A small, women owned team
Founded by designer Brooke Miller in 2010, Porter Gulch is an independent fine jewelry studio in Sausalito, California. Our small team creates one-of-a-kind jewelry centered around exceptional gemstones, from our ready-to-wear collection to custom pieces designed in collaboration with our clients. Everything we make is designed to feel personal and be worn for a lifetime.
Jewelry becomes part of our identity and tells the story of who we are. I feel honored to help my clients create jewelry that represents the milestones and celebrations that matter most.
Future heirlooms for everyday life
Our designs always begin with the gemstone. We let each stone’s color, shape and character lead the way, adding details that complement rather than compete with what makes it special. We’re drawn to designs that feel interesting but never trendy—pieces with enough personality to feel distinctive today, yet timeless enough to love decades from now. And when a gemstone has something wonderfully unexpected about it, we celebrate it.
Meaningful moments into lasting memories
Jewelry has a way of becoming part of our lives. A ring worn every day, a necklace given to mark an important moment, a piece that’s eventually passed down—over time, the jewelry we wear carries the memories and stories that make it ours.

Brooke
Founder & designer
I’m the founder and designer behind Porter Gulch. I design each of our collections and love searching for truly incredible gemstones—stones with unusual color, beautiful shapes or simply exceptional brilliance.
I’m endlessly fascinated by the fact that these gems took millions of years to form in the earth, and now we have the honor of turning them into something you can wear to celebrate the special moments in your life.
I’ve built Porter Gulch around the things that matter most to me: exceptional gemstones sourced through people we trust, thoughtful design, quality craftsmanship and a personal experience from our small team. After more than 15 years, I still feel incredibly lucky to make jewelry that becomes part of our clients’ lives.

Amy
Gem specialist & client sales
Jewelry has fascinated me for as long as I can remember. I love discovering pieces from different eras, collecting unique and vintage jewelry, and learning what makes a gemstone truly special. That lifelong interest eventually led me to study at GIA and deepen my knowledge of gemstones and diamond grading.
One of my favorite parts of working at Porter Gulch is helping clients discover what they love. Whether I’m searching for the perfect gemstone or exploring design ideas together, I love being part of the process and helping turn something they’ve imagined into a piece they’ll treasure for years to come.

Cam
Creative & marketing
I’ve always loved jewelry with character—pieces that feel a little different and gemstones with colors you don’t see every day. Earth-toned sapphires are a particular favorite. I spent several years designing and making jewelry myself, carving pieces in wax that were then cast in brass. That experience gave me an appreciation for the craft and all the small decisions that go into creating a finished piece.
Today, I get to tell the Porter Gulch story through creative direction, photography, styling and marketing. I love finding interesting ways to photograph our jewelry, dreaming up the world around each new collection and creating imagery that feels as special as the pieces themselves.

Susmitha
Client & production coordinator
I’ve always been drawn to jewelry, growing up around gold and diamond pieces that held both beauty and meaning. While studying at California College of the Arts, I began taking jewelry-making classes and loved getting to understand the craftsmanship and care behind something I had appreciated for so long.
At Porter Gulch, I get to be part of a piece’s journey from the first client conversation through production and all the way to the finished jewelry. I especially love working directly with clients, learning what they’re looking for and helping guide them through the process of creating something that feels personal to them.
