Nice sizes gold circles, 2 of gold and one black. I am not sure what the black ring is made from. Probably onyx since Nabco seems to like using onyx. One black ring is unglued off the gold rings and needs to be reglued. I tried but it didn?t stay so I feel a jeweler needs to do this. This still could be scrap. The price of gold is just going up and up! 14k Nabco is marked on the posts but I couldn?t get a picture.
