These cuff links are made of sterling silver with what looks like a turquoise glass stone. It is not a solid turquoise color but has some beige striations throughout. The stone itself measures 11/16" X 9/16". The entire face measures 7/8" in diameter. I have cleaned them up a little since they were black but they could use a little bit more. They are stamped sterling with some numbers on the back of the toggle. It was difficult to get a photo because of the position. The weight is 16.20 grams. Very nice condition.
