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