Our Story
About Heritage Trading Co.
Heritage Trading Co. is a private diamond, luxury watch and estate buying desk based in Northern New Jersey. It buys estate jewelry, loose diamonds, gold, silver and luxury watches directly from private sellers, families and advisors, and supplies GIA-certified diamonds and authenticated watches to jewelers and dealers across the tri-state area. There is no retail storefront — everything runs by private appointment, with house calls arranged on request.
Heritage Trading Co. serves a rarer kind of client: affluent families, collectors, advisors, and jewelers who want informed buying and selling conversations without the noise of a mass-market retail experience.
Based in Northern New Jersey, we operate at the intersection of wholesale diamonds, authenticated luxury watches, and estate acquisitions. The business is designed around how higher-trust transactions actually happen — by referral, by appointment, and with a strong preference for privacy, preparation, and clear communication.
Clients come to us from across Bergen County — Ridgewood, Paramus, Saddle River, Alpine, Tenafly, Englewood Cliffs, Wyckoff and Mahwah among them — as well as Passaic, Essex and Hudson counties, and the wider New York and Connecticut market.

What makes the approach different
We do not treat diamonds, fine watches, or estate pieces like anonymous shelf inventory. Every conversation starts with fit: what the item is, who it is for, what the paperwork says, how the market is moving, and whether the best next step is a direct purchase, a private showing, or a curated weekly release.
That makes Heritage especially well suited to the demographics across Northern New Jersey and the wider New York metro market — clients who value a calm process, well-reasoned guidance, and counterparties who understand both luxury and liquidity.
How we work
On the buy side, we share inventory editorially and privately rather than pushing a noisy, retail add-to-cart experience. On the sell side, we provide direct estate buying guidance, transparent comparisons against auction and consignment routes, and private appointments for clients who want a more discreet path.
