Every ring has a story.... I took this to our local jewelry and here's what he said: 14kt plated Probably used as a decoy ring to dissuade thieves, potentially during the late 1800s (a common practice for that time period) Tarnish most likely came from sea or salt water Stones are CZ or glass Other materials unknown (probably brass) Gypsy dome shape is rare 14kt gold plated nugget ring Size 10 Vintage Antique Has scratches, wear, patina tarnished as expected for age A piece of history!
