Our Star of David Necklace comes to you in sterling silver and blue CZ on a chain measuring approximately 16 inches in length. If you prefer a longer chain, you can select 18 or 20 inches for a small additional fee. The featured pendant measures just over 20mm tall (which is 0.8 inches in girlfriend lingo) and just over 17mm wide (which is 0.7 inches in girlfriend lingo). Floating in front of the star is an oval framed blue CZ. It's a beautiful symbol and were happy to share it with you. Let it shine!
