Jeff Deleuse, Graduate Gemologist and Certified Appraiser

Janet, thank-you for everything you do. As I said before, you are truly an artist, and that is why it is so special buying jewelry from you.” Peter, Atlanta, GA

"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

“Jeff is an incredible gemologist who knows everything there is to know about gem stones. He is a true professional and can be trusted. The quality of their work is impeccible and always consistent. I would recommend Deleuse Jewelers to anyone looking for a new, “bauble,” for themselves or someone special!” Terri B., Ross

“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

” 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

“My husband and I have been customers of Deleuse Jewelers for more than 10 years and we have purchased many beautiful and personalized designs. Janet’s and Jeff’s creations are exceptional.” Diana S., Tiburon, CA

Found what I was looking for and more. An organic skin care line with no preservatives, which resulted in truly moisturizing my skin without any feeling of dryness. More than a good product! Constance, Marin County

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

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. Belvedere, Ca

SO few places that take care of their customers like this anymore!! I have had them do MANY repairs and quite a few "tweaks" on family jewels. They took my Grandma's engagement ring and redesigned it to a gorgeous cocktail ring!! A PLUS - all the way!! Mary M., Tiburon, Ca
