CAD when the setting does not exist
CAD is the right tool when a reference photo, a center stone, a side profile, or a wedding band plan needs a made-to-fit setting. You review and approve the proportions before production. Nothing is built until the design is exactly right.

What gets decided
Plenty of beautiful custom rings never need CAD, and skipping it when you don’t need it is one of the easiest ways to save money. When you do need it, you approve the design before a single thing is made.
01
CAD defines setting height, basket shape, prong placement, side-stone angles, bezel thickness, band width, and wedding band clearance, to the tenth of a millimeter, around your exact stone.
It earns its keep on three-stone rings, step-cut bezels, unusual center shapes, low profiles, and designs that start from a photo of a ring that doesn’t exist yet.
02
CAD should never turn a clean design into something overbuilt. The strongest custom rings use the tool to clarify the idea, not to add complexity for its own sake. If your ring doesn’t need it, I’ll say so. That answer costs you nothing.
03
Before anything is made you’ll have signed off on the stone, the proportions, the setting direction, and the timeline. The design you approve is the ring that gets built.

How inspiration photos become custom engagement ring plans, and what details need to be translated before production.

When to modify an existing setting and when a full CAD custom engagement ring is the better route.
Read guide“Andrew reset my grandmother’s diamond into something Lauren actually wears every day. He handled it like it was his own family’s stone, and he returned the old setting in a little pouch, which meant the world to my mom.”
It can translate the design direction and proportions, then adapt them to your exact diamond and hand. What it shouldn’t do is clone someone else’s ring line for line. The result is built for you.
It adds review time, and it prevents the far more expensive kind of delay: a finished ring that isn’t right. Most CAD projects still land inside the 14–30 day window; the complicated ones get an honest timeline up front.
