Tis it in the air, thinking the inside is some sort of quartz, but honestly kinda a scrub about this

Looks like a slice of a petrified wood limb. Sometimes in fossilization certain agates fill in where the normal minerals would, maybe that bit of trunk had a huge sap deposit? but sides do look like tree bark.

Slice of petrified branch.
It fossilized upside down relative to your pictures.
The bottom (top in your picture) rotter away somewhat before becoming encased.
Mineralization progressed from the bottom and top, water seepage filtering down and pooling. The outer shell mineralized, then the remaining wood rotted completely away except for the heartwood, which rested on the bottom in the now open (though water filled) void and mineralized there.
After that point the remaining void filled with crystal growth like any geode, which gradually filled up entirely.

appears to be a plain old geode.

it could be wood, but there's no way to tell from that angle.

post a side shot.

It's agate not petrified wood.

it's /diy/ territory, but you could take that, tape LEDs to the back of it, and sell it to hipsters ez.
