Hopefully not. The base seems stable just from the looks of things. I can’t wait until the final pic with maybe it back lit or something. Will you wax, buff, polish, or oil it to bring more contrast of color out?

Basically just sanding to a very high grit. It will shine on its own at that point. And then it will get powder coated with a clear UV-resistant finish. The color of this stone will fade over time when exposed to UV light.
Calcite is beautiful in all of its tints/shades. It has such an ethereal patina.
