This store is at a very convenient location (union square) if you are looking for antique style ring. They have a pretty good selection for rings and bands. I went there twice, and both time were well recieved. They sales persons were friendly and very knowledgable. Although they are not the cheapest shop in town. This store makes a very good scouing spot.
This is simply *the* place to go if you're shopping for an antique engagement ring. They have the biggest selection in the Bay Area, and the selection is truly staggering.All the $5000 and up rings are in the window, but there are beautiful under $5000 rings inside for the rest of us. They seem to specialize in Art Deco.
They have other interesting estate jewelry items as well such as vintage cuff links (which would make a good wedding gift for your partner).
