About Valentino Fine Jewelers

Valentino Fine Jewelers proprietor Mark Singerman is a third-generation jeweler, designer, and artist who has been serving customers in Marin County and the greater San Francisco Bay Area for more than 25 years. His passion for his craft was instilled at an early age when he would spend time in his grandfather’s jewelry store, watching him work with the glittering elements of his craft—the gold and precious stones. “When I was a kid, I remember so clearly being in my grandfather’s store and seeing the delighted reactions of his customers when he would present them with a custom-designed piece of jewelry.” Mark is dedicated to building on his family’s legacy. He brings more than 40 years of design and fabrication experience to each project. He is a customer-focused design and creative consultant who works closely with his clients to bring their vision for a custom piece of jewelry from concept to completion. Mark also uses his refined sense of design and quality to research and procure the designer lines of jewelry he carries in his store.

Valentino Fine Jewelers was formerly known as Goldpost, where Mark Singerman worked as a goldsmith in the 1980’s. In 1990 he bought Goldpost and renamed it Valentino Fine Jewelers to reflect his European design style.
