The item is a 18 inch or 45.72 centimeter long 14k white gold rope chain with a spring ring catch and quarter carat round diamond. The diamond measures approximately 4 millimeters round and weighs approximately .25 carats. There is a small nick on the girdle of the stone that is visible under magnification. The stone is a "I" color and a I2" clarity grading. I will provide a pendant box with the item.
