Derco Fine Jewelers

Derco Jewelers has proudly delivered top-quality diamonds and fine jewelry at outstanding prices, with a level of service that stands above the rest. Founded in 1939 by Krikor (Koko) Der Abrahamian and based in San Francisco since 1979, Derco has built a devoted clientele rooted in the Bay Area and extending nationwide and globally.

Our experienced team of gemologists, goldsmiths, and jewelers – many of whom have been with us since our San Francisco showroom opened over 30 years ago?has played a key role in fostering long-standing customer relationships. Focused on exceptional service and premium craftsmanship, Derco has grown steadily thanks to word-of-mouth and loyal referrals. Still family-owned, the business is now led by brothers Jack and Ohan Der Abrahamian, who carry on their father’s tradition.

Diamonds have been our family’s passion for generations. Our online collection features one of the largest selections of diamonds, sourced from trusted vendors worldwide. Thanks to the high volume of our operations and our rigorous standards, we are able to offer unmatched variety, quality, and value.
