Featuring a spherical form and honed finish, the Black Marble Hubble Knob offers a contemporary shape cut from organic material. These luxurious knobs serve as a bold upgrade for cabinetry and furniture. Each has subtle variations in color and veining, making every knob unique from the next. If you would like to request specific marble coloring, please purchase our Hand Selection Service.  Use care during installation and hand-tighten all screws. When installed, the screws should feel firm, but not extremely tight. Using power tools or over-tightening the screws may crack the marble.
