    "After I fell and jammed my ring finger, I had to have my beautiful engagement and wedding bands cut off my badly swollen finger.   They were so badly damaged that I thought I would have to have the stones transferred into a new ring.  Janet and Jeff at Deleuse Jewelers proved me wrong and then some!  I am so impressed with how perfectly they repaired my rings and the price was SO reasonable.  To say I am thrilled would be an understatement.  I can't imagine trusting anyone else to repair my fine jewelry." Gail J., San Francisco

    ” Beauty, exquisite design, pleasant and personalized attention. These qualities have been constant in our 20 years of shopping with Janet and Jeff Deleuse – Two exceptionally talented and caring people. The Best!’ Helen P.,Belvedere

    "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

    “Jeff is an incredible gemologist who knows everything there is to know about gem stones. He is a true professional and can be trusted.

    "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

    “Janet and Jeff designed and crafted our wedding rings and did a great job. They worked with existing diamonds we had in an antique ruby cocktail ring, added the sapphire stone and made a beautiful pendant with the ruby. In addition, they designed earrings for our daughters. All are still in great shape today. They are easy to work with and very reliable and trustworthy.” Peg M., San Anselmo
