I Want To Double Check My Geology. Found A Beautiful Swirled Rock At The Store

It was near the fish section at the local pet store. Now that I’m thinking about it, it may be sandstone.

It’s white and red with beautiful swirls and a circular pattern in it. Does the sound like sandstone to anyone else? It’s a bummer because it would’ve looked great in the tank. I’ll work on getting pictures up.

You are describing "Rhyolite". Its an aquarium safe igneous volcanic rock. Fish stores sell it as Rainbow Rock.

Does it resemble this? Wonderstone

I've seen it at PetSmart, Petco, and online. Seems to be safe, and does look good
