H Tim Williams Jewelers

H Tim Williams Jewelers is a jewelry store in Santee, CA. The shop is known for custom jewelry design, colored gemstone work, and on-site diamond and gem grading, and it serves customers across the East San Diego area from its storefront on Mission Gorge Road.

The business was founded by Tim Williams, who, along with Robin Williams, ran the Santee location for over 20 years and worked in the jewelry trade for more than 50 years before retiring in 2026. New owners Sandy and Ashlee now run the store. Sandy is a GIA Certified AJP and Diamond Grader and is pursuing her Graduate Gemologist degree, with a particular interest in custom work featuring colored stones. Ashlee began her jewelry career as a child, started as a professional silversmith, and has grown into a master goldsmith; she previously ran her own jewelry line and has years of experience building custom pieces for clients. The shop's custom process moves from a written or photographic concept through a detailed design rendered with CAD technology, then into casting, polishing, and stone setting, with lost wax casting and fabrication offered alongside CAD. The store also carries sapphires, rubies, tourmaline, garnet, and other colored gems in a range of hues.

H Tim Williams Jewelers is at 9640 Mission Gorge Road, in a part of Santee that sits close to Town Center Parkway and Olive Lane, with the Santee Post Office roughly a fifth of a mile away and Cuyamaca Street within a short distance.

The store holds a 4.6 rating based on customer reviews. Years of custom work, master goldsmithing on the bench, and GIA-credentialed gemology at the counter give East San Diego shoppers a full-service jewelry destination in Santee.
