The item is a 10k white gold amethyst pendant with a 18 inch or 45.72 centimeter long rope chain. The chain has a spring ring catch on the end. The amethyst measures 5 millimeters round and is held in with four prongs. The carat weight of the stone is .42. The metal around the stone is designed to shine a lot and look like a diamond halo around the amethyst. The pendant is 12 millimeters long and 8 millimeters wide. I will provide a nice pendant box with the item.
