I found this really cool eco bracelet designed by Kristin Coffing on Etsy. Real twigs in bud were cast in recycled sterling silver to create this unique cuff. The bracelet is fairly flexible, fitting very small wrists and large wrists alike. It measures 6" around, from end to end, not including the open space which is adjustable.
Wear it alone for a beautiful singular fashion statement or stack it on with your favorite bangles. The price is $130 and available on www.etsy.com/shop/kristincoffin.
