Ulexite

A polished slab of the mineral Ulexite a borate mineral, NaCaB5O6(ΟH)6·5H2O, that consists of hydrated sodium and calcium borate. It has fiber optics qualities, hence the pastel colors coming through from the color underneath this specimen. The surface is actually flat and smooth. The textures are a result of crystal structures inside the stone creating "cracks, waves, and mountains".
