Our heritage

A private-market desk headquartered in Northern New Jersey

Heritage Trading Co. is built for a clientele that values privacy, speed, and judgment. We work at the intersection of wholesale diamonds, authenticated luxury watches, and high-trust estate buying for families, advisors, and the trade throughout Northern New Jersey and the surrounding towns.

That means a quieter experience than public marketplaces: private appointments, disciplined disclosure, and direct conversations around quality, paperwork, memo, valuation, and timing. For the right clients, that is exactly the point.

Straight answers

The questions we are asked most

Short, direct answers for anyone weighing up whether to sell a piece or open a trade account — no forms required to read them.

What is Heritage Trading Co.?
Heritage Trading Co. is a wholesale diamond, luxury watch and estate jewelry dealer based in Northern New Jersey. It buys estate jewelry, loose diamonds, gold, silver and luxury watches directly from private sellers, and supplies GIA-certified diamonds and authenticated watches to jewelers, dealers and private clients across the tri-state area.
Where is Heritage Trading Co. located and what areas does it serve?
Heritage Trading Co. is based in Northern New Jersey and serves Bergen County towns including Ridgewood, Wyckoff, Franklin Lakes, Paramus, Englewood, Fort Lee, Tenafly, Hackensack, Saddle River and Alpine, along with Passaic, Essex and Hudson counties and the wider New York and Connecticut tri-state market. Meetings are by private appointment, and house calls are arranged on request.
What does Heritage Trading Co. buy?
Heritage Trading Co. buys estate and antique jewelry, loose diamonds, signed pieces from houses such as Tiffany & Co., Cartier and Van Cleef & Arpels, gold and silver jewelry, and luxury watches including Rolex, Omega, Cartier and Patek Philippe. Single pieces are welcome; there is no requirement to have a collection, a certificate or any trade background.
Does Heritage Trading Co. charge fees or commissions to sellers?
No. Heritage Trading Co. charges no seller fees, no commissions and no deductions of any kind. Valuations are free and carry no obligation, and there is no charge if the seller declines the offer and keeps the piece. This differs from auction and consignment routes, which typically deduct between 10 and 50 percent of proceeds.
Does Heritage Trading Co. have a walk-in store?
No. Heritage Trading Co. works by private appointment rather than from a retail storefront, which is why sellers are asked to make contact first. Appointments are arranged across Northern New Jersey, and a senior buyer can travel to a home or office on request. Call or text +1 (845) 459-0385 or use the scheduling calendar to arrange a time.
Why is an insurance appraisal higher than the offer to buy a piece?
An insurance appraisal states replacement cost — what it would cost to buy a comparable piece new at retail, including retail margin. Resale value is what the piece trades for on the secondary market today. The two figures are calculated for different purposes and are almost never the same number. Heritage Trading Co. explains how an offer is built, factor by factor, so the difference is visible rather than assumed.
How long does selling jewelry to Heritage Trading Co. take?
Selling directly is typically far faster than auction or consignment, which can run weeks to months. A seller shares the basics of the item, receives a no-obligation view shaped by current wholesale demand, then meets privately if it makes sense to continue. Payment follows promptly once terms are agreed.
Can jewelers and dealers buy wholesale from Heritage Trading Co.?
Yes. Heritage Trading Co. supplies GIA-certified single diamonds, calibrated melee and small parcels, Old European and antique cuts, matched pairs and fancy shapes, plus authenticated luxury watches. Approved trade accounts receive a weekly inventory list with stone-by-stone certificate numbers, net pricing and current memo terms. Trade access is granted by application.
