You could consider giving your friend a book on Latin language or literature, such as "The Aeneid" by Virgil or "The Metamorphoses" by Ovid. Another idea could be a Latin language dictionary or a Latin phrasebook. You could also consider giving them a piece of jewelry with a Latin inscription or a Latin-inspired design. For example, a necklace engraved with the Latin word "carpe diem" (seize the day) or a bracelet with the phrase "veni, vidi, vici" (I came, I saw, I conquered).
Or you can get her/him a star map with an important date you share.
