Custom Jewelry | How We Work

C5 company specializes in one-of-a-kind, custom jewelry that matches your personality and values, and that you won’t see on anyone else. The process of working with us is exciting and fun. Not only will you love your finished jewelry, but you will have a wonderful, personal story to share with friends and family.

Through our unique collaborative process, you have control and input in seeing your vision come to life.

C5 stands alone in offering a superb customer experience, whether you are local to the Bay Area, or anywhere else. It is paramount to us that the design process is comfortable and relaxed for you. We recognize that the piece we are helping to create will be a treasured heirloom, likely to be passed down for generations to come.

C5 produces any type of jewelry (earrings, rings, bracelets, pendants, etc), with engagement and wedding rings being our most popular. When clients have a specific budget range in mind, C5 tailors the design process accordingly.

After a complimentary consultation, the custom design process starts with an assessment, which serves as a compass for creating the final design. We explain the pros and cons of various metals, discuss design implications and provide information about various gem (including diamond) options. We also do extensive research to source the absolute best diamonds and gems for your jewelry.

C5 meets with you (in person or virtually) as many times as necessary from the start of the project through until you are thrilled with the final piece.

Clients have the opportunity modify or approve the piece at various stages during production. Depending on the process we determine to be the best for creating the jewelry, renderings and/or wax models (computer generated or hand carved) of the custom jewelry may be available prior to casting. Total time from start to finish is highly variable based on the project, but we are committed to meeting even tight deadlines.

Your special piece of C5 jewelry is finished only after we have exceeded your expectations. Our clients rave about their C5 experience. We are confident that you will too!
