Is This A Petrified Tree Stump?

My parents have always told me this is a petrified tree stump. They've had it for as long as I can remember. It has sat outside in the weather for more than for 25 years, that I know of. It is as heavy and hard as solid stone and despite its weathered look, it is not crumbly or flaky.
