There was some problems with the white balance of the pics when I request an ID on that stone
, when Bart dictamined that it was a La Grise.
I guess that the pics I've post today have its colors more accurate, and perhaps you are right, its a La Verte. Its really slow specially on water, you need a good amount of work to get good results.
I'm really impressed with the pinky one. A fast dilution and about 30-40 X-strokes on water, just to try the stone, and the edge from the coti right before linen/leather was as good, if not better, than I was getting with that La Verte after stropping.
