Dark black with smooth clean surfaces. What more could one ask for in their hunt for an unusual, natural color black tahitian south sea cultured pearl necklace. This necklace's raririty lies within its pitch black tone—a nice compliment to darker skin tones. Drop shaped pearls make a big impact compared to their round counterparts due to there length. An 8 millimeter by 11mm pearl refers to the size range of each pearl on the necklace starting with the end pearls and graduating to the largest center. Each pearl is measured at its narrowest width.
