Large rock looks like amber but isn't

[Hugosmom]

Can anyone tell me what this rock could be? I found it at a thrift shop so I don't have any location help.
Thanks!

Carnelian. A species of agate.

Past time for more coffee.

Thank you! So this one has been polished some, then?

I doubt it. Looks river worn. I used to pick up similar rocks from the middle fork of the Willamette. Many had a similar appearance.

Or chalcedony. Our agates here are chalcedony and some look like that though generally not that large but beach tumbling will polish like that too
