The iridescent and romantic finish of the opal makes it a popular gemstone among all jewelry collectors. The Sterling Silver Heart Created Opal Diamond Pendant Necklace brings the look of this beloved stone into a heartfelt setting that is affordable in price. A heart shaped created opal stone is outlined by a band of synthetic white diamonds. The pendant rests from an 18-inch rolo chain that is finished with a lobster-claw clasp. Remember, Opal is the birthstone for the month of October.
