Stylish silver ring from a city in Illinois (7)
I believe the answer is:
chicago
'a city in illinois' is the definition.
(I've seen this before)
'stylish silver ring' is the wordplay.
'stylish' becomes 'chic' (similar in meaning).
'silver' becomes 'Ag' (Ag is the chemical symbol for silver).
'ring' becomes 'o' (letter resembling a ring).
'chic'+'ag'+'o'='CHICAGO'
'from' is the link.
(Other definitions for chicago that I've seen before include "Port on Lake Michigan" , "Al Capone's city" , "Type of bridge" , "Windy City of USA" , "Illinois port" .)
