We create bold designs for the discerning eye.

KÁLAMO is a jewelry house founded by Antonio Cruz Soto and Diana López Sepúlveda. In Madrid, we design and produce collections with a distinct identity, where creativity, discernment, and ongoing research into materials, techniques, and finishes come together. Our academic background and continued commitment to learning shape a way of working focused on refining the design, proportions, and execution of every piece. Each collection is guided by a clear vision: to create jewelry with presence, character, and a language of its own. Our surroundings, on the outskirts of Madrid, are part of that sensibility and of the way we conceive each piece.

Combining contrasting materials with balance

Our collections explore textures, colors, and contrasts inspired by nature. We prioritize natural materials—such as semi-precious stones, leather, mother-of-pearl, wood, and pearls—and incorporate more innovative ones when the language of a piece calls for it.

Our Responsibility

Conscious production

We work exclusively with trusted suppliers and select ethically sourced materials. Each piece is handmade in our workshop, with rigorous attention to process, finishes, and respect for the people involved in making it.

Pieces designed to last

We create jewelry meant to be worn, enjoyed, and kept for years. That is why we offer our Lifetime Repair Service, with complimentary repairs during the first two years and continued care for the life of each piece.
