OUR MISSION

At Jon Thomas Fine Jewelry, our mission is to create and curate exceptional jewelry that celebrates individuality, craftsmanship, and lasting beauty. We are dedicated to helping our customers mark life’s moments—both big and small—with pieces that are meaningful, masterfully made, and uniquely their own. Through custom design, artisan creations, and thoughtfully selected collections, we aim to offer a personalized experience rooted in trust, creativity, and a passion for timeless elegance.

We are deeply committed to the art of restoration—breathing new life into treasured heirlooms and family keepsakes with the same care and precision we give to every custom creation. Our in-house repair studio ensures that each piece, whether passed down through generations or newly acquired, continues to shine for years to come.

As a locally rooted business, we believe in giving back to the community that has supported us for decades. Through personal service, community engagement, and an unwavering dedication to quality, we strive to be more than a jewelry store—we aim to be a trusted part of your story.

GET TO KNOW OUR STORE!

On October 16, 1993 Jon Thomas opened the doors to Jon Thomas Fine Jewelry located in the heart of downtown Mt. Shasta, CA, a charming mountain community nestled at the base of one of America's most majestic mountains for which the town is named.

As of January 1, 2024, Jon and LesleeRose Thomas gracefully handed over the keys of their legacy to their cherished employees. Committed to preserving Jon's principles and standards of craftsmanship, our team endeavors to continue crafting inspired contemporary pieces and timeless classics, including the revered Mount Shasta Jewelry Collection, ensuring a tradition of excellence for generations to come

"The foundation of fine jewelry is like architecture" Jon explains. "It has to be built correctly, not just beautifully; it has to have a strong foundation. In everything I do, I am striving to complete the vision and expression that was shared with me by the customer."
