Why this rock is probably not a meteorite:

Maybe it is, but I doubt it. This photo was sent to me by someone who wanted to sell it for $490/gram. He said the "chondrules" were 8mm in size. Some chondrules are that big, but there ought to be some little ones, too. Meteorite chondrules don't have cores, though some have rims. Chondrules don't give the impression of concentric circles like this.
What is it?

Can't tell from the photo.
