Our history

  • Established in 1987, the family here at Johann Paul Jewelers has over 200 years of combined experience in all facets of the jewelry industry.

    From the most seemingly impossible repair, to the delicate complex art of jewelry restoration, we use all the technical equipment available combined with old-world craftsmanship.


  • Our design team at Johann Paul Jewelers has done a fabulous job of procuring many award winning designers to represent our store. Many of these designers have won the coveted Spectrum Award, much like an Academy Award but translated to jewelry. We are also proud to showcase J B Star, a design team that won the "Best in Diamonds" award.

    Of course we must mention our awesome customers who have voted us six times as the "Best Jewelers in Marin" via the Pacific Sun.

  • Judi Stewart

    Judi Stewart

    Originally from New York, I moved to Northern California in the early 1970's and began my sales career doing trunk shows in Navy and Coast Guard exchanges all through out California for a small wholesale company called Rafael Jewelry based in San Rafael.

    From there I worked part time in a few different stores until I became a partner in Paris 1925 where we specialized in platinum diamond estate jewelry from the Art Deco period along with a large collection of both high end vintage and new watches. There is where my true passion for jewelry and selling was born. I took a four year break after Paris 1925 closed to pursue a Psychology degree at Dominican University. I received a call one day from my old friend, Johann, asking me if I would be interested in working at the store part-time. Of course I answered, "Yes!". It is here that I have a loyal client base, where I love designing and selling diamonds.
