Aspects (6)
I believe the answer is:
facets
'aspects' is the definition.
('facet' can be a synonym of 'aspect')
This is all the clue.
(Other definitions for facets that I've seen before include "Surfaces or aspects" , "Sides or surfaces" , "Surfaces of a cut gem" , "Faces of cut gemstones" , "Sides or aspects, diamonds or buildings" .)
