Sheri has been used sterling silver since the very beginning of her jewelery career. Because she uses only the finest grades (.999) her pieces should not have any tarnish unlike jewelery set with lower quality silver. The pieces are all hand crafted and each piece is usually bezel set. Sheri also uses a process where the sterling might have an oxidation in the background and polished on the top giving the pieces a 3 dimensional look. Her pieces are all stamped Sterling and all have her signature.
