Odd male with red and green stone (7)
I believe the answer is:
emerald
'green stone' is the definition.
(I've seen this before)
'odd male with red' is the wordplay.
'odd' indicates an anagram.
'with' is a charade indicator (letters next to each other).
'male' after 'red' is 'redmale'.
'redmale' is an anagram of 'EMERALD'.
'and' acts as a link.
(Other definitions for emerald that I've seen before include "Green variety of beryl" , "Gem associated with Ireland" , "Green gemstone" , "Green like this isle" , "Bright green colour" .)
