Nice old 10K American Oil cuff link. It has a small red set, possibly a ruby. The back has what might be cTo along with the 10K. I don't know if I have the letters right or not. Please check out all of the photos for condition, possible gold content and to try and make out the letters for yourself. The color of the cuff link is a silver color, possibly white gold. Again, I do not know. I checked the internet for other pieces like this one. I did not find any. The stud is bent somewhat. This piece is being sold as is. I Will ship to U.S. address only.
