I believe the answer is:

facet

I'm a little stuck... Click here to teach me more about this clue!

'view' is the definition.
(I've seen this before)

I don't understand the remainder of the clue.

(Other definitions for facet that I've seen before include "Side of a cut gem" , "Flat surface on a cut gem" , "Small surface (of diamond)" , "Particular aspect" , "side of rock" .)

I've seen this clue in The Sunday Times and The Times.
