How Well Will it Tumble? - Mystery Rock from Deming NM

I picked up this rock near Deming New Mexico on a very hot day. Perhaps I was a little delirious from the heat because I’m not sure what I saw in it but we still must find out how well it tumbles and polishes!

Quartzite with mixed minerals? I like it!

That sounds very likely 🤷‍♂️

It looks like a moss agate imposter!

I can see that 🤔.
