A personalized engraved gemstone necklace might be a perfect gift for your wife. You can choose a gemstone that represents your wife's favorite type of rocks or choose a special gemstone that has a significant meaning behind it. You could also consider taking her on a rock hunting trip where she can collect her own specimens, or signing up for a rock-collecting workshop to learn more about the hobby. If you want to give her a physical object, you can consider a rock polishing or grinding kit that will allow her to transform her collected rocks into shiny and smooth stones.
Or you can get her a star map with the date of your anniversary.
