Sliver tone turquoise like ring size 5.75

pre-owned in good condition (like new) sliver tone turquoise like ring it's beautiful. I'm not sure if it is real turquoise? because of not sure. so selling it just like a fashion ring price . it's a very good look . the ring color is not that deep blue . my camera take pictures made it more blue .. but it's not that blue like in pictures.
