How about getting your friend a book about the Mayan culture? "The Maya" by Michael D. Coe is a great option that covers the history, art, and architecture of the Mayan civilization. You could also get her/him a piece of jewelry that has a Mayan-inspired design, or some artwork that depicts the Mayan culture. Additionally, you can look for a guided tour or an experience in a nearby museum that focuses on Mayan art and culture. This would offer an unforgettable experience!
Or you can get her/him a star map with the date when she/he was born.
