This shiro or white suita stone is a true grade #24 stone at 220mm by 79mm by 50mm. It is big and beautiful and being white, very rare. 

The stone is very hard and cuts exceedingly fast as you can see in the close up photo. The metal is cut without creating any paste if you begin with just water. Because these stones are so hard, I found that they are easier to use if you use a diamond plate as a "diamond nagura" to first build up a paste as you can also also see in the photos. The dried paste from the diamond nagura is a pure white as snow even when containing particles from the orange area at the lower corner.

This stone has a grit of 38,000 or greater when the particles in the slurry are ground even further as the paste forms and develops.

*If a diamond plate induced slurry is used.
