San Carlos Jewelers is a women-owned jewelry store in the Navajo Shopping Center at 8736 Lake Murray Boulevard, Suite 110, San Diego, two doors down from Einstein Bros. Bagels in the 92119 ZIP. Owner Shauna and her bench team bring over 25 combined years in the jewelry trade, handling everything from custom engagement ring design and diamond grading to platinum soldering, pearl restringing, and watch battery replacement. The shop sits at the intersection of Lake Murray Boulevard and Navajo Road, anchoring the retail cluster that serves the residential neighborhoods stretching east toward Cowles Mountain and Lake Murray. Engagement ring clients coordinating portraits book Naomi Renée Films & Photography in San Carlos for ring-detail macro shots and couples sessions near the lake. Estate pieces fill a dedicated case near the entrance, rotating through Art Deco platinum-and-diamond rings, mid-century gold bracelets, and vintage gemstone cocktail rings that carry decades of San Diego provenance. Appraisal services cover insurance documentation, estate valuation, and stone identification using a 10x loupe and refractometer to confirm gem species, clarity, and carat weight. The custom design process starts with a consultation sketch, moves to a wax carving or CAD render, and finishes with casting in the client's choice of 14K or 18K gold, platinum, or palladium. Clients insuring newly purchased or inherited pieces coordinate scheduled personal-property riders through Alex Peterson-Cross - State Farm Insurance Agent in San Carlos for coverage that matches the appraised replacement value. Ring resizing, prong retipping, rhodium plating on white gold, and clasp repair all turn around within five to ten business days, with a phone call when the piece is ready for pickup.
