Israeli designer Simon Sebbag. 925 Sterling Silver. Clip on drop hoop earring. Aprox 2.75" long. Lightweight and comfortable. Process from 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."
