Sigi Pineda was a master Mexican silversmith renowned for his bold, modernist designs and high-quality sterling craftsmanship. Active primarily from the 1950s through the 1970s in Taxco, Mexico, Pineda blended pre-Columbian influences with mid-century modern aesthetics to create distinctive jewelry and decorative pieces. His sterling silver marks typically include “Sigi” in stylized script, “Hecho en Mexico,” “Sterling,” and a design number, often accompanied by the Taxco registration code (usually “TP” followed by numbers). Each piece reflects Pineda’s commitment to handcraftsmanship, with clean lines, sculptural forms, and refined detail. Collectors highly value his work for its artistry, cultural relevance, and limited production. Recognizing Sigi Pineda silver marks is essential for confirming authenticity and evaluating a piece’s origin, style, and potential worth. Whether it’s a bold cuff bracelet or a sculptural brooch, Sigi Pineda sterling represents the height of 20th-century Mexican silver design.
