The item is a sterling silver diamond lariat/y/bar necklace. The bar portion measures 22 millimeters long and 3 millimeters wide. The chain is 20 inches or 50.8 centimeters long when fully extended. The extension chain is 2 inches long. There is a lobster claw catch on the chain. There is a 0.01 carat diamond set into the pendant on the bottom. This diamond has a "G" color and an "SI2" clarity grading. This item weighs 5.4 grams and I will provide a nice pendant box.
