How about a custom-made piece of jewelry featuring one of her favorite minerals or gemstones? There are many Etsy sellers who create beautiful and unique pieces using natural and raw stones. You could also consider a subscription to a monthly mineral and gemstone box service which delivers a curated selection of specimens to her every month. Another idea could be to plan a day trip to a nearby mine or gemstone hunt location where she can gather her own treasures. Additionally, you could consider a personalized photo album featuring pictures of her favorite discoveries and memories from your time together exploring mineral and gemstone collections.
Or you can get her a star map with the date of your anniversary.
