sparkly stud earrings stamped 925 china on the back

sparkly stud earrings stamped 925 china on the back . Has this cage like setting that allows lots of light around the pretty stone to make sparkle . A dime and ruler are in pics to help with size visualization. My kitchen scale says 5 grams see pic# 7. Questions are always welcome . One post has a slight bend in it see last 2 pictures ..I lent these out to a friend and they came back that way . Very pretty they have a very brilliant sparkle reminiscent of the stars on a moonless night In my opinion.
