Skull earings in Harry Potter fanfiction could potentially be related to a particular magical ability or curse. For example, they could be enchanted to protect the wearer from a certain type of dark magic. Or, they might be a sign that the wearer has had some encounter with death or the afterlife in a magical sense. Maybe a character who has been to the edge of death and returned wears them as a reminder. It could also be that in the fanfiction, they are part of a fashion trend that started among a group of young wizards who are into alternative styles, and this trend then spreads throughout the wizarding school or even the wider wizarding community.
In some fanfiction, they could be a symbol of a dark or edgy subculture within the wizarding world. Maybe they are worn by characters who are part of a secret society that has a connection to the darker aspects of magic.
