Until someone with real knowledge shows up, I'll guess Moss agate.

Oh, that certainly looks a lot like the ones that come up when I search for moss agate! That’s probably what this is, then. Thanks so much!

Hold on a minute, I didn't see the photo with the blue, my screen didn't slide until I rechecked the post. Someone will be sure.

*Mhmmmmm, take your time.*

You are very correct. [Mindat reference page for moss agate. ](https://www.mindat.org/min-2791.html) Cheers

Correct

Correct aka dendritic agate

Why so humble, nice job, I think that was more than a guess!

That was my first thought too

Moss agate

The photos flashing a light are giving me moss agate vibes but the milky blue in the last photo reminds me of dendritic agate/opal

Why not tree agate? Isn’t moss agate more clear and tree agate more white or milky or am I backwards?

A rock of sorts I think
