Flower removed some diamonds (4-3)
I believe the answer is:
rose-cut
'diamonds' is the definition.
The definition and answer are not the same part of speech.
'flower removed' is the wordplay.
'flower' becomes 'rose' (I've seen this in other clues).
'removed' becomes 'cut'.
'rose'+'cut'='ROSE-CUT'
'some' is the link.
Can you help me to learn more?
(Other definitions for rose-cut that I've seen before include "(Of a gem) having tiny triangular facets" , "Hemispherically-faceted style (of diamond)" , "(Of gem) finished with triangular faces" .)
