Unlike most Internet jewelers, at Diamond Design Co. each piece of jewelry is carefully designed and crafted by our in-house jewelers.
Need it wider, smaller, more stones, less stones, a different metal or precious stone, NOT A PROBLEM. Our jewelry is made-to-order-, "made by us for you".
We are located in the heart of San Francisco, near Union Square, inside the Historic Phelan Building. We love this location because it is not only in beautiful downtown San Francisco, but also we're close to many restaurants, shopping, and easy access to transportation. BART (Powell St. Station), Muni, Market Street Trolley and Cable Cars are just steps away. Please come visit us.
