CAD designed jewelry: Hows and Why

by
Crafting jewelry is a highly complex and demanding task. For centuries, it has required painstaking work in making designs, models, molds, and casting metals. However, in recent years, new technology has allowed jewelers to design jewelry - from start to finish - with digital tools. CAD/CAM technology is a leap into the future of jewelry creation, allowing a piece to go from conception to creation quickly and with great accuracy.

CAD, or 'computer aided design', uses points connected by mathematically calculated lines to create a two dimensional or three dimensional model. This model can be manipulated, adjusted, and, in the case of 3d CAD, viewed digitally as a finished product. Where traditional techniques require hours of painstaking work that can be ruined by a single slip of a tool, CAD techniques allow fast, forgiving design of jewelry.

Once the design is finished, it can be shown to the purchaser for their approval. This is a wonderful advantage, because the customer- or the wearer - can be absolutely sure that the design they've chosen is what they really want. This, coupled with the ease with which the design can be modified, helps ensure that the jewelry is perfect before it is even made.

Then, the design is used with a CAM machine, or 'computer aided manufacture'. In most cases, this is either a computer controlled milling machine or a 3d printer. The machine can either make a model which will be used in casting the finished jewelry, or it will work the metal to make the actual jewelry. Once the machine is done, if a model was made, it will be used to make a mold to cast the finished piece. After it has been cast - or removed from the machine, if the metal was directly machined- the craftsman will finish the jewelry. He removes imperfections, polishes it, and attaches any precious stones that the customer has chosen.

CAD has many benefits, including the ability to reverse mistakes without wasting valuable time. A mistake on a hand-made model can often mean that the work has to be completely redone. With CAD, fixing that mistake is as simple as pressing a button. When this is coupled with the ability to show customers their design, in perfect detail, before any metal is worked, jewelers have a tool that allows them to meet every expectation quickly and without disappointment.

When you come to John S Cryan Jewelers for a piece of custom jewelry, you want it to be perfect. It should be everything you wanted, or it should be even better. We at John S Cryan Jewelers strive to exceed those expectations.
