I got more info on the jewelry. My grandfather's grandmother had the same Celtic design earring with back, in the 1920's/1930's. The black stone earring is from the Art Nouveau time (1880-1914). The necklace is from the Victorian era. P.S. If you are wondering why I only showed one earring of each type, is because it was easier to get more close up photos that way, not that I only have one of each earring.
