New York Diamond District · Since 1980
Diamonds that shine with you
Natural rarity, PIECUT geometry, lab-grown freedom — one house, three worlds, every piece finished by hand.
The three worlds
Natural. Natural PIECUT. Lab Grown.
Every Jewel Stone piece begins with one decision — the world its diamond comes from. Three worlds, one standard of cut, colour, and character.
I — Earth-formed · One of one
Natural
Formed over a billion years and chosen stone by stone for provenance and individual character. When it is gone, there is no second.

II — The signature
Natural PIECUT
Precisely matched natural diamonds, assembled by hand to read as one larger geometric silhouette.

Family knowledge · since 1980
New name.
Deep roots.
“A diamond will tell you the truth if you turn it slowly enough.”
Jewel Stone is young. The knowledge behind it is not. Since 1980 this family has worked in diamonds — first selecting rough, then cutting, then setting for other houses whose names you would recognise on a boulevard.
What passed down was never a slogan. It was the habit of turning a stone under a lamp until it gives itself away: where the light leaks, where the cut was rushed, which pair will actually match once they sit on a face. That judgment now sits at 47th Street, in a workshop where every Jewel Stone piece is developed, and where Ishan Vaghani still takes the meetings himself.
Three generations of looking closely — in a house that finally carries its own name.
