Pietra Set of 4 Black Door Knobs #4 by Nicole Valenti

An extraordinary, stone-shaped doorknob to elevate the aesthetic of an empty and sober door in any style decor, this design by Nicole Valenti belongs to the Pietra series of doorknobs inspired by the irregular, textured shapes of natural stones. Minutely handcrafted of etched black bronze, it features a porous convex shape with two bulging elements.
