Stone used in landscaping and construction is sometimes classified by the size of the grains or chunks. The size is represented by a number, and that is what the "67" stands for in 67 gravel. This 67 gravel is crushed limestone that is roughly ½" in diameter. It is sifted to remove all smaller chunks and "fines" or stone dust.
