How about a set of high-quality watercolor paints? You can also throw in some watercolor paper, brushes, mixing palettes, and a book on watercolor techniques. Another idea could be a subscription or a gift card to an online course, workshops, or a local art class to further develop her skills. Additionally, you could commission a local artist to create a portrait or a custom painting of a subject that your mom loves (for example, a favorite flower or landscape).
Or you can get her a star map with the date when she was born.
