How about a soap carving kit? You can put together a gift basket with different types of soap, carving tools, and instructional books or videos. You could also consider signing her up for a soap carving class or workshop. Alternatively, you could commission a professional soap carver to create a personalized soap carving for your wife, based on her interests or favorite things.
Or you can get her a star map with the date when she was born.
