This is probably Okudo Suita but we are not 100 % sure so thats why call it only Suita.
It is very old stock stone and got mixed up with others so thats why it is unknown
It looks like very Expensive Okudos I tried and act similar, so i am pretty sure :)
Very fast stone and very very clean. Very unusual Patter Black clouds that indicates very low strata Suita stone
This one is super fine and Feels very smooth !
No toxic lines or inclusions at all
