Onyx and Mother of Pearl Brooch

A sterling silver brooch set with marcasite, black onyx and mother of pearl in a sharply balanced geometric design. The piece is composed around a long horizontal bar, with contrasting domed sections creating a clean, architectural silhouette. The black onyx brings depth and weight to the upper half, while the mother of pearl below gives the composition a softer, luminous counterpoint. A line of marcasites runs through the centre, adding texture and definition while reinforcing the brooch’s strong linear profile. It is a compact statement piece with a clear Deco sensibility. The contrast of dark and light surfaces gives it immediate visual impact, while the restrained form keeps it precise, graphic and easy to wear now.
