We Love What We Do


Kevin Main’s lifelong passion for creating fine jewelry and providing people with beautiful pieces that commemorate the special moments in their lives is reflected in his craftsmanship and that of the designers represented at Kevin Main Jewelry.

The only American Gems Society certified gallery in San Luis Obispo, with an accredited jewelry appraiser on staff.


Custom Design & the Gallery

Kevin Main Jewelry had humble beginnings, opening in 1973 as a small, one-man silver shop in the quaint beachside community of Morro Bay, California. Here, Kevin Main sharpened his skills as a designer, craftsman, and businessman while building his glowing reputation across San Luis Obispo County. In November 1998, Kevin and his wife Kathi decided to expand their business into San Luis Obispo. Today the showroom at Kevin Main Jewelry, with its pristine original hardwood floors and its rustic brick walls, is thriving right in the heart of Downtown San Luis Obispo. Kevin Main Jewelry offers a great selection of Kevin Main original designs crafted by the owner himself, as well as a wide range of pieces by various internationally recognized designers, and features a full-scale repair shop and custom design studio on-site.


The Craft Is in the Craftsman

Kevin is a self-taught jeweler and craftsman with over 40 years of experience as an artist. His commitment to honest, quality products and service underpins the success Kevin Main Jewelry has found today. Kevin is always seeking ways to make things better and more beautiful, and to evoke a memorable experience in everything he creates. When he’s not working at his jeweler’s bench he is probably tallying miles and memories cycling. His passion for ultra-distance cycling has taken him far and wide throughout the United States and internationally. He also loves to go for walks with his wife Kathi and faithful mascot Bixby the poodle and enjoys playing with his adorable grand kids when they come to visit.

The domestic violence intervention movement began in America in the early 1970s. What has become the Women’s Shelter Program of San Luis Obispo (WSP) started in 1977 with two women in Morro Bay who opened their home to women fleeing domestic violence. From there, other volunteers joined them in their effort to provide safety to victims. In 1979, this volunteer effort became formally incorporated as the Women’s Crisis House. As services expanded for domestic violence victims, the Women’s Crisis House changed its name to Women’s Shelter Program of San Luis Obispo County in order to reflect the expansion of these services. The Women’s Shelter Program now has a wide range of programs available to victims of intimate partner violence and child abuse including emergency housing, transitional housing, advocacy, legal services, counseling, community education, Latina services, and children’s services.


BMVSS, which manages Jaipur Foot, depends entirely on donations and whatever government grants it can secure. The costs of the limbs, boarding and food are completely absorbed by Jaipur Foot.
More than 65,000 people are helped every single year through the organization and, while similar artificial limbs can cost as much as $10k in the US and in the United Kingdom, Jaipur Foot produces each limb for about $70, thoroughly maximizing every dollar donated.
Jaipur Foot has a working relationship with Stanford University and MIT for research and development. One such project resulted in the Stanford Knee, hailed as a major breakthrough in orthopedics.
