I have no idea. Googling it gets "Grace Hopper Nanosecond Earrings." FWIW, when I became STAR Student in high school, my mother bought me a necklace with a starfish on it to mark the occasion. She was looking for a "star" of some sort and the starfish was all she could find. So maybe someone else bought them because of her rank and she wore them in part to honor that memory and that relationship-- family, friend, whatever. That's something people sometimes do.
