Hubei turquoise rose gold tone sterling silver size 7.25 ring

This is a one of a kind natural / genuine Hubei turquoise cabochon set in rose gold tone bezel and sterling silver mount. It is most probably rose gold but the stamp has been removed during sizing, so I’m selling it as rose gold tone. The silver tests positive for sterling silver with the acid test. A size 7.25 and in excellent vintage condition.
