Mid-century brooch is a bright green swirl of waving lines, a beautiful square of kelly and hunter hued waves and swirls in malachite. The scalloped, mid-century era brooch frame of sterling silver (acid tested) echoes the waving motif of the stone. The rolling waves of malachite give the pin a feeling of movement. The pin is in excellent vintage condition. This lovely pin/brooch will make a colorful addition to any jewelry collection. The brooch measures approximately 1 3/8 inches by 1 inch.
