AI Tool for Kundan Jewellery Design — Complete Guide (2026)
Facetra is the AI tool built for Kundan work — scalloped 24kt gold edges, silver-foil-backed Polki chatons, meenakari reverse. Ateliers in Jaipur, Amritsar, Hyderabad use it to collapse sketch-to-CAD from 4-7 days to same day at ~₹256 in credits.
A working Kundan atelier has one bottleneck: the sketch-to-client-approval cycle. A designer sketches a piece, an outsourced renderer takes 2–3 days, the client asks for revisions, and the loop restarts. Facetra collapses that loop to minutes with an AI rendering engine that is specifically tuned for Kundan work — scalloped 24kt gold edges, silver-foil-backed Polki chatons and meenakari reverse.
Why generic AI image tools fail on Kundan
Ask Midjourney or Stable Diffusion for "Kundan necklace" and you will get a decorative gold-and-red image that looks nothing like real Kundan work. The reason:
- They do not understand Kundan-setting geometry. Real Kundan has a raised, scalloped 24kt gold border where the goldsmith pressed the foil around the stone with hand pressure. Generic models paint a smooth gold ring around the stone.
- They do not know Polki is uncut, foil-backed diamond. Generic models render bright sparkle where Polki should have soft, diffuse glow.
- They do not preserve iconographic proportion. A Rani Haar has a specific seven-panel construction; generic models produce random ornament.
- They cannot produce multi-view sheets. Even if the first render looks acceptable, there is no way to hand it to a CAD operator.
How Facetra renders authentic Kundan
Facetra's prompt library was co-developed with three Jaipur-based Kundan ateliers. It understands the specific vocabulary — chaton, kundan-set, meena reverse, Rajwadi finish, jaali shoulder, ghungroo drop, bali, aad, rani haar, chandbali — and produces renders that match what a karigar would actually build.
Behind the render sits Gemini 3.1 image generation, prompt-engineered with a specialist system prompt that carries Indian jewellery craft knowledge as context. We chose Gemini because it produces more faithful reproductions of small metal-edge detail than Midjourney or DALL-E — critical for Kundan scalloped edges.
The seven-step Kundan workflow
- Sketch upload. Photograph the client's paper sketch on your phone — Facetra reads pencil, ballpoint and marker equally well.
- Prompt. Describe the piece in one sentence — "18-chaton bridal Kundan Rani Haar with green meenakari reverse, seven-panel construction, 22kt gold".
- Render. 40-60 seconds. Multiple stone-colour variations at 1 credit each.
- Lasso refine. Mark a region ("this centre chaton") and describe a change ("swap for oval Polki"). Only that region re-renders. No proportion drift.
- Multi-view sheet. Silhouette-locked 0° / 45° / 90° / 180° views for the CAD bench.
- Bare-metal + BOM. Strip stones and enamel to see the casting geometry; auto-generate a Bill of Materials at today's 22kt Zaveri Bazaar rate.
- 3D mesh. GLB / STL / OBJ / FBX / USDZ / 3MF for retopology in Rhino or MatrixGold.

- "Heavy bridal Kundan Rani Haar, 18 uncut Polki chatons, green meenakari reverse work, 22kt gold, scalloped kundan edges, product photography, matte black backdrop"
- "Kundan Bali earring pair, teardrop Polki centre, ruby drop, jaali-work shoulder, gold foil backing visible, macro lens, studio lighting"
- "Kundan Chandbali, crescent silhouette, seven Polki chatons, ghungroo drops, meenakari peacock motif on reverse, 24kt gold finish"
What it saves an atelier
Per-piece comparison for a typical bridal Kundan Rani Haar:
| Stage | Traditional | With Facetra |
|---|---|---|
| Client-approval render | 3-4 hrs hand-render + ₹2,000-5,000 outsourced | 60 seconds, 1 credit (~₹12) |
| Two revisions | 3 more days round-trip | 2 lasso edits, 2 credits, 3 minutes |
| Multi-view for CAD bench | 2-3 hrs, ₹500-1,500 outsourced | 1 click, 4 credits (~₹48) |
| BOM at live gold rate | 30-60 min manual calculation | Auto-generated, 1 credit |
| 3D mesh for CAD retopology | 1-2 days outsourced, ₹3,000-8,000 | 2-3 minutes, 15 credits (~₹180) |
| Total sketch-to-CAD-ready | 4-7 days, ₹5,500-14,500 | Same day, ~₹384 |
Where Facetra fits alongside your CAD bench
Facetra is not a replacement for MatrixGold or Rhino. Those tools model manifold cast-ready geometry — that is what a CAD operator retopologizes for casting. Facetra sits upstream: it produces the design references (renders, multi-view sheet, BOM, 3D mesh) that a CAD operator uses as input. See our MatrixGold vs Rhino vs Facetra article for the full breakdown.
