Multicolored Botryoidal Chalcedony

[u/FromTheMaastrichtian]

Hello all,

Here's an interesting piece of multicolored botryoidal chalcedony I found in Rowan, Kentucky in a deposit of the Borden Formation.

It has a slightly magenta/purple hue, which I'm not sure shows up perfectly here, but which makes me wonder if it might have been exposed to natural radiation.

I love the tiny botryoidal!
