A great anniversary gift for your wife who loves the world would be a world map wall art or a personalized world map that highlights all the places you have traveled to together. You can also consider getting her a travel-themed book or a subscription to a travel magazine. Another idea could be to plan a surprise trip to a new destination that you both have always wanted to visit, and present her with the itinerary as your anniversary gift.
Or you can get her a star map with the date of your anniversary.
