Judging from the pictures the 10 k rings looks 100% like gold, the 14 is harder to tell for me. The picture of the 14 gold doesn't have the contrast for me to detect the crystalline structure on the surface to make a declaration. I do see that structure on the in the 10 k gold, gold plate shines and sparkles without any reflective cuts, and most EGP has a coating of lacquer and highly polished and buffed, gold isn't like that.
So need a better pic IMO on the 14 item.
