VERY GOOD. This Art Deco 18ct Gold square Onyx ring is just beautiful. The gemstones are all securely set in place, and they have remained beautiful after these years. The ring band is a luscious 18ct Gold and there is only one minor resize mark to the back of the band. There is one small little nibble to one corner of the Onyx, but overall we find this beauty difficult to fault, she's going to be a splendid addition to your collection!
