Gemstone Necklaces, an Idea in the Making

I've been thinking of new necklace ideas that feature stones and how to use them so they are not only beautiful but secure. I woke up with an idea to use agate since it already has a hole in the center. I don't want to braid these necklaces like I do with the feathers, but have a very simplified design. I'm thinking I need to secure them around so the necklace isn't all over the place. It's a work in progress, but you can see it in its simplest form here.
