I am often asked about the process for creating a custom designed piece of jewelry with the use of CAD (Computer-aided design).
CAD has been a great innovation for helping people see what they are going to get before they actually commission a piece of custom-made jewelry. The cost is minimal, and many revisions can be made until it is clear that the jeweler understand what the customer wants.
This can be a short and simple process or a long and convoluted process. A lot will depend on how well you know what you want.
