I don't know if you're still around, but those sound really beautiful. I'd love to see a picture.

My "formula" for pricing my work varies. That's a lot of help, huh?

I think it's important not to under price what you do - which is a common mistake. Add up the cost for every material you use, then add what you think is a fair price for your labor. Of course, you won't be making much for your time/labor at first...but when you make a name for yourself and have some experience in dealing with people actually paying you for your art, then you can tweak your prices. A lot of times, artists/crafters feel like the price they set is permanent. It isn't! You can always adjust your prices if you feel they are too high - or worse, too low. It's tough to strike a balance between being compensated fairly - and not pricing yourself out of the market.
Another suggestion I have is to go to some of the online art/craft shops - etsy.com, artfire.com, etc - and see if anyone is creating anything similar to what you're doing. If so, take a tip from their prices. If not, great - you have something totally unique. Try to find something kind of similar and go from there.
You'll know pretty quickly whether you've done a good job at pricing - just never forget that setting a price is not an end-all, be-all. The costs of your materials may change (ie - you're selling a lot and can begin to buy things in a large enough quantity to look into wholesale buying, etc), the economy may change, you may become the next Michele Beschen - which can all impact what you charge. Feel things out, try out a couple of prices, ask your friends/family/other crafters what they would pay (or charge) - and go from there. Don't get discouraged if you sit down to break all your own costs down and find out you're only making $2 per item. Most artists/crafters don't get into selling things because they want the money...which they do...but they get into it because they feel like they *have* to create, or (like me) you make so many things, you run out of space! lol
Good luck - I hope you've found a pricing system that has worked. Would you mind posting an update, if you're still here?
