authentification of what seems to be a jade stone

[0uss]

Hello folks!

I'm a newbie and i found this beautiful stone for sale. I've heard that it's easy to scam non experimented buyers so am willing on your help Hope that the photographs are clear enough to make a judgement. Any advice would be appreciated!

Doesn't look like jade to me looks like the kind of stones buy tumbled in museum gift shops (agate?). But you can't really tell much from a photo.
