Vintage Circular Patinated Brass Button Earrings

A pair of circular, domed clip-on or post earrings measuring approximately 1 inch in diameter. The earrings are constructed from a brass base metal and feature a decorative surface treatment achieved through an advanced heat or chemical patination process. The coloration is divided into two distinct zones: a lower section of dusty rose/mauve and an upper section showcasing a gradient of seafoam green and cerulean blue. The blue-green areas exhibit a 'cell' or bubble-like texture, characteristic of salt or chemical-induced patina reactions often found in boutique 1980s jewelry design. The items show a smooth, matte to semi-gloss finish. The craftsmanship suggests an artisan production, likely from the Mid-Century Modern revival period or the late 20th century (circa 1985-1995). The condition appears good with minor age-appropriate surface oxidation and light wear to the edges. No visible maker's marks are present on the front face, though the construction indicates a solid metal backing. Each piece is unique due to the volatile nature of the patination process, making them a one-of-a-kind example of studio jewelry.
