I have 3 sets of this new design in my Etsy shop - Rock Pools. They all start out with a transparent glass which is then covered in trails of a double Helix silver glass, reduced and encased. Some then have a couple of pieces of .999 fine silver added, melted into dots in some cases (I love that look), trails of a clear and white twistie added and encased again. I am really pleased with the watery summer look of these beads.
The beads in the last set are all slightly different, but all with the same look.
Thanks for looking!
