Recycled Metals
All gold and platinum we use is either recycled or sourced from Fairmined-certified operations. We do not work with newly-mined metals from unverified sources.

Built on Mastery.
For over two decades, Jewelry by Masters has created pieces that outlast trends — each one conceived, crafted, and finished entirely in our NYC atelier.

Our Story A Workshop,
A Workshop,
Not a Factory.
Jewelry by Masters was founded on a single conviction: that fine jewelry deserves both the art of the jeweler and the precision of technology. We are one atelier, not an assembly line — and we have never outsourced a single piece.
Every ring, pendant, and bracelet is engineered in 3D and cast as one solid form — the exact weight in its true metal, never parts joined by solder or blanks cut from sheet. Then the master's hand sets every stone and brings the final polish. That union of tool and hand is what we mean by mastery.
"The tool gives the form its precision; the hand gives it its soul. Fine jewelry needs both."
The Atelier 45 Rockefeller Plaza,
45 Rockefeller Plaza,
New York.
Our studio sits adjacent to the Diamond District — the center of gravity for fine jewelry in North America. This location is not incidental: our suppliers, gemologists, and clients are all within reach, and the standards around us are the highest in the industry.
-
Designed in 3D
Every piece begins as a precise digital model, shaped in 3D to micron accuracy. This is the technology that lets us engineer form, proportion, and exact weight before a single gram of metal is poured.
-
Cast in One Piece
The model is 3D-printed and cast as a single solid form — the exact weight in its true metal, never parts joined by solder or blanks cut from sheet. One piece, whole and seamless.
-
Stone Setting
Our master setter has specialized in pavé, bezel, and invisible settings for over fifteen years. Stones are placed by hand under magnification.
-
Final Polish
The last step is always manual. High-polish and matte finishes are applied by hand to preserve the integrity of every surface and edge.
The Craft Two Decades,
Commission a piece
Two Decades,
One Standard.
JBM began with technology, not inheritance. Two decades ago we brought 3D printers, scanners, casting machines, and the first jewelry-design programs into a craft that had barely met them — then learned to design at the bench to match the tools.
That fluency made us teachers to the field's most demanding houses before it made us a brand. Today every piece that carries the JBM mark is engineered in 3D and finished by the master's hand — no work leaves our atelier without that final review.
Where the Craft Was Shared
We trained the houses that define jewelry.
Before JBM was a brand, we taught the world's most demanding ateliers and institutions to work in 3D — the technology and design programs now standard across the trade. Working beside each of them shaped the jeweler we became.

Sustainability
Responsible by Design.
A piece built to last a hundred years is the most sustainable object you can own. We start there, and work backwards.
Conflict-Free Stones
Every diamond is Kimberley Process certified and sourced through GIA-verified channels. For colored stones, we require mine-to-market documentation.
No Waste Production
Metal filings, failed casts, and polishing residue are all reclaimed and returned to the refiner. Our atelier generates near-zero precious metal waste.
Built to Last
We size, repair, and rework any JBM piece for its lifetime at no material charge. A piece that lives for generations never becomes waste.
Local Supply Chain
Our stone suppliers, refiners, and tool vendors are all within the New York metropolitan area. Short supply chains mean lower emissions and faster accountability.
No Fast Jewelry
We deliberately limit production volume. Fewer pieces, made with full attention, is both an ethical and an aesthetic choice — one we are not willing to compromise.
