The female 'gesturing OK' emoji, the historically default look of this gesture, commonly used to confirm agreement or signal that everything is fine. Trivia: in Japan this exact pose (called maru pose) is a well-known photo gesture, often struck by idols and models in magazines, which is precisely the cultural reference emoji designers drew from when creating this and its 'no' counterpart.
