Irregular marble cabinet knobs with brass decorative stems bring together natural beauty and refined craftsmanship. Unlike traditional knobs with uniform shapes, these pieces celebrate the unique variations found in marble. Each knob is truly one of a kind, highlighting distinctive patterns, veining, and color variations within the stone. This individuality ensures that no two knobs are ever the same, adding authenticity, character, and a touch of artistry to your space.

Beautiful hardware with a heavy weight not flimsy makes my black entry door sideboard POP. Blondell. Philadelphia, PA. Sun May 10 2026

The lunar eclipse knob adds intrigue to any chest, cabinet, or desk. Each piece is CNC machined brass. Our signature hand-polished luster brass finish has a soft gentle glow.

Showcasing the look of Italian marble cradled on an asymmetrical base, the elegant natural material adds modern flair to classic glamour.

Whether replacing the hardware on existing cabinets or installing new cabinets, the variety within Sietto’s adjustable collection’s base finishes and glass colors provide the flexibility you want. We highly recommend ordering a single item as a sample to test against your actual cabinetry. 

Completely unexpected. I thought for sure. The clear piece is going to be acrylic and much to my pleasant surprise it’s glass! This one’s definitely a candidate for our other cabinets.. Luis Antonio. Bainbridge Island, WA. Fri Dec 26 2025

Hawaiian Lava Stone Knob has a rich contrast of reddish-orange on a white crystal that looks like oozing lava. Use as a dresser knob, cabinet knob, bathroom knob, desk knob--the possibilities are endless!
