About Us


Geoffrey's Diamonds and Goldsmith was founded in 1984 by Geoffrey Stern and has served the San Carlos community for over 34 years. Geoffrey always held service as his highest priority, and this passion for service was upheld when the company entered its second generation with new ownership under Nikko Kandhari in 2013. Nikko and his team are passionate about fine jewelry and extraordinary customer service. This passion is the central philosophy of how Geoffrey's conducts business, and the central precept of this passion is Geoffrey's strong commitment to excellence in all aspects of the business. In early 2018, Geoffrey's of San Carlos relocated from its longtime home on Walnut Street to a brand-new storefront on Laurel Street.
