An artistic flair is added to every piece of Koop Custom Jewelry designed by Koop Diamond Cutters master jewelers and technicians who combine their natural talent with generations of experience, skill and knowledge. The custom process is an evolution that starts with a creative conceptual meeting and leads to the jewelry art design process involving sketches and computer-aided technologies of the design, analysis and manufacture of the jewelry. This process is referred to as Koop Diamond Cutters ICDS (Interactive Custom Design System).


Master jewelers use careful consideration and skill in every step taken towards the finished product, guaranteeing clients complete satisfaction with the detail, craftsmanship and beauty of their one-of-a-kind custom jewelry piece.
