As Aaron said, she's definitely not a scrub python- they have distinct head shapes and are usually golden in color and aggressive. That is most likely a mutt carpet- jungle, or coastal or some mix of them. It's definitely not a diamond at all. I wouldn't think there's even any diamond blood in it, but a low % of diamond, such as if it was a 75% jungle/25% diamond, would not look much like a diamond. At any rate, for $120, you definitely didn't pay too much. So enjoy your new carpet buddy- no matter how colorful or dull looking, they are awesome snakes with tons of personality. She looks a lot like my big mutt, Voodoo. He's a sweet big boy and one of my favorites.
