Established in 1984 by Nasser and Mali Digius, Diamond Boutique is a family-owned jewelry store at 2710 Via De La Valle Suite B-280, Del Mar, CA 92014, with over 40 years of history serving San Diego's coastal communities. The shop moved into its current custom-built location in 2007 and holds membership in the American Gem Society — placing it in the top five percent of jewelers, designers, and appraisers nationwide. On-staff GIA graduate gemologists guide clients through engagement ring selection, wedding band design, and custom commissions, while the in-house team handles jewelry repair, appraisals, and complimentary professional cleaning and inspection every six months. Couples shopping for engagement rings along the Via De La Valle corridor can stay nearby at the Hilton San Diego/Del Mar and make a weekend of it. Designer wedding band collections include pieces from Furrer-Jacot, Christian Bauer, Gelin & Abaci, Novell, and Wright & Lato, alongside Diamond Boutique's own artisan creations. The store is known for carrying the EightStar Diamond, marketed as the most precisely cut round brilliant in the industry. Beyond the display cases, the Digius family has donated to more than 500 San Diego charities including Rady Children's Hospital, the American Heart Association, Make-A-Wish Foundation, and Dress for Success. Diamond Boutique maintains an A+ rating with the BBB, accredited since 1997. The pet-friendly showroom welcomes dogs, and the staff is happy to pour you a cup of tea while you browse — a personal touch that keeps multi-generational families returning. Brides-to-be coordinating rings and gown fittings in one trip can also visit Elegant Tailor and Cleaners on Camino Del Mar for expert wedding dress alterations. Hours are Tuesday through Saturday 10:30 a.m. to 5 p.m. and Sunday 11 a.m. to 4 p.m., closed Monday.
