Wholesale diamond importing and GIA Graduate Gemologist appraisals define K T Reynolds Co in downtown San Diego's Gaslamp Quarter, operating from the Jewelers Exchange since 1977. The inventory spans GIA, AGS, and EGL-certified loose diamonds in all standard cuts alongside colored gemstones including sapphire, ruby, and emerald—a precious-stone depth that demands the scheduled-article coverage underwritten by carriers like CMR Risk & Insurance Services Inc downtown. Custom design orders move from client consultation through wax model to finished piece, with trade-level pricing available to jewelers and private buyers under the same roof. Full watch repair services cover Swiss mechanical movements for Rolex, Cartier, Chopard, Omega, and Ebel, including complete disassembly, ultrasonic cleaning, and timing regulation on the bench. Nationwide shipping includes overnight insured dispatch for high-value loose stones, extending the Gaslamp showroom's reach to out-of-state trade clients along the same Sixth Avenue corridor that houses the curated selection at Gift Shop on the ground level. Highest-value transactions involve GIA triple-excellent round brilliants exceeding five carats, individually selected for optimal light performance across brilliance, fire, and scintillation metrics.
