Those two stones (middle and right) look the most like your stone and I would expect them to be similar in performance, too.

You might try slightly increasing the pressure, or making very light slurry on your stone. I am pretty sure you will see some scratches. On slurry, this stone gives a hazy finish. Diluting that slurry to water will bring the finish more to mirror-like, but the scratches will be (should be) visible.
Thanks for the quick reply. The Cretan blue is just then name of the stone and not the color of the stone. When I was lapping the stone it felt very hard. With what you make slurry.??
