Thread: Ohzuku suita?

A very telling sign of suita is their layered structure, just look at the side , if you can show us pics it will be easier to tell. Some hard stones can have small holes like that but they are not su. I have an Ozuko like that, it is very hard and very very fine finisher.

Another feature to consider is the color of the stone. From the pics your stone looks green with rusty spots, suitas are not green. Typical suita colors are yellow, orange, white and mixtures of those. Finally I can see clouds in the features of your stone, suitas do not have that feature.
