A quiet swirl of early 20th-century craftsmanship.
This antique brooch is stamped PSCO, attributed to Plainville Stock Company, an early American jewelry maker known for gold-filled designs.
The piece features layered, intertwined gold-filled loops centered with a small natural opal cabochon. The back retains its original early C-clasp closure — a hallmark of pre-1950 construction.
The warm patina and gentle surface wear speak to its age and authenticity.
