The Lyric sterling silver jewelry collection by Frederick Goldman is full of all kinds of intricate details that suggest some carved the designs into the metal. Of course, that's not how they were made, but it's more than just filigree here. With the addition of oxidizing the metal, it makes the reliefs pop out of the jewelry piece. For example, pictures left is a ring with pink and 18kt gold accent.
This is the sort of sterling silver jewelry that you don't want to do too much cleaning to because you can end up taking off the dark oxidized areas and totally changing the look of the piece. They site suggests just using a polishing cloth to rub it down now and then.
