Setting the Standard for Service

Our award-winning team of jewelers is trained and certified, led by third-generation family member Tyson Lewis. We are conflict-free and against the importation of conflict diamonds. We fully support and are 100% compliant with The Kimberley Process and The Clean Diamond Trade Act.

We follow a rigid policy that ensures the diamonds we purchase are mined and distributed under the highest ethical standards. We offer a variety of services and specialties for the convenience of our customers, each rooted in values that have been instilled in our family since 1945.

Our team is ready to bring your dream to life, from jewelry repairs and stone settings to intricate designs and custom pieces. Read our story to learn more about how our family business has served the Central Valley for more than 75 years.
