These beads are my new favorite. I'm making hundreds of them and when they're put together like this, I love them even more. This necklace has about 3" worth of beads strung on a sterling silver chain. The colors are electric! Purple and Aqua accented by the subtle beauty of opaline...makes me kind of crazy. The glass is borosilicate, which is stronger and more durable. The length is about 18". I love this necklace and hope you will too. Thanks for looking!!
