This case study explores the creation of a custom diamond and sapphire bubble ring, designed and perfected using Computer-Aided Design (CAD) technology. Inspired by the playful elegance of clustered gemstones, the design required precise digital modelling to achieve a balanced arrangement of diamonds and sapphires in varying sizes. By combining creative artistry with engineering accuracy, the process transformed a modern, whimsical concept into a wearable statement piece that radiates both colour and sparkle.
