Marshall Field & Co. 'Craft Shop' Silver Brooch or Jewelry Component

This item is a piece of handcrafted metalware, likely sterling silver, featuring a definitive hallmark from the famed Chicago retailer Marshall Field & Co. The reverse side of the object displays an applied rectangular plaque with the stamped inscription: 'MADE IN OUR CRAFT SHOP MARSHALL FIELD & CO.' along with a distinctive stylized 'G' and 'C' logo. This specific mark identifies the piece as part of the Arts and Crafts movement production from Marshall Field's internal jewelry shop, which operated approximately between 1904 and 1950. The object exhibits a hand-wrought, irregular form with soft, rounded edges characteristic of the Arts and Crafts aesthetic. The metal surface shows a significant aged patina with darkening in recessed areas and light Surface scratches consistent with age and use. The craftsmanship is high-quality, showing evidence of hammer marks and hand-finishing rather than mass production. Although the full front design is not visible, the construction suggests it is either a brooch, a large buckle, or a pendant component. The metal appears dense and has the luster typical of high-purity silver. There are no immediate signs of major structural repair, though significant oxidation is present, which is often preferred by collectors of period Arts and Crafts metalwork.
