About the house

Three generations in the parcel trade.

A dealer, not a storefront — Atlantic Gem sources, matches and sells natural colored stones to jewelers and designers, not the public.

Founded in 1973 on West 47th Street, Atlantic Gem Corp has spent five decades doing one thing: finding exceptional natural sapphire, ruby, emerald and alexandrite, and matching them into pairs and parures precise enough for a bench jeweler's eye.

Every stone that leaves our office is natural and untreated or disclosed as treated — we deal in origin, clarity and colour, not synthetics. Clients come to us for singles as often as for the harder problem: a pair, or a suite, matched for tone and size to the tenth of a millimetre.

We sell strictly to the trade — retailers, designers and fellow dealers — from our office in the heart of the Diamond District.
