This 11.6 ct (appx 2" x 3/4") natural wild found abalone pearl was part of a phenomenal vintage collection. It has fantastic color on both sides. This pearl is between 2.5-4.8mm thick! It will require a skilled jeweler to set this VERY rare pearl. Once the pearl is set it will be a true work of jewelry art! ID#KDP2/7/25/11.5ctAB
