VERY GOOD. This antique 18ct Gold Diamond trilogy bypass ring is in very good condition. Each rose-cut beauty is securely nestled in its settings, each keeping their faceted form beautifully over the years! The 18ct Gold and Platinum are also in glorious condition, with only the odd very tiny sign of wear noticeable. The shank is slightly misshapen, most likely from a previous resizing, but this is only subtle. All in all, she is a divine antique bypass ring with a timeless beauty!
