This client approached me to convert his family crest into a 3 heavy gold rings. Weighing over one ounce per ring (35gms) in 18ct yellow gold these rings certainly met his guidelines ! The process involved scanning the images of his family crest and importing it into rhinoceros (cad design software), then a long process of turning a two dimensional image into a three dimensional design. The results were worth the effort with the client very happy with the final results
