Pearly Pale Blue Lace Agate Cabochon Sterling Silver Chandelier Earrings
They are not marked but I am pretty sure that they test out as sterling sliver.
The agate is blueish white with striations. I suspect that it is a pale blue lace agate but I can't say for sure.
The wire hooks lock into a triangle hinge so that they will be secure.
They measure almost 2 ½:” long including the dangles x ¾ “ wide.
