Shadow band customs are a work in progress for me. I don’t have access to or know of any affordable technologies to scan rings to bring into CAD so I take pictures of the rings and model a band to the pictures to the best of my ability. Sometimes I’ll even remake the ring in CAD if the photos aren’t enough. Then I will grow a wax to test the fit before I show the client. I have gotten better with this method but I believe there is still room for improvement. Let me know your thoughts. Thank you!
