The basic diamond cutting process includes these steps; planning, cleaving or sawing, bruting, polishing, and final inspection. [6] A simplified round brilliant cut process includes the following stages: Planning – Modern day planning of a diamond is done using computer software. Marking – Outlining the best possible shape and cut of the ...
Permanent mold casting is a metal casting process that employs reusable molds ("permanent molds"), usually made from metal. The most common process uses gravity to fill the mold.

Michael Dwyer/Alamy More to the point, can 3-D printing technology help bring all sorts of industries' manufacturing back to American soil? In the jewelry industry, computer-aided design software ...
Affination is a largely obsolete process of removing silver from gold using concentrated sulfuric acid. [4] The Acidless Separation (ALS) has been investigated to pre-refine doré and jewelry alloys even when there is high silver content, which is normally a problem for existing chemical pre-refinement processes. The metals are separated by ...
Generally, the special order jewelers take a design, either their own or a customer's, and turn it into a piece of finished jewelry from start to finish. This process, like model making, can be fairly simple Wax Carving to be cast into metal, or it can involve very complex fabrication skills building the piece out of the actual metal using a ...
