Jewel Cast

As its name suggests, Jewel Cast has perfected the art of designing and casting custom jewelry designs using precious metals. First, its designers use multiple versions of CAD to develop highly detailed jewelry designs and renders. Such detail is vital as it enables you to make informed decisions on whether a design meets your vision and other requirements. 

Once all design details are finalized and you confirm your custom jewelry order, the production team takes over and begins the jewelry casting process. They first create moulds identical to the design and then pour molten metal into them in controlled factory conditions. When the metal cools and solidifies, it takes the shape of the mould, which is the actual jewelry design.

Jewel Cast can currently cast 1000 jewelry pieces a day. It uses 18ct, 9ct, and 14ct gold, palladium, and sterling silver. After casting, most of the jewelry is perfected by hand to ensure every part is flawless and meets the company’s exacting quality standards.

Artisans use automated machines when creating moulds and casting jewelry, for instance, but perform other processes, like jewelry mounting, by hand.

It prioritizes ethical and sustainable material sourcing. The latter includes using recycled gold and silver, but this does not impact the quality or value of the jewelry in any negative way.
