Effy Earrings, Pendent Sterling Silver Chain w. Simulated Sapphires

Sweet consisting of prong set Earrings Chain and Pendent, earrings are post for pierced ears. I can only see the 925 mark for Sterling Silver on the oval tag , see photo, next to the lobster claw clasp on the chain but nowhere else. New in original packaging, necklace has Lobster claw closure and is 18” long. I do not think the stones are real Sapphires but they have beautiful Ceylon Sapphire color and I cannot guess the carat weight but see the penny on the photo for comparison. Comes in original packaging and never used.
