Sterling silver, genuine pearl and gemstone pierced earrings. I am not sure of the gemstones. Can be citrine or quartz perhaps. the pearls are genuine. Marked 925 (sterling silver) and "NF" on the back top. Which stands for manufacturer Chapal Zenray.
They measure 1 1/2" and the bottom portion is 1/2" across. Great shape! They will come with disc backs. Circa 1990's - 2016
