'tuscan island' is the definition.
'elba' can be an answer for 'island' (I've seen this before). I am unsure of the 'tuscan' bit.

Can you help me to learn more?

(Other definitions for elba that I've seen before include "Italian island" , "Island of Napoleon's first exile" , "Napoleon's Mediterranean exile island" , "Able was I ere I saw ... (palindrome)" , "Napoleonic prison" .)

I've seen this clue in The Telegraph.
