Established in 2018 in Encinitas's Cardiff-by-the-Sea Cardiff Towne Center, The Diamond Shoppe at 2021 San Elijo Avenue focuses on custom engagement rings, wedding bands, and certified loose diamonds — both natural and lab-grown. The GIA graduate gemologist on staff conducts formal appraisals by appointment, applying the same four-C grading protocol that governs the certified stone inventory, a precision service that complements the event floral consultations at Encinitas Flower Shop during engagement season. Master jewelers handcraft each commission on-site using solid gold and platinum — no gold plating or gold fill — with complimentary engraving included on finished pieces. The lab-grown diamond program offers stones with identical optical, chemical, and physical properties to mined equivalents, expanding the selection for clients coordinating wedding timelines alongside bridal beauty appointments at Noni Salon Boutique Spa. Complimentary shipping with full replacement coverage routes each domestic order in tamper-evident, temperature-neutral packaging.
