Vintage 10k Gold Class Ring 1958

Solid 10k UC class ring. (University of California?? Not sure). This has a nice weight to it and a beautiful mother of pearl stone shines pink in a certain light. Class of 1958. Shows size 9 on the sizing sheet, but because of the larger front, it fits my size 8 finger. So I would say it might be closer to a 8 & 1/2 fit size.
