Do I need to know jewellery terms?

No. Say what you see: “bigger stone”, “thinner band”, “rose gold”. The AI maps it to the right operation and explains what it changed.

Export the STL and spec sheet for any workshop; Kubikly does not manufacture.

Can you tell the karat or the gemstone from a photo?

No, and we never claim to. Karat, gemstone identity and weight cannot be read from an ordinary photograph. The studio labels such values as AI ESTIMATED and lets you enter what you know; the weight estimate is calculated from modelled volume and the alloy density you choose.

How accurate is the gold weight?

As accurate as the geometry. With a ring size or one measurement the range is typically within ±8–12%; hidden metal under stones and hollowed shanks widen the range, which we show explicitly.

Free to start

Design a ring by talking, free

Start from a photo you like or from the demo solitaire. Say “1.5 ct oval”, “six prongs”, “14K rose gold”, “add a pavé halo” and watch the model, the gold weight and the price change. The first model is free and so is every edit.

Real geometry

Band, setting, prongs, halo, stones and chain as parametric parts; STL export for casting when you are ready (credits).

Weight and price as you go

The metal-weight table for every karat and the price for your country update with each change.

Free where it counts

First model, unlimited edits, three projects. Renders, exports and appraisals are the paid extras.

How it works

1
Upload photos
One or more angles of a ring, pendant, chain or bracelet; sketches and renders are fine.
2
AI models the construction
Band, setting, prongs, halo, stones and chain links are rebuilt as parametric geometry.
3
Calibrate
Give the ring size or one measurement; optionally the karat and stone details.
4
Edit by talking
“18K rose gold”, “2 carat centre stone”, “band 0.4 mm thicker”, “show it with emeralds”.
5
Weight, price, export
Volume-based gold weight for every karat, the day’s metal value in 25 currencies, STL for casting.

Design tools for jewellery are either a sketchpad or a CAD suite. This is neither: the model is real CAD-grade geometry, and the interface is a conversation.

From design to a jeweller

Export the STL and the spec sheet (gem report, metal weights, overall length) and hand them to any workshop; the To-be-made price tells you what a fair quote looks like in your country.
