Custom Jewelry Design & Repair Services in Novato
Valentino Fine Jewelers has been serving Marin County and the San Francisco Bay Area for over 25 years as a family-owned business rooted in three generations of jewelry craftsmanship. Our founder, Mark Singerman, began his journey in the jewelry industry as a goldsmith in the 1980s at Goldpost, which he acquired in 1990 and rebranded to reflect his European design heritage. With more than four decades of hands-on experience in jewelry design and fabrication, we specialize in transforming client visions into custom-designed pieces while maintaining a curated selection of designer jewelry lines. Our commitment to excellence is demonstrated through our in-house repair services, utilization of advanced equipment like laser welders and high-powered microscopes, and a customer-centric approach that prioritizes personalized service.

We guarantee all repair and restoration work, offering regular inspections to protect jewelry investments and employing ultrasonic cleaning technology to restore brilliance to precious gems. Our reputation rests on three pillars: exceptional craftsmanship, trust built through decades of service, and value delivered through transparent processes. As a locally rooted business in Old Town Novato, we combine technical expertise with artistic sensibility to serve both everyday jewelry needs and bespoke commissions.
