New York's Diamond District concentrates the U.S. diamond trade onto a single stretch of West 47th Street, where grading labs, buyers, and appraisal expertise sit within a block of one another. For a jewelry-backed loan, that proximity shapes how a valuation is built and verified.
New York's Diamond District runs a single dense stretch of West 47th Street, and it operates at a scale no other American market matches. It is home to more than 2,600 businesses, employs 33,000 people, and sees an average of $400 million in daily transactions on the way to roughly $24 billion in annual sales. It is the largest diamond exchange in the world by transaction volume, and by the New York City Economic Development Corporation's estimate it processes about 90% of the rough and polished diamonds entering the United States. For a desk lending against jewelry, that concentration is not trivia: appraisal, market comps, and buyers all sit within walking distance of one another.
The Gemological Institute of America, the primary diamond grading authority, keeps its New York City campus at 50 W 47th Street, Unit 800, inside the district itself. A second major lab, IGI, runs a Midtown Manhattan office close to 47th Street, so a stone can reach two recognized labs on the same blocks. The district was partly built for this work: a single building at 580 Fifth Avenue houses over 200 separate jewelry-related tenants, and the Gem Tower at 50 West 47th Street, a 34-story structure completed in 2013, was purpose-built for diamond and jewelry businesses.
That matters because a GIA report is independently checkable: any grading report can be confirmed through GIA's online Report Check service at gia.edu/report-check, which verifies that a physical document matches GIA's own database record and has not been altered. For asset-backed lending, that verifiability is the point. A report you can confirm against the issuing lab narrows the gap between what a piece is claimed to be and what it can be lent against. Bringing your GIA or IGI documentation, along with any purchase records, gives a review a firmer starting point, though the stone is always examined on its own terms.

A collateral loan in New York runs under General Business Law §46. No collateral loan broker may ask, demand or receive a greater rate of interest than four per centum per month, or any fraction of a month — a legal ceiling, not a quoted rate. The same statute allows a minimum interest charge of twenty-five cents per month, and bars any interest or charges on a loan for a period exceeding fifteen months from the date the loan was made, unless the pledgor directly requests an extension.
Licensing here is a city function. The New York City Department of Consumer and Worker Protection issues the pawnbroker, or "collateral loan broker," license defined in GBL §52, and the fee for the full one-year license term is $500. State law also governs default timing: pledged property not redeemed within thirty days following the maturity date is addressed by statute, and the transaction form must disclose an APR computed under the federal Truth in Lending Act along with the total-of-payments figure.
The §46 ceiling leaves room below it. One local operator, New York One Pawn, posts four-month collateral loans at a monthly rate between 2% (24% APR) and a maximum of 4% in line with state law. That is one desk's posted structure, offered here only to show how the statute plays out — not a market-wide rate, and not a figure we are quoting you.
Loans are originated by licensed lender partners operating under the New York framework above. Every rate, term, and threshold on this page is general guidance drawn from statute and published operator terms; it is not a loan offer, an appraisal, or a promise of approval or payout. A specific figure follows an inspection of your piece and any accompanying grading documents. You can read how the process runs from intake to redemption, or start a confidential conversation with us.
Loans are originated by licensed lender partners. Loan offers, terms, rates and final decisions are made by the originating licensed lender at appraisal — figures shown here are general guidance, not loan offers.
