Operating from Suite 110 of the historic Jewelers Exchange since 1992, San Diego Jewelry & Loan holds California State Pawnbroker License #3711-0921 and specializes in collateral loans and estate jewelry acquisition in downtown San Diego's Gaslamp Quarter. The ground-floor operation buys, sells, and loans against fine jewelry, gold, diamonds, platinum, and luxury timepieces including Rolex, Patek Philippe, and Cartier—a watch portfolio that overlaps with the secondary-market inventory at Watch AD & Co upstairs in the same building. San Diego Jewelry & Loan is a member of both the San Diego Pawnbrokers Association and the California Pawnbrokers Association, and pays cash on the spot for gold, diamonds, sterling silver flatware, dental gold, and broken jewelry. Beyond pawn services, the shop offers custom jewelry design and on-site repairs, bridging the gap between estate acquisition and new fabrication. The estate-piece inventory rotates alongside collectibles and coins that share a secondary-market audience with shops like Main Street Collectibles in the Gaslamp. Highest-value transactions involve multi-carat certified diamond evaluation, Swiss chronograph movement authentication, and precious-metal assay testing for karat verification on estate gold and platinum holdings.
