would like to enter, I really have to finish this piece and take good photos. The best prize is a $1000 certificate to the website/store, even a pity price would be great since there are so many great jewelry supplies. But somehow I am stumped as to how to complete this piece. Of course I have tons of other things but I think this one is the most eye catching, and has a change, as they say on Project Runway, Make it happen!
