Jewels By Tashne is a family-owned fine jewelry store at 2683 Via De La Valle in Del Mar 92014, operating continuously since patriarch Marv Tashne entered the jewelry trade in 1945. That makes the business nearly eight decades old and one of the longest-running independent jewelers in San Diego County. Kirk Tashne, Marv's son and a Graduate Gemologist from the Gemological Institute of America who also holds a biology degree from UC San Diego, now leads the business. The store specializes in custom-designed engagement rings, diamond bridal sets, estate jewelry, and pre-owned luxury watches from brands including Rolex, Cartier, and Patek Philippe. Kirk works directly with clients to design one-of-a-kind pieces, transforming rough concepts into finished heirlooms set with rubies, emeralds, sapphires, and natural fancy-color diamonds. A master jeweler on-site handles repairs, diamond bezel installations, and watch servicing. Designer collections from Simon G, Michael M, JB Star, Rahaminov, and TI SENTO round out the showroom. The store sits along Via De La Valle just east of Flower Hill Promenade, and shoppers who appreciate fine craftsmanship may also enjoy the fashion-forward accessories at Bon Jewels Boutique nearby for a different price point and style. Jewels By Tashne is open Tuesday through Friday from 10 a.m. to 5 p.m. and Saturday from 10 a.m. to 4 p.m.
