CAD (Computer-Aided Design) is an excellent tool for designing custom made jewellery. Whether you’re creating a custom piece of jewelry or just want to analyze and visualize the diamond’s facets, CAD can help. For diamond design, you’d typically use specialized software that allows you to create a 3D model of the diamond. You can manipulate various parameters such as cut, carat, color, and clarity to see how they affect the overall appearance of the diamond. This level of detail is crucial in the jewelry industry where precision matters.
