Are not carved or over-embellished (6)
I believe the answer is:
ornate
'over-embellished' is the definition.
(synonyms)
'are not carved' is the wordplay.
'carved' indicates anagramming the letters.
'are'+'not'='arenot'
'arenot' with letters rearranged gives 'ORNATE'.
'or' is the link.
(Other definitions for ornate that I've seen before include "Detailed" , "Highly decorated" , "(Of literary style) complex and with unusual words" , "Richly adorned and elaborate" , "Richly or elaborately decorated" .)
