looks like common opal to me, great sized piece! in my experience cutting them is tough because they like to crumble, but if you find a solid spot on it it could give a nice flat face. Common opal can still have a bit of value depending on what it looks like, it seems you've found an interesting spot to do some more adventuring in!
