Jewelry repair and restoration with CAD gives jewelers new options when a piece is too damaged for traditional bench repair alone. Worn-down shanks, broken prongs, missing components, and damaged settings can be digitally rebuilt and then produced through printing and casting. Our jewelry services team in Los Angeles supports jewelers and clients with CAD-based restoration work.
When CAD Makes Sense for Repairs
Many repairs, like retipping a single prong or soldering a broken chain, are best handled at the bench by a skilled jeweler. CAD becomes valuable when:
- A large section of a ring or setting is missing or severely worn.
- A matching component, such as a missing earring or a broken pendant part, needs to be recreated.
- A design element must be rebuilt symmetrically, such as a damaged gallery or filigree.
- The client wants to keep the original look but strengthen weak areas.
Common CAD-Based Restoration Projects
Worn ring shanks
Rings worn daily for decades can thin dramatically at the bottom of the band. A new shank section can be designed to match the original profile, then cast and joined by the jeweler.
Rebuilding settings and heads
When prongs are worn or a head is damaged, a new head can be modeled to fit the stone precisely, matching the original style or improving its durability.
Replacing missing pieces
A lost earring, a missing charm, or a broken element of a brooch can be recreated by scanning or measuring the surviving piece and producing a match.
Restoring detailed patterns
Engraving, milgrain, filigree, and pierced galleries can be rebuilt digitally where damage makes hand reconstruction difficult.
How the Process Works
- Assessment. The jeweler evaluates what can be repaired at the bench and what needs new parts.
- Capture. The piece is measured or 3D scanned. Intact areas serve as reference for damaged ones, often by mirroring.
- CAD reconstruction. Our designers rebuild missing or worn sections to match the original.
- Printing and casting. New components are printed in castable resin or wax and cast in matching metal.
- Bench work. The jeweler joins, sets, and finishes the piece so the repair blends in.
Matching Metal and Color
To make a repair invisible, the new part should match the original metal’s karat and color. Older gold alloys can vary in tone, so jewelers often consider plating or careful alloy selection to blend the repair.
Sentimental Pieces Deserve Care
Many repair requests involve family heirlooms. Scanning the piece before work begins creates a digital record, which can be reassuring for the client and useful if the piece ever needs repair again or if a replica is desired.
Repair or Recreate?
Sometimes a piece is too damaged to restore economically. In those cases, recreating it entirely in CAD, using the original stones and possibly some of the original metal through refining, may be the better option. We help jewelers and clients weigh these choices.
