This is Double Helix odd lot K-108:
I can't get enough of these silvered metallic glasses. Years ago when I worked with tiny seed beads, all of the Iris colors like Iris Blue, Brown, Green, Purple and the metallics like Gunmetal, Silver and Gold were my favorites. My tastes haven't changed, I still love this look. I even changed my avatar today to a picture of some of my favorite beads from this past year - disc beads made from Nyx glass.
