The item is a sterling silver triangle geometric style diamond necklace. The chain is a silver box link chain with a jump ring soldered at the 16 inch mark. If you look up the lobster claw catch here you can wear this at 16 inches. Fully extended is 18 inches. The diamond has a "G" color grading and an "SI2" clarity grading. The diamond weighs 0.01 carats. The diamond is set into the point of the top triangle. The item weighs 3.9 grams and I will provide a nice pendant box.
