Btw the circles are circles bc the rounded shape. The colors in rainbow obsidian is layered, so if you want to see multiple rings of color you just round the surface as you're cutting it. If you get a totally flat piece you won't see those color changes, just the layers when you look at it from the side.
I got a rainbow obsidian freeform about a month ago, a d already got a second one bc I'm OBSESSED 😍
