A large Llyn Idwal stone imho standard grit rating in approx mid range to 8k ish and this stone seems to be inline with that, ( I have lapped it on my worn 325 DMT plate, so with extra burnishing and oil a higher finish ability could be achieved) size is approximately 9" x 2" x 3/4"
The stone has very little in the way of the blue swirls/lines its more or just a dark green, one side is flat and smooth lapped on my DMT

A bargain price for a stone of this size $89
