A rare and exceptional sterling and moonstone ring signed Macefield. William Mason and Leonard Field were a collaborative effort of artist/jewelers from Winchester, MA. ( the North Shore ) who were most active in the late 40's and 50's. This ring is a size 6-6 1/2 and the moonstone sits high in the sterling setting. The ring is in fine original condition with no chips or cracks to the stone. Magnificent craftsmanship in a sleek Modernist design.
