Gorgeous Vintage Large Moss Agate Figural Crab Brooch

Centered & perfectly set in silver is a beautiful oval Moss Agate stone. The metal design looks to be purposefully rough depicting a real figural crab. It was absolutely filthy when I received it and I used a sterling polishing cloth and it cleaned up beautifully. Possibly Sterling, Non reactive to magnet. It’s a substantial piece with some weight to it & the moss agate stone is beautiful. Hallmarks: None Measurements: 2 1/2” length x 1.75” wide Condition: Beautiful vintage condition with no noted flaws
