Pair of Adamant Door Handles
The Adamant door handle, designed by Patricia Urquiola, combines architectural design with functionality. Its faceted geometry, inspired by the purity of crystal, plays with light to create a contemporary, sculptural look. Its wide, ergonomic lever ensures a comfortable grip, while the quality of the solid brass and the finishes highlight its elegance and durability. Adamant perfectly exemplifies the balance between refined aesthetics and intuitive use that is characteristic of Urquiola’s style.
This pair of door handles is intended for:
- on newer doors (mortise locks);
- for doors between 38 mm and 40 mm thick (standard thickness). This handle comes with a 7 mm square spindle and the adapters needed for installation.

Description
Adamant – The Door Handle in All Its Forms
The Adamant door handle, designed by Patricia Urquiola in 2009, is a bold interpretation of architectural design applied to an everyday object. True to the designer’s style—which balances formal rigor with intuitive sensitivity—Adamant stands out for its chiseled, almost mineral-like geometry, evoking the purity of a crystal or the complexity of a sculpted surface. Its faceted shape defines the space with precision, creating subtle plays of light depending on the viewing angle and the chosen finish. Every edge and every angle is designed to transform the handle into a form that is at once clear, assertive, and deeply contemporary.
But beyond its visual richness, Adamant embodies a genuine reflection on usability. Its deliberately wide, almost generous lever ensures an intuitive and comfortable grip, contrasting with the apparent sharpness of its geometry. The motion is fluid and natural, while the feel reveals a dense, stable surface, enhanced by the quality of the solid brass and the high-precision finishes, notably in polished or satin chrome. This attention to both ergonomics and materiality reflects Urquiola’s holistic approach, in which technique never takes a back seat to aesthetics—or vice versa.
Adamant does not seek to blend into the background: it defines the space with both authority and delicacy, like a signature. It fits perfectly into demanding contemporary projects—whether residential or commercial—where every detail counts. In short, Adamant is not just a doorknob: it is a design statement, a bold object that pushes the boundaries of functionality to enter the realm of architectural expression.
