Översättning - Engelska-Latin - Grow old together with hope

It is for an engraving on a ring so doesn't need to be literal translation but the most poetic way to say it or similar in Latin would be really nice

"Ūnā" means "Like one", "together"

"crescÄ­te" Grow (imperative plural)

"lumine" By the light

"spei" of hope

So : "Together, grow by the light of hope"

You can remove diacritics if you want, it's not really important, except for style.

Congratulations to them :)
