I never thought you could actually make your own custom diamond engagement rings but I guess it is possible by using wax and then making a mold out of that. Of course, I don’t think that’s going to be easy but if you have the right tools like 3D software and a laser CNC machine, this could be some easy job for you.

A client wanted a traditional design for his engagement ring.
This instructable shows you how his ring was created using the lost wax casting system.
To begin with I cut a section of jewellers wax, ( a special wax that has great properties for cutting, sawing and carving) into the basic ring shape. I created a hole the same size required for the finished ring.
