How about a high-quality microscope? There are several models in the market that come with advanced features and high magnifications. You can choose one that suits your mom's level of expertise and interest. If she already has a microscope, you can consider buying her accessories such as slides, coverslips, specimen holders, or even a subscription to a microscopy magazine. Another idea is a personalized coffee mug or t-shirt with a microscope and her name on it. You can also check out science-themed jewelry like microscope necklace or earrings.
Or you can get her a star map with an important date you share.
