This circular door knob knob is a ball shape - so satisfying in the hand - in a mosaic of mother-of-pearl in all its subtle shimmering variations of colour from clotted cream through to palest ivory, with a brushed nickel stem. You won't find any of our range of hardware anywhere else as we design our own collection. What we design and make is exactly what I would like in my own home and in some cases exactly what I have there. We use a range of different materials, rough cast metal, thick glossy enamel, brass, palmwood, resin, birch, ceramic and brass, but whatever the material, I always keep it simple and sophisticated.
