Sterling Silver Marcasite Bar Pin Brooch Tie Tack 1920s Edwardian + Gift Box

This screams roaring twenties to me. I am not sure how old this is but it looks like an Edwardian era vintage piece in marcasite and sterling silver. This is a bar brooch or tie pin (both sexes wore them.) On the pin it is marked 955 for sterling. Delicate and intricate design with marcasite insets. All the stones are intact. It has an early style safety catch so I would date it about 1920. Please see photos, it does look better and more sparkly in person than in the photos. I have given it a light polish but I know some prefer the patina on so if you would like it shiny it could use another polish. Comes in a new jewelry box, great for storage or for gifting. Box size varies. Size: 1 5/8" l x .5"w (4 cm x 1.5 cm) Condition: Great condition for age, no missing marcasite stones. Have you found your thing of beauty?
