Our founder | she/her

Kate Ellen, Goldsmith

Raised in the Redwood forests of the Bay Area, founder Kate Ellen grew up playing in creeks and roaming feral in the woods. Today she is the intuitive leader of the Crown Nine team and sole-designer of both our Vow Collection and our label of fine jewelry.

Her education is in public health - she brings her unique background and experience to every level of the company, poising communal good at the heart of everything we do. She lives in Sonoma County with her two young children, husband, and dog Jim.

Our studio

We design and craft all our designs in our studio, using an array of ancient and modern techniques and tools to ensure the highest integrity of each design. Our studio is home to our beloved vintage hand-tool collection and jewelry benches where we fabricate, wax-carve, mold, solder, saw, and expertly construct our Vow Collection and our label of fine jewelry.

Our boutique

The showroom is about connection- to each other, to expression, meaning, art, and beauty. Designed to be welcoming and relaxing- a place where people can come to explore and just enjoy a moment of peace. The boutique is open for in-person visits by appointment only.
