Vintage Gold-Tone and Nephrite Jade Cufflink

This is a single vintage cufflink featuring a classic mid-century rectangular silhouette. The piece is constructed with a flat gold-tone metal base plate, onto which a cylindrical rod of mottled green nephrite jade is mounted. The jade displays a characteristic leafy green hue with darker inclusions and a semi-translucent quality typical of natural stone. The stone is secured to the metal backing with two small, circular gold-tone rivets or prongs visible on the front face. The metal backing is extensively scratched and scuffed, indicating significant wear and use over time; the gold plating appears thin or worn, particularly on the edges. On the toggle arm, there is a visible maker's mark or hallmark consisting of the letters 'AP' followed by a registered trademark symbol, which suggests an American manufacture likely dating from the 1960s or 1970s. The construction is sturdy but utilitarian, reflecting a mass-produced fine-finish accessory of its era. Overall condition is fair to good, with the jade remaining intact while the metal components show heavy superficial patina and micro-abrasions.
