Gems of La Costa in Carlsbad's La Costa district provides custom jewelry design, certified diamond sales, and on-premises repair from Suite 105 in the Plaza Paseo Real center at the intersection of El Camino Real and Aviara Parkway, serving the community since 1989. Four master jewelers with over 120 years of combined bench experience work on-site, handling everything from CAD-rendered engagement rings to hand-fabricated one-of-a-kind settings—a depth of in-house craftsmanship that extends naturally into the bridal-preparation services offered at Ocean Day Spa nearby in the La Costa corridor. Founded by Dale and Linda Condy and now operated by master jeweler Chad Elliott—who also owns Oceanside Jewelers—the store maintains graduate gemologists on staff for diamond grading, colored-stone identification, and insurance appraisals. The shop is an official dealer of Dora International wedding bands, which combine gold, titanium, platinum, palladium, and diamonds in mixed-metal ring designs manufactured since 1994. Watch repair covers battery replacement, crystal fitting, and band adjustment, while gold-buying services price scrap and unwanted pieces against the daily spot market for immediate cash payment—a same-day liquidation speed that pairs with the event-day floral coordination at Studio Fleurish for time-sensitive wedding projects. The most technically demanding custom commissions use CAD software to preview three-dimensional renderings before lost-wax casting, enabling clients to approve prong placement, gallery height, and stone orientation prior to metalwork.
