Vintage Marcasite and Faux Pearl Brooch

This item is a small, ornate brooch or pin with a floral-inspired design. It appears to be constructed from a base metal, possibly brass or a similar alloy, with a matte gold-tone finish or patina. The brooch is roughly 1.5 to 2 inches in length and features a central design resembling a flower with four petals and a prominent faux pearl in the center. The surface of the petals and surrounding elements are densely encrusted with small, faceted stones that appear to be marcasites, set in a pave style. While the user mentions "diamonds," these are likely marcasites due to the overall aesthetic and historical context of similar jewelry pieces. One side of the brooch extends outward in a decorative, scrolling flourish also accented with marcasites. The reverse side is not visible, but it would typically feature a pin and clasp mechanism for attachment to clothing. There is a visible patina on the metal, suggesting age, and some potential wear on the elevated surfaces of the design. The craftsmanship exhibits detailed metalwork in the settings for the stones and the shaping of the floral and scrolling elements. The style suggests a vintage period, possibly Art Deco or a later revival, characterized by the use of marcasites and the stylized floral form.
