Superb modernist sterling and Amazonite brooch/pendant necklace. It has been professionally polished and is in excellent condition. Stone is fully intact with no damage and is shiny and bright. Any weird black lines or marks in the photos are just reflections or shadows. It's very shiny and hard to photograph.
