Welcome to Cozy Brook Bluestone Company - A Tradition of Quality Always Specify NEW YORK STATE BLUESTONE!
So what is BLUESTONE? Bluestone is a commercial name for the distinctive variety of sandstone or wackestone found only in South-Central New York State and North Eastern Pennsylvania. The stone is strongly indurated (cemented) stone of various colors, which most typically splits easily into smooth slabs (Natural Cleft, Flagstone). Bluestone consists primarily of feldspars, quarts, phyllosilicates, and other accessory minerals held together by a strong siliceous cement. Colors consist of a full range naturally occurring with various shades of blue, grey, green, buff, and lilac with random surface varying from blue to brown and gold.
