Put-up job pinching diamonds: trouble for place of riches (2,6)
I believe the answer is:
el dorado
'place of riches' is the definition.
(mythical city of gold)
'put-up job pinching diamonds trouble' is the wordplay.
'put up' says the letters should be written in reverse.
'job' becomes 'role' (a job is a role or position).
'pinching' indicates putting letters inside (taking inside).
'diamonds' becomes 'd' (abbreviation for the card suit diamonds).
'trouble' becomes 'ado' (both can mean bother or commotion).
'role' enclosing 'd' is 'rodle'.
'rodle' backwards is 'eldor'.
'eldor'+'ado'='EL DORADO'
'for' acts as a link.
(Other definitions for el dorado that I've seen before include "One who can't give something up" , "Golden land imagined by the Spanish explorers of America" , "Supposed city of riches" , "Fabled city of gold" , "Land of great wealth" .)
