A family business. Since 1979.
Todd and Howard Katz began as gold buyers in the greater Philadelphia area. By the 1980s, the business grew into diamond wholesale, building relationships from New York to Antwerp. Today, Todd, Howard, and Zack bring that experience to a full range of jewelry needs—buying, selling, creating, repairing, and repurposing.
Recent projects. Fresh inspiration.
Stay in the Katz circle.
