I just finished posting a selection of my Albers pendants on etsy, grouping them according to color. I have two groups posted right now--a cool group, featuring blues and greens with a tad of black thrown in, and a warm group with reds, yellows, and oranges.
Each pendant has a silver-plated bail epoxied onto the back so you can put it on your favorite chain. I have a 14" chain and a 16" chain that I wear depending on my neckline.
The pendants are just $18 each. Check them out on our etsy shop! http://www.etsy.com/shop/OmegaArtDesign
