How about gifting your mom a membership to her favorite art gallery or a new art gallery she has been wanting to visit? This way, she can visit as often as she wants and experience the newest exhibits as they come up. If memberships are not available or do not work for her, you could consider an art book from her favorite gallery or a beautiful print of her favorite artist's work. Additionally, if you want to go all out, you could even visit an art gallery with her and spend quality time bonding over your mutual love for art.
Or you can get her a star map with the date when she was born.
