Set of Four Butterfly Brooches

Three are gold hardware, one silver. The silver one is fully silver, no colour accents. Extremely minimal surface scratches. Large gold butterfly has varied shades of orange in sparkly and matte stones. Very slight tarnishing is present. The two small gold ones are matching and red/orange. Mild tarnishing. All have the twist opening with pole for the backing. I believe they are vintage as they were from an estate sale.
