Riverstone is technically speaking a “phyllite” slate formed within a precambrian rock sequence between 560-640 million years old.
Phyllite marks a culmination – it is what happens when the geological forces that form slate are permitted to continue. With each step – from sediment to shale, shale to slate and slate to phyllite slate – the stone becomes harder, denser and stronger.
This extra length of time in the ground has evolved the original slate structure in such a way that that its technical credentials – in particular water absorption and durability – are second to none.
Moreover, the prolonged heat and pressure exposure as well as sustained metamorphosis has allowed it to develop a distinct phyllitic sheen (the mica content on the surface in particular is quite pronounced), which is a key differentiating feature of the stone.
