What is the metronome mark for the tempo text 'Elegante'?

I am working on a composition and the theme is 'Waltz'. I was thinking of putting a tempo text that meant 'elegantly' or gracefully', so I went on the internet and came across the term 'Elegante'. Even though I've got the term, what is the actual tempo or metronome marking for 'Elegante'? Does anyone know? Oh, and I wouldn't mind having some 'Waltz' music tips as well... Hehe - I'm just a student learning music, so I need the help. Thanx!!! :)
