I believe the answer is:

icefloe

I'm a little stuck... Click here to teach me more about this clue!

'cold sheet' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'diamonds woman enfolded first' is the wordplay.
'diamonds' becomes 'ice' (slang term for diamonds).
'woman' becomes 'flo' ().
'enfolded first' becomes 'e' (fst letter of 'enfolded').
'ice'+'flo'+'e'='ICEFLOE'

'in' is the link.
