Small bundle holds diamonds: rector finds storage in kitchen (5,4)
I believe the answer is:
spice rack
'storage in kitchen' is the definition.
'small bundle holds diamonds rector' is the wordplay.
'small' becomes 's' (abbreviation - e.g. clothes size).
'bundle' becomes 'pack' (pack is a kind of bundle**).
'holds' is an insertion indicator.
'diamonds' becomes 'ice' (I've seen this before).
'rector' becomes 'r'.
'ice'+'r'='icer'
'pack' enclosing 'icer' is 'picerack'.
's'+'picerack'='SPICE RACK'
'finds' is the link.
(Another definition for spice rack that I've seen is " Storage for cloves, garlic etc".)
