Diamond & Gold Buyer San Diego occupies Suite 502 in the Colonel Fletcher Building at 624 Broadway in downtown San Diego. The firm's appraisal and purchasing services cover loose diamonds graded across the full 4C spectrum (cut, clarity, color, carat), gold in purities from 10K through 24K, and estate jewelry — a secondary-market expertise shared by GIA-trained setters like Brilliant Diamonds Fine Jewelers in the nearby Jewelers Exchange. Beyond buying, the firm designs custom engagement rings and wedding bands using conflict-free diamonds sourced through Kimberley Process-certified channels. Custom jewelry repair and resetting services allow sellers to repurpose inherited stones into new designs, an artisan-craft approach to estate assets distinct from the cocktail-bar ambiance at Craft & Commerce but anchored in the same Broadway corridor. Highest-complexity commissions involve resetting antique European-cut and mine-cut diamonds into modern prong and bezel mountings fabricated in 14K or 18K white gold and platinum.
