The Levi family's presence in San Diego's jewelry trade dates to 1926, and third-generation David Levi & Sons Jewelers now occupies Suite 105 on the ground floor of downtown San Diego's Jewelers Exchange at Sixth Avenue and E Street. The estate-liquidation arm — purchasing gold, platinum, diamonds, Rolex and Cartier watches, and coins — generates referral traffic from estate executors and wealth advisors, including financial planners like Daniel Shahmoradian, CFP in the downtown corridor. On the custom side, in-house CAD modeling and lost-wax casting produce engagement ring settings from concept to finished piece without subcontracting, and every custom order includes lifetime resizing and manufacturing-defect repair as part of the build warranty. Both natural and lab-grown diamonds are stocked in-house, with pre-owned Rolex and Cartier timepieces available through the buying desk for authenticated resale. The full-service model — buying, designing, manufacturing, and repairing under one roof — makes Suite 105 one of the few vertically integrated jewelry operations in San Diego, an end-to-end approach to permanent personal craft that parallels the single-artist start-to-finish custom work at Holy Cobra Tattoo Parlour on the Harborview side of downtown. Highest-value custom commissions involve multi-stone halo and cluster settings using 950-grade platinum stock, with center-stone bezels machined to within 0.1mm of GIA-certified girdle measurements for stones exceeding two carats.
