This version of the Comet Necklace is set with fourteen 2 mm synthetic gemstones and hangs from a 16 inch sterling snake chain. (Also available in 18”, 20” and 24” – to order a longer chain, find the item “Comet Necklace – Chains”.) It is shown in Tourmaline Pink & Padparadscha Orange and several combinations are listed. But special orders are welcome. If you want a different combination, or just a single color (all colors shown in the stone sample photo are available for this necklace), order the default and describe your preference on the checkout page.
