Posting this amazing ring for a friend. Did some research and this most likely is fossilized ivory (walrus tusk, teeth or even mammoth). Found in Alaska, Canada, Russia and Siberia. It's 1-3/8" and weighs 18 grams. Etched markings Kub...? or Ru3...? - can't read the rest of the designer's name. Also marked 3/17/86 Sterling Ivory.
Very nice quality. Not adjustable although looks like it is. Size 7.
