Why a Physical Prototype
Screen renderings from CAD design are powerful, but nothing replaces holding a 3D prototype. You can try it on, feel the weight and proportion, and spot adjustments that are hard to see on a screen. Many of our NYC clients visit the studio to review the prototype in person; we can also ship it to you for approval. Either way, you sign off on the real shape before it becomes metal.
Wax vs Resin
We produce prototypes using advanced 3D printing in jeweller’s wax or high-resolution resin. Wax is traditional for lost-wax casting: the prototype is invested, the wax is burned out, and molten metal takes its place. Resin prototypes are used for reference and fit checks; when we cast, we may produce a wax from the same CAD file. We’ll recommend the best option for your SKU or line and process.
Detail and Fidelity
Our 3D printers are calibrated for jewellery: fine detail, smooth surfaces and accurate dimensions. Prongs, galleries, milgrain and texture come through so you see what the finished piece will look like. After your approval, the same geometry goes to casting and then stone setting and finishing, so the chain from prototype to jewel is direct.
When We Use a Prototype
Not every project needs a physical prototype. Simple bands or straightforward designs are often approved from CAD alone. For production jewellery, statement pieces or anything where proportion and fit are critical, we strongly recommend a prototype. It’s a small extra step that prevents costly changes after casting. We’ll advise during your trade briefing.
Timeline
Prototype production typically adds a few days to your timeline. We’ll give you a clear schedule when we quote your project. NYC clients can collect the prototype from our Diamond District studio or we can arrange secure delivery. Once you approve, we move straight into casting, no guesswork, no surprises.
