Diamonds sure to be frozen in (8)
'be frozen in' is the definition.
(I've seen this before)
'diamonds sure' is the wordplay.
'diamonds' becomes 'ice' (slang term for diamonds).
'sure' becomes 'bound' (synonyms).
'ice'+'bound'='ICEBOUND'
'to' acts as a link.
(Other definitions for icebound that I've seen before include "Locked in by frozen water" , "Stuck in frozen water" , "(Arctic ship) stuck for winter" , "trapped by wintry conditions" , "Like ships trapped near poles" .)
'be frozen in' is the definition.

'diamonds sure' is the wordplay.

(Another definition for ice-bound that I've seen is " feeling the cold".)
