How about a custom-made rowing oar? You could have her name or initials engraved on it, and choose her favorite colors for the design. She can use the oar when she goes rowing, and it will serve as a personal and unique reminder of your thoughtfulness. Additionally, you could consider getting her a rowing-inspired piece of jewelry, such as a necklace with an oar charm or earring studs in the shape of rowing blades.
Or you can get her a star map with an important date you share.
