Our Story

Since 1977, Peninsula Gem and Jewelry has been a cornerstone of our community, born from John Green’s passion for jewelry and the creative arts. What began as a personal pursuit has grown into a trusted, family-owned jewelry store known for craftsmanship, care, and connection. From restoration and engraving to laser welding, casting, and custom design, we blend time-honored traditions with modern innovation. We are proud to source gemstones ethically and responsibly—including the famed Big Sur Jade, local to the Monterey area—and to create custom pieces that turn every design into a story worth telling. For nearly five decades, we’ve helped collectors and gift-givers alike preserve cherished memories and create new ones through jewelry that endures.

Customer Testimonials


I had an idea on a design for a ring. I went to Peninsula Gem & Jewelry and was helped by Kris who took his time in listening to my ideas. His knowledge and expertise was crucial in making a beautiful ring come true. I love this piece of jewelry and thank Kris and family for being so friendly and caring. I highly recommend Peninsula Gem & Jewelry Supply.

PG&JS has been my go to place when needing jewelry repaired. Today I picked up my wedding band that needed to be resized. I have brought earrings in to be repaired or altered, heirloom pieces that need some loving attention. Each time, I am treated with friendly professionalism. I appreciate their expertise, thoroughness, and attention to detail. I would highly recommend using their services.
