It's hard to tell from a photo, but this looks emobossed to me. If real, you might see some scale edges lifting a bit, and there seems to be too much "space" between the scales on your close-up. And, from what I can tell the pattern looks too symmetrical to be genuine snakeskin. Honestly, though, feeling the bag is usually the only & best way I've found to tell for sure on snakeskin. Run your hands both ways across the surface; you usually can feel a grain or at least some roughness. Embossed will feel smooth (except for the bumps of course).
It is a very lovely bag, though, genuine skin or not!
