Everyone is after element in diamond ring (4)
I believe the answer is:
call
'diamond ring' is the definition.
'call' can be an answer for 'ring' (call on the phone). I am not certain of the 'diamond' bit.
'everyone is after element' is the wordplay.
'everyone' becomes 'all' (all people).
'is after' is a charade indicator (letters next to each other).
'element' becomes 'c' (C is an example).
'all' put after 'c' is 'CALL'.
'in' acts as a link.
Can you help me to learn more?
(Other definitions for call that I've seen before include "Telephone - give a name" , "Phone; cry" , "Pay a visit" , "Ring; name" , "Visit; telephone" .)
