The Craft Behind Every Piece
More than 50 years of working with diamonds shapes how an RJ House piece is imagined, made, and finished.
From Sketch To Setting
The Craft of an RJ House Piece
Every RJ House piece begins as a sketch, refined over several passes before a single stone is chosen — a sequence that has changed little since our atelier's earliest years, updated only where new tools genuinely improve precision.
- 01
The Sketch
Proportion and light are considered on paper first — refined over several passes before any metal is touched.
- 02
Wax & Cast
The drawing is translated into wax, then cast in responsibly sourced gold, shaping each setting by hand.
- 03
Stone Setting
Certified lab-grown diamonds are set one by one, each seat cut to hold the stone at its most brilliant angle.
- 04
Polish & Inspection
Finished by hand and inspected against the House standard — a piece passes through many careful hands before it reaches you.
Quiet, Not Loud
Our Design Philosophy
We design for the piece that is still being worn in twenty years — not the one that photographs loudest today.
That means proportions that flatter the hand, settings built to be lived in, and a restraint that lets the diamond, rather than the design around it, hold the eye.
Trends inform us, but they do not govern us. An RJ House design is judged by how it wears over time: whether it still feels considered a decade on, and whether it was made with a person in mind rather than a passing moment.
The People At The Bench
Behind the Atelier
Rangani Jewelry House grew out of a family business in diamonds, and much of that spirit remains: a small bench of jewelers, gemologists, and finishers who know a piece by the hands that made it. Skills here are still taught bench-side, one jeweler mentoring the next.
It is slower work than a factory floor, and we have kept it that way on purpose. Every ring, pendant, or pair of earrings passes through people who take responsibility for it personally, from the first wax model to the final polish.
Chosen With Care
Materials and Sourcing
An extraordinary piece should not cost the earth — we choose our materials with that principle in view at every step.
Lab-Grown Diamonds
Chosen for clarity, consistency, and a considerably lighter footprint — selected against the same cut and color standards we have always held.
Responsible Gold
10K, 14K and 18K gold and 925 sterling silver, sourced through responsible channels and hallmarked for purity.
