Nephrite jade color cabochon gold tone cocktail ring

This is a superb Nephrite jade color cabochon gold tone cocktail ring. It could be a natural stone but I’ve not seen any peppery inclusions inside it, so I’m selling it as nephrite jade color stone. It is a 6.25 and appears to be plated with high carat gold but it’s not stamped. There are two tiny scratches on the ring shank only visible on close inspection with 10x magnification (please see the close up pictures), otherwise In great vintage condition.
