A ring wearing a finger.
Aliens can wear a humanlike accessoire. Robots can wear the humanlike accesoire to feel a little bit human. And humans can have the 6. finger!
At first glance, a ring may appear non-functional, yet it carries significant meaning: status (social, economic, often gender-stereotypical). The fingerring and Yes, it's a real Earring! transcends this notion—it doesn't overtly showcase a status, at least not in the conventional sense. The fingerring adorns the body with the body itself. The fingerring is a prosthesis – an artificial body part that doesn't replace a missing one but complements it. This complement also alters the body part it complements: it emphasizes it, hinders it, and so forth.
