Matthews Jewelry, carrying pieces from designer Michael B. exclusively, is located on Ventura Boulevard in a large building with several of their pieces delicately laid out in window displays. A doorbell lets guests into the main showroom, where a wealth of diamond and pearl pieces are displayed. The inventory isn't huge, but the craftsmanship of each piece is highly revered throughout the city. The staff are knowledgeable, friendly and more than happy to let customers try pieces on.
