VINTAGE TURQUOISE IN 925 SS, GUC, Clip on Earrings, 1" x .75" Hallmarked J#2502

I dont know exactly how old these are, but are hallmarked 925 made in Thailand. Clip Back dirt of dates the earrings. I am sure the Turquoise is authentic but have not been tested. As a rule, older earrings with clip back mounted in Sterling have authentic stones.
