Pretty Necklace

Pretty necklace with delicate gold chain and smoky topaz-like stone. I can’t confirm that the stone or gold are real. The setting on the stone has some discoloration that indicates maybe it’s plated. The chain might be real. The stone is pretty and feels real, but I don’t have confirmation of that. Chock it up to a pretty costume necklace. Please review the pics and feel free to ask questions.
