About J Briggs & Co

Meet Jennifer, Designer and Certified Gemologist

Jennifer Briggs Jenkins was drawn to jewelry as soon as she was old enough to string beads ~ and know enough not to eat them. When she was six, her father brought home her first set of jeweler’s hand tools and her passion was born. Jen’s mission is to create beautiful, versatile, fine jewelry that can be shared and enjoyed for many years to come.

She founded J. Briggs & Company in 1997 with a total devotion to her clients. The majority of her designs are based on each client’s specific needs and desires, with the result being something extraordinary to pass down from generation to generation. “The interaction I get to have with my client designing their jewelry is a very important part of the process. When someone entrusts me to create his or her special piece, I take that responsibility very seriously. I am emotionally vested and do my best to make sure the design experience compliments the exceptional jewelry that we create..”.

The jewelry on the J Briggs & Co website represent a mix of her favorite original designs for clients ~ as well as her newest collections that combine exceptional gems, versatility and timeless design. J. Briggs & Co is striving to offer something for those who wish to commemorate a special milestone or a celebration in life.

Jen opened her studio in Northborough, Massachusetts in 2011. It is her place to create, design and meet with clients. It is her childhood dream turned real. When asked, she described her studio as her “haven”. You can find her there regularly, whether she’s meticulously finding the right gem, sketching, creating new designs on CAD (computer aided design) software or visiting with clients, she will always have an enormous smile on her face. She is doing something she loves to do and it shows. In November of 2021, Jennifer opened her 2nd location in Jaffrey, NH in a beautiful old mill building in the center of town. New Hampshire is a Sales Tax Free state!

Whether you are local or far away, Jen looks forward to serving your jewelry needs with the care and attention to detail that have become her trademark.

J Briggs & Co donates annually to several local causes and charities. Jennifer is passionate about education and health and is a dedicated supporter of the Shrewsbury & Northborough Public School Systems. Philanthropy is an important part of her life.

We are proud to be an LGBT friendly business.
