What we offer

 Sonora Jewelry is a full service jewelry store specializing in custom design and repair. We have been a family business since 1979.  We have featured a vast array of high quality and affordable fine jewelry since day one.  


Our custom design service works with your ideas to create a one of a kind creation by using visual 3D images and wax models.  The 3D image allows for easy modifications while the wax model shows the exact design checking for perfect fit and proportions before manufacturing.  Our passion for excellence has driven us from the beginning and continues to drives us into the future.  Our team at Sonora Jewelry knows that each and every customer interaction counts and we strive to make their entire shopping, designing or repairing experience as rewarding and fun as possible.
