Sterling silver omega necklace with 9 sparkly zirconia stones

Used condition Length of the necklace is 16" No 925 stamp, but the necklace is made out of real sterling silver (tested at a jewellerly store) The stones move in their setting, but that's the design The stone in the middle is chipped on one side, but it's only visible under a super close inspection, no way to even notice it when the necklace is worn They arwn't firmly set, they move a bit The stones are super sparkly!
