The City Beautiful's light surrounded by gold ring (7)
I believe the answer is:
orlando
'the city' is the definition.
(I've seen this before)
'light surrounded by gold ring' is the wordplay.
'light' becomes 'land' (I've seen this before).
'surrounded by' means one lot of letters goes inside another.
'gold' becomes 'or' ('or' is the heraldic name for gold).
'ring' becomes 'o' (letter resembling a ring).
'or'+'o'='oro'
'land' inserted into 'oro' is 'ORLANDO'.
'beautiful's' acts as a link.
This may not be correct. It may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for orlando that I've seen before include "___ Gibbons, English composer of madrigals - Florida resort city" , "Florida location" , "US city" , "American themepark location" , "2016 Invictus Games city - Virginia Woolf novel" .)
