Granat Brothers began when brothers Joseph and Leo Granat opened their first store in Stockton, California in 1905. Joseph and Leo decided in 1927 to build a retail shop with attached manufacturing workshop at Mission and 20th Streets in Stockton. The flagship store was located at Grant and Geary in San Francisco and opened its doors in 1922. The company expanded quickly and by 1961 there were a total of nine locations growing onward to twenty locations. Then in August of 1961 Zales purchased the retail locations and the manufacturing side was sold to someone else. Before the company sold they established a nationwide distribution of their manufactured designs to over 1000 retailers. Granat Bros. held a trademark on the name Wed-Lok and attempted, unsuccessfully, to patent the process of these interlocking wedding sets in 1950. That being said they did patent many other jewelry related items that were consistently produced well into the 1980's.
