From Canmore:
There are ‘two huge granite boulders, situated on a shelving rock over an abyss on the Loch Avon side of Cairngorm, with hand-made cups on them about a foot wide and correspondingly deep – “sitting on which is said to be efficaceous in cases of barrenness” ‘. Pilgrimages have been made to them within living memory.

The description is exactly like those discussed a few weeks ago ,i.e. natural and typical of that found on granite . The writer(s) also comment "I have not seen these stones, and feel doubtful about their really belonging to this class of cup stones"
Thanks George, I did wonder. I've changed the site type to natural rock feature so as to leave the folklore post up. Eds can always delete if not appropriate.
