Yki Aitokivi (Real Stone) is made from genuine crushed stone. Its four standard colors come directly from the Finnish landscape: Red granite from Taivassalo, black gabbro from Hyvinkää, gray granite from Kalanti, and light limestone from Parainen. The gray and light standard colors can be tinted to the colors of the Yki Aitokivi Real Stone color card without losing their luster and their natural stone appearance.
