jewelled

I'm a little stuck... Click here to teach me more about this clue!

'stoned' is the definition.
Both the definition and answer are adjectives. Maybe you can see a link between them that I don't see?

'in france i rushed out' is the wordplay.
'in france i' becomes 'je' ('I' in French).
'rushed out' becomes 'welled' (I can't justify this - if you can you should give a lot more credence to this answer).
'je'+'welled'='JEWELLED'

'to get' acts as a link.

Can you help me to learn more?

I've seen this clue in The Telegraph.
