The pair has a silver tone round setting of ½" diameter. They could be worn by both females and males on any French cuff shirt. A great pair that is very versatile is in great condition with no makers mark. It depends on the way the light reflects off of the surface but I would say they are black but move them a different way and they also look grey and or blue.
