Onyx Brooch 800 Silver with small marcasites from 1925

This elegant vintage brooch made of 800 silver features a deep black smooth-cut onyx framed by sparkling marcasites. The handmade unique piece combines nostalgic charm with timeless elegance. A special highlight is the official hallmarking on the pin with the dove wing and the digit 4, which stands for certified silver from 1925 onwards. The brooch features a securely closing pin. Please note that one small marcasite stone is missing, which however does not detract from the overall antique appearance; signs of use appropriate for its age (see photos); Dimensions: approx. 3.5 x 1.7 cm / 4.5g
