Crossword Genius

Very detailed, certain it's complicated (9)

Ross

I believe the answer is:

intricate

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

'certain it's complicated' is the wordplay.
'complicated' indicates an anagram.
'certain'+'it'='certainit'
'certainit' with letters rearranged gives 'INTRICATE'.

(Other definitions for intricate that I've seen before include "Entangled" , "ornate" , "Convoluted" , "Fancy" , "Complicated, detailed" .)

I've seen this clue in The Telegraph.
