Nan's scaled down super chic HeartLock invokes two compelling symbols of love; a padlock and key, whimsically shaped as a pavé heart that fits snugly into the lock like a puzzle piece. The key stays secure with hidden magnets and can be gently released by pushing from the back. This smaller version is a combination of 14k yellow gold and white rhodium over sterling. The center stone is available in a 1 carat pink sapphire heart or NEW Columbian Emerald heart bezeled in diamonds. Necklace measures 17 inches.
