The first is an 18th-19th century pair of gold and white jade 'double happiness' examples, the second a gold and jadeite examples, the gold earrings possibly from the Ming dynasty, the green jadeite bi-form pendant from the late Qing dynasty; and a 20th-century pair of gold mounted green jadeite 'teardrop' examples.
Note:
A similar example to the second pair, see LI, Ya. Erpan Liuguang, Zhongguo Lidai Erhuan. Beijing: Zhongguo Fangzhipin Chubanshe, 2015, p 187, chart 10-4, no.5. Li also discusses the combination of Ming and Qing elements during the late Qing dynasty.
