I believe the answer is:

middle ear

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

'location of small hammer' is the definition.
'middle ear' can be an answer for 'hammer' (thesaurus). I am not certain of the 'location of small' bit.

'emerald i'd smashed' is the wordplay.
'smashed' indicates an anagram.
'emerald'+'id'='emeraldid'
'emeraldid' is an anagram of 'MIDDLE EAR'.

'and' is the link.

Can you help me to learn more?

(Another definition for middle ear that I've seen is " Where to find hammer".)

I've seen this clue in The Telegraph.
