Davvero bellissima!
Ha anche diverse irregolarità sul carapace...
Qualche ipotesi sul tipo di mutazione?
L'occhio sembra scuro quindi escluderei un semplice amelanismo.
Qualche notizi in merito sulla fonte della foto?
You was very near to right answer, Sir! It is type of deep amelanistic color Mutation, called "SILVER" by genetic specialist. The silver color is appearing in simple colored very dark (near to black) animals, where absence of melanin is making one splendid grey color (grigio, as Danilo wrote in the begining, and it should be right name for this color)...
So, it is deep amelanistic appearance, called silver (argento), and it is appearing frequently in all dark colored (dark blue, black, dark grey) animals, like in Black Swan, black cattle, etc..., etc...
