The Windsor Plate came into its current form from the neo-classical architecture made famous by Thomas Jefferson's Monticello and the royal Windsor estates in England. Pair this with the Biarritz Knob, with its distinguished shape and effortless shimmer, this exceptional oval crystal knob adds a statement to any door. All Grandeur crystal knobs are created from lead-free crystal for unparalleled clarity and beauty, and mounted on a solid (not plated) forged brass base.
