Possible American Indian hand tool?

[velodromed]

Hello, I posted about this rock in the intro thread, but in case those are not viewed as often I figured I’d post here as well.
My 10 year old and I found what looks like an Indian hand tool, but it’s not one of the softer rocks I’m used to seeing them made from, like limestone. Normally we’d have begun tumbling or cut the rock right away, but before doing so I want to make sure it’s just a rock and not an artifact. Thanks and much appreciated!

Welcome to TreasureNet...Sorry, from pictures posted it is natural, no signs of being worked or used by native Americans.

Thank you very much! This is good news for us because we really want to tumble and polish it.

Looks like what I call gum rock because most pieces look like a chewed piece of gum, I’m thinking natural too, and I suspect it’s some kind of jasper.

Nice, my 10 year old and wife will crack up when I tell them that. Yup, when I’ve cut/polished similar rocks like this before, some are a full mix of the quartz family while others are chert covered chalcedony nodules. I think I’ll tumble it whole and see what happens. Thanks man!

I throw most in my fish tank for gravel but here’s a few I have laying around seems to be the same stuff.

Nice, I see what you mean by chewed gum look. I’ll post the results of mine when it’s done tumbling in a couple months. I won’t tumble this one smooth, I just want to see what’s underneath the chert and Jasper outside. I think the knobs will be clearish chalcedony from similar ones I’ve broken before. I have 80-1000 grit Dremel buffing balls that may work for polishing the ‘cup’ area. It’ll be the heaviest shot glass we have 😅
