Fine Jewelry Casting: A Peek Behind the Curtain
We thought it might be interesting to pull back the curtain a bit and show you how small pieces of precious metal become a piece of fine jewelry.
Sorella uses the lost wax casting process to create our jewelry, a method of casting metal which has been around for thousands of years and which creates the finest jewelry.
- The piece begins with the creation of a CAD (computer-aided design) drawing which is then used to create a 3D wax model of the piece.
- The model is then covered with investment (a type of plaster) and left to harden.
- The plaster with the wax in it is then placed in a very hot kiln which melts the wax, leaving an exact negative copy of the wax model … hence “lost wax casting”
- This hole is filled with melted precious metal (which starts out as “grain” as shown in the photo of silver) and allowed to cool. Once cooled the investment is broken open revealing the raw casting.
- A jeweler then finishes the piece, which includes polishing, setting gems and engraving.
Below you’ll find in-process photos for two different custom pieces documenting four of the steps in the process:
- CAD drawing
- Wax model
- Raw casting
- Finished piece
