About Us

For over 24 years, Gemma’s Jewelers has been a cherished part of Southern California’s jewelry landscape — a true family legacy built on craftsmanship, trust, and community.

It all began in 2001, when Margarita Pereda opened the first Gemma’s Jewelers in Rancho Cucamonga, Ca. With a passion for fine jewelry and a commitment to personal service, Margarita turned a small storefront into a destination for timeless pieces and heartfelt connections.

As the family grew, so did the business. In 2012, we opened our Eastvale location, carrying forward the same values of integrity and precision that define our brand. That location is run by her son Robert, an expert watchmaker, Then in 2021, the family expanded once more, acquiring a long-standing jewelry store in Mission Viejo, now led by Amy, Margarita’s daughter — a distinguished designer and GIA Graduate Gemologist whose artistry and expertise shine through every creation.

Together, we’re proud to serve generations of families, offering everything from exquisite diamonds and fine jewelry to bespoke designs and expert watch and jewelry repairs.

At Gemma’s Jewelers, we believe every visit should feel like coming home — warm, personal, and unforgettable.

We love what we do and we do it with passion. We sincerely hope to inspire you. If you want to check out our blog, please do so here.
