Petra

PetraPetraSlate was started out of the growing need in Colorado for quality slate products. In the early 90’s slate was considered an “exotic” stone in Colorado, even though it had been used for hundreds of years in Europe and the Northeast US. This was the case because Colorado is far from the slate quarries that run along the border between New York and Vermont – and even farther from the quarries in Brazil, China and India.
