At 907 Sixth Avenue in downtown San Diego's Gaslamp Quarter, San Diego Jewelry Buyers operates a four-in-one luxury asset business combining estate jewelry buying, diamond dealing, coin dealing, and collateral lending under a single roof. The firm employs graduate gemologists who conduct complimentary verbal appraisals in private buying rooms, then route purchased items and mail-from-home consignments through carriers like FedEx Authorized ShipCenter for nationwide resale. Collateral loans range from $2,500 to $250,000 on qualified assets including Rolex, Patek Philippe, Vacheron Constantin, Breitling, Harry Winston, Tiffany, Cartier, and Van Cleef & Arpels pieces—with no credit check and no reporting to credit agencies. Four selling channels—direct cash purchase, temporary pawn loan, consignment, and a mail-from-home kit—give clients flexibility based on asset type and timeline. The estate-buying operation evaluates vintage jewelry, luxury watches, and decorative objects from the same secondary-market pipeline that supplies mid-century dealers like Danish Modern San Diego in the East Village. Highest-tier acquisitions involve multi-carat flawless and internally flawless diamond grading, platinum hallmark authentication, and Swiss complication-movement verification on haute horlogerie timepieces.
