Female swiping a very precious stone (7)
I believe the answer is:
girasol
'precious stone' is the definition.
(kind of opal)
'female swiping a very' is the wordplay.
I cannot really understand how this works, but
'a' is found in the answer.
'very' could be 'so' (both can mean 'extremely') and 'so' is located in the answer.
'female' could be 'girl' (girl is a kind of female) and 'girl' is found in the remaining letters.
No letters remain.
This may be the basis of the clue (or it may be nonsense).
(Other definitions for girasol that I've seen before include "Gem" , "opal" , "Jewel" , "yellow flower" , "luminescent stone" .)
