RH Preyda stones are quarried within the Ouachita Mountains of Arkansas, then cut and finished at our family-owned factory. The Ouachita Mountain range spans western Arkansas to southeastern Oklahoma and is home to many natural wonders, abundant minerals, and wildlife.  Durability and quality are born into the DNA of a true Arkansas stone.
