Are you looking for a gift for your favorite scientist, or are you looking for an accessory to wear to your next geek party? Then maybe this DNA necklace could be the answer! and for those who do not care about science as much as I do, this could be a simple abstract neck jewelry piece :) The pendant in this necklace is created out of glass (by me) using fused glass technique. The different shades of glass are cut, shaped, layered and fused multiple times in a kiln. Dimensions: ~ 3 cm x 2 cm (1.1" x 0.71") The bail is sterling silver. The included sterling silver chain is a sturdy, elegant, and comfortable chain. It is available in 45 cm (18").
