no. i was just reading on another site and a guy said he has a stonewashed pastel he had since 2003 and he has not produced any stonewashed babies yet. all pastels produced are normal pastels.
he said the original stonewashed pastel was a grazaini line pastel.
i have never seen one in person but they look good in pics.
so if you like it buy it. and good luck with producing more.
