Our Expertise

Since 1952, Koser Jewelers has been proud of our family traditions of providing quality merchandise at competitive prices and personal service to our community. Randy  Wolgemuth took over Koser in 1988, and has been carrying the tradition of excellence, while embracing the new technological advances.

Our staff is made up of GIA Graduate Gemologists, JA Certified Bench Jewelers, and award- winning designers. And, as the only Master IJO Jeweler in Lancaster County, you can count on Koser Jewelers to provide a quality selection, create a custom piece, or to repair a piece you love.

With a full-service, onsite repair and design shop, our jewelry is made and repaired in-house. And, if your diamond needs reset or your engagement ring needs sized, we can do it in front of you, while you wait.

Our team of highly skilled and caring professionals can accommodate every request - big or small, simple or complex and we provide the same level of care, expertise and courtesy to all.
