Hi Anthony,
no that stone is Dargill, it's on your left as you drive south from Crieff towards Muthill (and the A9) just after the Stuart Crystal visitor centre.
there aren't any stones on your left between Gilmerton and Crieff, however there is a stone circle on the golf course in on the right http://www.themodernantiquarian.com/site/3270
if you want any more info on the area, just shout. my grandma lives in Muthill so I know the area well
Cheers
Andy S
