Huge agate or just a cool rock?

Can anyone provide any insight? My grandpa has had it for years in his garden.... Thanks for the help. It weighs 16lb

It looks to me like an agate. The characteristics are a little different, but I believe it is... Get it checked at a shop. Either way its a really cool find!!! Way to go!!!

Ive seen what was told to me to be petrified wood that was very similar.

Same here. My dad had a peice of rock like that in our back yard. I was told it was petrified wood. I am no expert though. Still cool though.

The fractures in it remind me of chert or flint .

Petrified or not, way cool either way!

Everything that was pointed out to me as petrified wood didn't have any sort of glossy surface to it. The petrified wood I've seen was always had a dull flat surface. Similar colors but not shinny at all.

I'm probably the last person to ask but I'd lean away from petrified wood.

I believe its petrified wood. My great grandpa had quite the collection in his front yard down in AZ. Those colors are fantastic though! Quite the cool rock!

Very cool petrified wood.

Nice piece. It's called agatized wood.
