GEM Pawnbrokers traces its roots to 1947, when Martin Kaminsky, a World War II veteran trained as a watchmaker, opened a small pawnbroking storefront that has since grown into a network of 28 branches spread across the Bronx, Brooklyn, Manhattan, Queens, Long Island, and Westchester. The flagship location sits at 230 Flatbush Avenue in Brooklyn, a stretch of the borough with deep roots in the city’s jewelry and pawnbroking trade, and the company still frames its identity around that original watchmaking expertise even as the business has expanded well past its founder’s original single storefront. Nearly eight decades after opening, GEM positions itself as one of New York’s most established pawnbroking businesses, a claim backed less by marketing language than by the sheer number of branches still operating under family and company continuity across five boroughs and beyond.
The core business runs on collateral: customers bring in jewelry, designer watches from brands including Rolex and Omega, fine diamonds, and electronics, and receive cash loans against those items, with the option to reclaim them once the loan is repaid or to sell outright for an immediate payout. Beyond straightforward pawn loans, GEM also handles estate buying, business collateral loans, and vehicle loans, giving it a broader lending footprint than a typical neighborhood pawn shop, and every item that comes through the door for a loan or purchase goes through in-house authentication and appraisal before a number gets attached to it. That authentication step matters most in the jewelry and watch categories, where GEM’s staff evaluate brands like Cartier and Pandora alongside loose diamonds and estate pieces, giving both sellers and buyers a professional read on value rather than a guess.
For customers who prefer not to walk into a branch, GEM also runs retail sales through its own website and a dedicated eBay store, extending its reach well past the neighborhoods immediately surrounding its 28 physical locations. Quotes on items brought in for loan or sale are typically free, and the company emphasizes secure, insured storage for any pledged collateral held during the life of a loan, a detail that matters to customers pawning higher-value jewelry or watches rather than everyday household items. With branches spread across such a wide swath of the New York City area, GEM functions less like a single neighborhood shop and more like a regional financial services chain built entirely around jewelry, watches, and other high-value personal property.
Whether a customer needs a short-term cash loan against a piece of jewelry, wants a professional appraisal before selling a family heirloom, or is simply shopping for an authenticated pre-owned luxury watch, GEM Pawnbrokers offers a long-established, multi-branch alternative across the city. GEM Pawnbrokers is a New York pawnbroking and jewelry business founded in 1947, offering cash loans, estate and jewelry buying, and authenticated designer watch and diamond sales from its flagship Brooklyn location and 28 branches citywide.
