Jewellery CAD Design (Computer-Aided Design) is the process of creating precise, digital 3D models of jewellery pieces before they’re manufactured. Instead of relying only on manual sketches or wax carving, CAD lets designers visualise every curve, prong, and stone seat on screen with microscopic accuracy. Modern jewellers use CAD because it eliminates guesswork and ensures a flawless fit for stones, symmetry between earrings or rings, and predictable metal weight. It also speeds up client approvals—customers can see realistic renders before any casting begins. CAD files such as STL, 3DM, and OBJ can be sent directly to a 3D printer or casting house anywhere in the world. In short, CAD design saves time, reduces material waste, and increases production consistency—making it an essential tool for every professional jeweller today.
