Slate is a fine-grained metamorphic rock of great structural integrity and beauty.  Its nearly perfect natural cleavage allows it to be split into smooth sheets.  Slate’s strength, insolubility and imperviousness makes it one of the most durable and versatile materials in the stone industry.

In the Slate Valley of New York and Vermont, the chemical and mineral composition of the vein of slate produces a rare variety of colors – green, gray, gray black, purple, mottled green and purple, and red. The Slate Valley is the only place in the world where this variety of colors can be found.
