Just beautiful (4)
I believe the answer is:
fair
This clue is a double definition.
'just' is the first definition.
(just can mean fair in the sense of showing justice)
'beautiful' is the second definition.
(similar in meaning)
(Other definitions for fair that I've seen before include "Reasonable - market" , "Moderate" , "The mart is blond" , "Attractive type of weather?" , "Market for the sale of produce" .)
