Platinum ring with a .80ct diamond, ring is dated 1933

Vintage platinum ring with a .80ct old cut diamond. The diamond is VS2 in clarity, F-G in color. The ring measures 5/16" wide and is a size 7 1/4. The ring is dated on the inside, 1933. I have not have the ring polished to a bright mirror finish, it does show some wear but I liked the matte finish it has gotten over time.
