How about getting her a custom embossed metal artwork piece that features a special message or image? You could even have a portrait of the two of you embossed onto the metal. Another idea could be to get her a set of embossed metal wall art pieces that can be arranged and hung together to create a larger display. If she enjoys DIY projects and crafting, you could also get her an embossing kit with various metal designs that she can then use to create her own artwork.
Or you can get her a star map with an important date you share.
