How about a beautiful piece of Phantom of the Opera merchandise?
Some ideas include a signed book or program from the show or an elegant Phantom of the Opera music box. You could also look for a Phantom of the Opera-themed pendant, earrings or charm bracelet to add to her jewelry collection. Another idea could be tickets to see the show live, or a DVD box set of the different performances to watch at home together. If your wife likes reading, you could also get her a beautiful copy of the original novel written by Gaston Leroux.
Or you can get her a star map with an important date you share.
