VERY GOOD TO EXCELLENT. This Art Deco 18ct Gold Onyx Diamond ring is in very good to excellent condition. The Onyx is smooth and beautifully cut, and the Diamonds are exceptional! One of the corner Diamonds is possibly a replacement or has been re-cut, and you can tell this where the setting has an additional section, but this is only visible up close and personal- if this is the case or whether this was always the design we are uncertain. The central Diamond little darker at J'K, I clarity, whereas the corner Diamond are G-H colour and Vs-s clarity. The ring band is hallmarked '18CT', and wears comfortably on the finger.
