Material description

PG Black is a black, fine-grained diabase originating from Varpaisjärvi. The stone is quarried in small quantities and mainly used for monuments. PG Black is a very popular choice, particularly for kitchen countertops. Its deep black color and lustrous polished surface will last for centuries, even in outdoor use.
