Free Earrings Giveaway - Help Me Finish a Necklace

I want to make a pendant on black rattail satin cord with these beads. They are gunmetal beads in 3 sizes, largest is about 15mm and ~10mm cobalt blue glass barrel beads. I will probably put decorative knots on the cord but no other embellishments. I need a focal piece/pendant for it and I'm so brain tired from the weekend, I can't even contemplate searching right now without wanting to take a nap.

So, if you'd please leave some links to a focal or pendant - the specific item, please - that I can go see (and maybe buy) from Etsy shops, Artfire shops, other online shops, or bead suppliers of focals you think would look good with these.

If I buy the focal you suggest, I'd be happy to make you a pair of earrings as a thank you gift...either out of these materials or we can work out what you'd like via email. If I don't buy a focal suggested, I'll do a random drawing from commenters. If the winner doesn't want earrings, we can work something else out, but I really do want to give away a prize!

And yes, this may get me some traffic and comments, but it really isn't my intention. I'm truly so brain and body tired from last weekend that I can't seem to figure this out on my own right now and really would love your ideas!
