This 2" pendant is made from blue goldstone beads, a single Preciosa fire-polished bead (clear, with aurora borealis finish!), and tarnish-resistant silver-colored wire. Blue goldstone is a kind of manmade gemstone that sparkles in shifting light, looking almost like a miniature bit of starry night sky. Comes with an 18" silver-tone chain with 1" extender section. Variants available upon request!
