Suit of ice (8)
I believe the answer is:
diamonds
This clue is a double definition.
'suit' is the first definition.
(I've seen this before)
'ice' is the second definition.
'of' acts as a link.
(Other definitions for diamonds that I've seen before include "Maids don these gems" , "Expensive gems and card suit" , "where some Americans find sporting action" , "Red cards" , "Quarter-deck" .)
