One of a Kind Jewelry

An authentic voice with an eye for the unusual, Kirsten Muenster’s one-of-a-kind jewelry pieces embody a commitment to the art of storytelling through intricately carved forms of natural beauty and curiosity. These finely crafted pieces are designed to become cherished heirlooms to be collected and passed down.

Enchanting, One-Of-A-Kind Jewelry Designs

One-of-a-kind handmade jewelry is more than adornment; it's a dialogue between the artist, the material, and the wearer, imbued with personal storytelling.

Our Commitment

Environmental commitment and ethical sustainability extend to every aspect of our San Francisco studio. We use 100% Recycled and ethically sourced materials to create our one-of-a-kind jewelry.


KMJ's one-of-a-kind handmade jewelry invites the wearer to express their individuality through a curated collection of wearable art. Layer the Smokey Quartz Collar with the Floral Crowned Phantom Lodolite Necklace, its irregular silhouette echoing the raw, unfinished beauty of nature.

Each piece is individual but works as a collective. Mix, layer, and play, to create a highly personal composition.


Gently clean KMJ’s handmade one-of-a-kind jewelry with a soft cloth to remove any dirt or oils. Store the jewelry in a separate compartment of a lined jewelry box or a soft pouch to prevent scratches. Avoid exposing the piece to harsh chemicals, water, or excessive heat to maintain its beauty and integrity for years to come.

Design Philosophy

"My approach is centered on creative independence and personal expression. A one-of-a-kind piece is personal, rare, and special, it doesn't exist anywhere else in the world."

How often are new one-of-a-kind designs released?

What inspires your one-of-a-kind jewelry?

Design is an intimate conversation with the raw and the refined. I’m captivated by the complex patterns, inclusions, and natural beauty found in rare and unusual materials like fossilized coral, petrified wood, dinosaur bone, lava, pearls, nuts, and shells.

How are one-of-a-kind pieces different from mass-produced jewelry?

A one-of-a-kind jewelry designer's connection to each piece is primal; it’s a part of their imagination made tangible. Pieces are sculpted and transformed through touch. Their hands have shaped the wax, worked the metal, chosen the stones, and knotted each knot. Something new is brought into the world.
