Found this cool rock at lake Tahoe. It has 2 white rings around it that are so perfect I thought at first they were drawn. Now it lives in my Chia pet garden. Here's an additional pic.

Thanks so much for the additional pictures! It definitely looks like crystal in the banding to me. It's hard to tell, but if that is flourescent, it's the right color for feldspar. I hope you're able to ID it!
I love pieces like these. In my area we have flourescent sodalite that's commonly referred to as yooperlite. I have two in my collection, and they are some of my favorite stones. They come in all kinds of crazy patterns, and most of them just look like boring, grey rocks when you see them under normal light. Under UV they look like a whole new piece. Here's an example: Side By Side Yooperlite
Wow that's really cool! Thanks!
