Goldfinger's first name (5)
I believe the answer is:
'goldfinger's first name' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for auric that I've seen before include "Relating to a form of gold" , "French composer" , "Pertaining to gold" , "Hugh -, Labour party leader" , "- Goldfinger (Bond)" .)
