Sterling Silver Chocker - Vintage. This was used by me for wearing sterling silver slide pendants. I’ve owned it for years and originally purchased it at an antique store. Stamped Sterling plus one other mark I’m not familiar with (see photos). Stored in plastic bag so tarnish is present but I will not polish prior to shipment. Sold as is. Reach out if you have questions. Weight 29 grams on my kitchen scale
