Engineered
to last lifetimes.
Crafted to be
worn now.
Two scientists — a roboticist and a neuroscientist — who came home from London to build fine jewellery differently. Gold densified by chemical engineers. Every piece verified by the ATOS Scanner. Designed in London, made in Delhi.

The engineering
behind every piece
Trusted by the finest
watchmakers in the world.
Now in jewellery.
The ATOS Scanner is a 3D measurement system mounted on a robotic arm — the same instrument used by Swiss watch manufacturers to verify the dimensional accuracy of their movement components. At Zefire, we use it to measure every single finished piece against its original design. If a surface deviates beyond ±50–100 microns, the piece is reworked. It never ships out of specification.
Curated Selections
Each piece ships with a Certificate of Engineering. Available in 18kt, 22kt or 24kt — any piece can be customised.
Custom Orders — No Limits
Have a design in mind? Show us your idea and let our sketch artists and craftsmen create a bespoke piece that nobody else has.
Every collection and category at Zefire is available in 18kt, 22kt or 24kt. Yellow, white or rose gold. Any certified gemstone — diamond, sapphire, emerald, ruby, or your choice. The workshop can build it.
Every custom piece goes through the same process as our collections — casting simulation, ATOS Scanner verification, Certificate of Engineering. Custom does not mean compromised. At Zefire it means built exactly to your specification.
"We asked one question: what does jewellery built by engineers actually feel like to wear?"
A brother and sister duo — Aditya with an MSc in Robotics Engineering from King's College London & Aditi with an MSc in Neuroscience from UCL — came home to India not to carry on the family business as it was, but to expand using the skills they learnt. Their biggest motivation and driving force — 'to create jewellery the same way a fine watch is created in Switzerland.' They brought the ATOS Scanner into a jewellery atelier, merged the different skills and technologies to create a new kind of jewellery production environment. They brought chemical engineers into gold casting. They built the first Indian fine jewellery house that treats precision as a specification, not a promise.
Our Commitment
"Jewellery is not decoration. It is heritage in material form."
We believe every piece of fine jewellery should be capable of outlasting the person who first wears it. That requires not just beautiful design, but rigorous metallurgy, precision engineering, and an obsession with the chemistry of gold that most jewellers never think about. At Zefire, engineers and artisans share the same studio floor. The result is jewellery that looks like craft and performs like science.
