 Fine Jewelry Designer Janet Deleuse began working in the family jewelry business following her marriage to gemologist Jeff Deleuse. She put a degree in molecular biology aside to embrace her true passion for art and design, which she had cultivated since childhood.

By 1982, her love of the hand processes in creating artwork had blossomed into designing magnificent, one-of-a-kind statement jewelry—earrings, bracelets, necklaces, rings—that have been featured in WWD, Town & Country, The Robb Report and Lustre Magazines, among others.

The designer's exclusive hand fabricated pieces are widely recognized for classic lines and fine quality gems, including pearls and flawless WS, VS and EF diamonds set in 18k gold or platinum, as well a penchant for monochromatic styling—"I like clean lines, says Deleuse, even if the design is intricate."

In addition, the designer has recently expanded into couture outerwear and accessories with a collection of pearl evening bags, pearl belts, silk scarves and couture outerwear, all handcrafted in the San Francisco Bay area and offered under the Janet Deleuse label.

Family owned and operated Deleuse Jewelers was established in 1934 by John Deleuse, a master watchmaker and graduate of the Ecole Nationale d'Horologie de Cluses. In 1945, he opened the first family-owned and operated boutique in his hometown of Nice, France.

Janet and Jeff Deleuse opened Deleuse Jewelers in Tiburon, California in 1982, and continue the brand's mission to offer the most uniquely elegant jewelry, using the worlds finest gems and employing the highest quality craftsmanship.

Janet Deleuse is an accepted member of the Contemporary Jewelry Design Group, a national organization dedicated to the promotion of creative jewelry design and committed to the highest standards of integrity and ethics in business and design. She is the owner of Deleuse Jewelers in Fairfax, California.

"I purchased this beautiful chain from Janet Deleuse about 3 weeks ago. It was an online purchase so I was hoping I would be pleased. It exceeded my expectations as it was exactly as pictured. Delicate and perfectly crafted. Packing was very secure and shipping was quick. I would not hesitate to purchase from Deleuse again!"  Michele, New Jersey

"I have used Deleuse Jewelers for many years - for everything from purchasing jewelry to repairing jewelry to getting appraisals on jewelry. Their service and work is superb. I highly recommend them." Suzanne S., Tiburon, CA

"We've always visited this wonderful Jewelers when in Tiburon and last year we were there in perfect time to purchase a beautiful diamond necklace in their sale, just before they moved to Fairfax....I adore my necklace and wear it every day! The knowledge and service is wonderful, nothing is too much trouble for them...." Chrissie, Livermore, CA

"This store has a very pleasant environment and Jeff and Janet are both kind, wonderful people. I used Jeff a few times for appraisals and he was very thorough and was happy to answer lots of questions. He uses scientific methods and tests rather than going solely by appearance as some jewelers will try to do, and his expertise is well respected. On one occasion, he even went out of his way to help expedite a deal for me. He has my highest recommendation.  Suzanne T., San Rafael, CA

 "Janet & Jeff designed our wedding rings 5 years ago and I went back to them for another ring for my wife. Excellent design and excellent quality diamonds and aqua marine. They spent a lot of time working with us on the design, selection of the diamond and aqua marine. Worth every penny!" Shawn S., Tiburon, CA
