Stunning and unique vintage pin. 925 Sterling Silver from Israeli designer Simon Sebbag. 2 3/8" tall and 2" wide. Process as described on their website: "The jewelry is produced using a unique electroforming process. In electroforming, a wax mold is created and inserted into a computerized 925 sterling silver bath. The mold remains in the bath until several thick layers of silver adhere; the result is a light and comfortable piece of jewelry. Finally, the piece is hand-polished to achieve a brilliant shine."
