The item is a sterling silver cross, lab created opal and heart pendant with a 18 inch long silver rope chain. The chain has a lobster claw catch. The cross measures 11 x 9 millimeters. The heart is plain on both sides and it can be engraved. The lab created green opal is held in with four prongs. The stone is held in with cement on the back side as well as the prongs. This item weighs 2.5 grams and I will provide a pendant box.
