These elegant earrings feature 90-year-old jade buttons from the time of the rule of Puyi, China's ''last emperor.'' Bezel-set in 22-karat gold vermeil, they feature dangling tiers of cultured freshwater pearls. Wear an evocative piece of history that symbolizes the end of an era from nearly one century ago. As these are handmade by artisans using vintage buttons, each will vary. 2''L.
