Here are 2 variations on a theme. The one with the green stone beads (African jade) was made a couple of months ago, and I was pretty happy with it. I like that it is regular, and yet the sawtooth edge breaks up the symmetry a bit. But recently I started wondering how I could take the idea and make it a bit more dramatic. The answer turned out to be size. By increasing the size of each unit from around 1.5 inches to over 2.5 inches, I made a necklace that, to me at least, has more impact.
