Blue Topaz 2 strand Bead Necklace This gem necklace does well with a medium size pendant. The lovely pale blue topaz is micro pave faceted in a 2 strand necklace. Tempi uses a fine steel twist "Beadalon" wire to string all our beads, so a pendant weight can hang easily supported. Ends are crimped and covered and all our findings are sterling or GF over sterling. Choose a 16 or 18-inch length.
