Que Sera Stone (Also know as Llanite, a form of Rhyolite)

Rhyolite is an extrusive igneous rock, formed from magma rich in silica that is extruded from a volcanic vent to cool quickly on the surface rather than slowly in the subsurface. It is generally light in colour due to its low content of mafic minerals, and it is typically very fine-grained (aphanitic) or glassy.
