our story

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.

jewelry services

Although we have made a name for ourselves by selling high-quality jewelry, Geoffrey's started as a jewelry repair shop, and we are still dedicated to helping people restore their keepsakes, making even the most damaged pieces of jewelry look new again. Because we know that your jewelry has sentimental value, we will handle it like it's our own, so you can trust us to get the job done right. Our business was originally founded on a reputation of full service, quality repairs. Whether it is ring sizing, stone setting, prong repair, soldering, laser repairs, chain repair, restringing pearls, or any other services, our process and culture of quality control will make sure that you are satisfied with the results. (Medical alerts repaired while you wait.)

Our Services include: Jewelry repair, restoration, resizing, best diamond prices, custom jewelry design, appraisals, diamond grading reports, watch repairs, cleaning & polishing, and buying metals & gemstones...
