From Hand-Sketching to CAD: How Technology Is Reinventing an Ancient Craft
For over 5,000 years, diamond jewellery has been crafted by hand — sketches on paper, wax carvings shaped by skilled artisans, and stones set under magnifying loupes. But in the last decade, the industry has quietly undergone one of the biggest technological transformations in its history.
As a diamond jewellery manufacturer based in Mumbai with 20+ years in the industry, we have seen this shift firsthand. What used to take weeks of back-and-forth between designers and clients can now be prototyped in hours. What was once limited by an artisan's imagination can now be modelled, tested, and refined in 3D before a single gram of gold is cast.
This article breaks down the modern tech stack behind premium diamond jewellery manufacturing in 2026 — and why it matters even if you have nothing to do with jewellery.
The Modern Diamond Jewellery Tech Stack
- CAD (Computer-Aided Design)
Software like Rhinoceros 3D, MatrixGold, JewelCAD, and 3Design has replaced paper sketches for almost all modern jewellery design. Designers can:
- Build a piece in 3D with sub-millimetre precision
- Test how a diamond will sit in its setting before any metal is cut
- Generate photorealistic renders for client approval
- Share files instantly with manufacturing units worldwide
The result: fewer errors, faster iterations, and designs that are far more intricate than what was possible by hand alone.
- 3D Printing (Wax & Resin)
This is where the magic happens. CAD files are sent to specialised wax 3D printers (DLP, SLA, or material jetting) that print the design in castable wax or resin.
Popular machines in modern jewellery studios include:
- EnvisionTEC Perfactory**
- Solidscape S500**
- Formlabs Form 3+** with castable resin
Why it matters: A design that would have taken a master wax-carver 40+ hours can now be 3D-printed in under 6 hours — with greater precision and zero human fatigue errors.
- Lost-Wax Casting (The Traditional Step That Stays)
After printing, the wax model goes into an investment mould, the wax is burned out, and molten gold or platinum is poured in. This part of the process has stayed largely unchanged for centuries — and that is part of its charm. Some traditions are worth keeping.
- Laser Welding & Soldering
Laser welding machines now allow jewellers to make incredibly precise joins, including next to heat-sensitive gemstones that would have been destroyed by traditional flame soldering. Brands like Orion and Rofin dominate this category.
- Automated Stone Setting (Selective)
While most premium diamond setting is still done by hand, certain types — like channel-set diamonds in tennis bracelets or pavé settings — are increasingly assisted by micro-setting machines with computer-guided drilling.
6. AI-Assisted Design Tools
This is the newest frontier. Tools like **MatrixGold's AI plugins, Vectary, and even generative AI models are being used to:
- Generate hundreds of design variations from a single brief
- Predict customer preferences from sales data
- Suggest setting optimisations to maximise diamond brilliance
We are still early in this space, but the next 2-3 years will likely change how design briefs are translated into final pieces.
- Digital Imaging & Photography
Once a piece is complete, it goes through 360° photogrammetry for online catalogues. Tools like Ortery, PackshotCreator, and now AI-based background removal allow manufacturers to produce e-commerce-ready images at scale.
What This Means for the Industry
Three big shifts are happening:
Faster time-to-market:** A new collection that used to take 6 months from concept to inventory can now ship in 6-8 weeks.
Lower barriers to customisation:** Bespoke and custom-design jewellery is no longer a luxury reserved for ultra-high-end buyers — manufacturers can now offer custom CAD work at competitive prices.
Better quality control:** Computer-generated models eliminate many of the inconsistencies of pure hand-craftsmanship, especially for retailers buying in bulk.
At Ariha Diamonds, we have integrated most of this stack into our Mumbai facility — combining 20+ years of artisan expertise with the precision of modern CAD, 3D printing, and quality-control tech. The result is jewellery that is faster to deliver, more consistent, and more design-forward than what was possible even a decade ago.

Why Developers Should Care
You might be wondering — why is this on Dev.to?
Because the diamond jewellery industry is now hiring developers, 3D modellers, and AI engineers. The next generation of jewellery tech will be built by software people. CAD plugin development, AI-assisted design tools, AR try-on experiences, blockchain-based diamond provenance tracking, automated inventory systems for retailers — all of these need engineers.
If you are a developer interested in this space, the design-meets-manufacturing intersection is one of the most underexplored areas in tech right now. There are open opportunities in:
- AR/VR try-on apps** for online jewellery retailers
- AI-based design generation** specific to jewellery aesthetics
- Blockchain provenance** tracking for ethical sourcing
- ERP and CRM systems** designed for the jewellery trade
Final Thoughts
The diamond jewellery industry is a fascinating case study in how an ancient craft adapts to modern technology — keeping what works (hand-finishing, artisanal stone setting) and modernising what doesn't (sketching, prototyping, photography).
For us at Ariha, the technology is never the point — the jewellery is. But better tools make better jewellery possible at scale, and that is what allows us to serve 200+ retailers across 10+ countries with consistency and care.
