Vintage Trifari Mother of Pearl Inlay Trifoil Earrings

This pair of vintage clip-on earrings features a sophisticated trifoil or stylized floral motif, likely dating from the mid-20th century (circa 1950s-1960s). Each earring is constructed with three marquise-shaped leaves or petals arranged around a central point. The petals are inlaid with iridescent white mother of pearl, showcasing a natural luster with subtle pink and green undertones. The metalwork is a gold-tone finish, possibly a proprietary alloy like Trifanium if they are indeed Trifari, which was common for the era. The outer edges of the petals feature a textured, ribbed, or rope-style milgrain detailing that adds depth and contrast to the smooth polished surfaces. The design follows a classic mid-century modern aesthetic, balancing organic shapes with structured symmetry. Regarding condition, there is visible tarnishing and oxidation on the metal surfaces, particularly in the recessed areas between the petals and on the clip mechanisms. The mother of pearl insets appear intact without significant cracking, though surface grime is present. No specific maker's mark is visible from the front view, but the craftsmanship is consistent with high-quality costume jewelry manufacturers of the period. The clip-on backing suggests an era before pierced ears became the standard for fashion jewelry.
