Qing Dynasty Antique Chinese Silver and Enamel Handmade Repousse Adjustable RingEstate Find! A unique and beautiful piece of history. These rings are very hard to find with any enamel left.19th Century ChinaThere is a depression or what might look like a hole on the face of the ring, on the body of the fisherman. It is not clear to me whether this was intentional, a mistake during production, or possibly had a small gem at one time... or perhaps a hole for poison!To the naked eye..., there are not silver or jewelry stamps. Most likely 90 percent silver.Please email me with your questions.
