The item is a sterling silver green and blue onyx bar necklace. There are three cubic zirconia set in between the green and blue onyx cylettes. The pendant measures 3/4 x 1/4 inches and weighs 7.4 grams. The chain is a adjustable silver wheat chain with a lobster claw catch. The chain is 20 inches long at its maximum length. This item is made by jewelry designer John Kennedy. I will provide a pendant box.
