The electroforming process is when the resin is molded and is put into a tub of charged sterling silver. Over a 10-12 hour process, the sterling electrically forms (i.e. electroform) itself to the mold. Then the piece is removed and handcrafted to include more detail, oxidation is also done to create depth. ------------------------------------------ All our Sterling Silver is 100% Guaranteed crafted from .925 silver and is the standard for beautiful high-quality silver jewelry and cannot be replicated by lower priced silver plated jewelry.
