The maison · New York Diamond District

A new name, on deep family roots.

Jewel Stone grows from a family jewelry business operating since 1980. That experience now guides every stone we select and every piece we make in-house.

The founder

Three generations at the bench.

Ishan Vaghani

Founder & Diamond Consultant

Our family jewelry business began in 1980, and the trade passed down hand to hand across three generations. Ishan Vaghani carries that knowledge into Jewel Stone today, overseeing each piece from stone selection and first sketch through setting and final finish.

Work stays in-house — design, casting, setting, and finish. No mass production, no anonymous catalogue story. Just carefully chosen stones, honest grading, and judgment built over more than forty years.

Manufacturing · scratch to finish, in India

  • Prakash VaghaniManufacturing
  • Mitul ShihoraManufacturing

Prakash Vaghani and Mitul Shihora run our workshop in India end to end — from rough and cutting through casting, setting, and final finish — so every Jewel Stone piece is made under one roof, start to finish.

Family knowledge · since 1980

Forty years of looking closely.

“A diamond will tell you the truth if you turn it slowly enough.”
1980

The family enters the diamond trade — first selecting rough, then cutting and setting for houses you would recognise.

Since

Three generations of judgment passed hand to hand: how a stone leaks light, how a pair truly matches on a face.

Today

Ishan Vaghani carries that knowledge into Jewel Stone at 47th Street, overseeing every piece himself.

Three diamond worlds

Different origins. One standard of judgment.

Whichever world a piece comes from, it meets the same eye for cut, colour, and character.

I

Natural

Selected for rarity, proportion, and individual character — certified stones with geological provenance, chosen one at a time.

II

Natural PIECUT

Precisely matched natural diamonds assembled by hand into one larger geometric silhouette. Our most distinctive design language, found nowhere else.

III

Lab Grown

The same crystal structure and optical performance, with more freedom in scale, grade, and budget — made to order in every metal.

What we stand for

Three quiet rules.

01

One of one

Every signature piece is made a single time. When it sells, it is gone — no reorders, no duplicates.

02

Stone first

We start from the diamond, chosen for proportion and character, then build the setting around it.

03

Made to be worn

Finished to order in rose, white, yellow gold, or platinum — sized and insured. Heirlooms, not display pieces.

Come see them in person.
