1500- Beautiful Ring but has No Markings on inner band I am not a gemologist or a jeweler so I could be wrong on identifying certain stones or pieces of jewelry. The item is pre-owned, there is wear that you would expect over time. Surface scratches, scuffs, or tarnishing. Please view all pictures and zoom in for further details, size. I do not disturb my vintage jewelry in order to keep its original patina leaving it to your discretion. Depending on your own taste, you can either polish it or keep it in the same condition.
