Thanks for the reply Nick.
Cambridge is around 70 miles from me as the crow flies,
which would be quite a run for a handfull of fruit.

I have tried all the grocers in my area without any luck,
except one told me to try a health food shop.
Seems they might sell hunzas dried, 'though I don't know
if the stone would remain viable, I'll try anyway.

This person said hunzas are used in beauty products, I
would not know about that, any reference to beauty and me
in the same sentance would be a completely alien concept.
