This 2 1/2" oak leaf pin is created from a real leaf and cast in sterling silver. It comes in two variations: polished sterling with leaf veins oxidized to highlight detail, and accented with 24-karat gold foil fused to the surface in a process called "keum boo", and the remaining sterling surface oxidized for contrast. Both styles feature a "scatter pin" type back, making them simple to pin to clothing or lapel.
