The pendant features a 7.0mm black Tahitian pearl & 18KGP white gold setting. The pearl is green peacock in color, thick nacre and excellent luster. All of my Tahitian pearls come from the remote South Sea Islands of Tahiti, they are hand picked. The chain is "925" sterling silver layered with 18K white gold (16" in length). This necklace could be a perfect gift for the one you love or a nice treat for yourself.
