The Titanium BCR with Titanium Clip In Bezel Set Single Jewelled Asia is shown in a 10mm BCR, here.
Because it is a BCR, the attachment can twist around to face the direction you choose.
The Asia attachment is 7.5mm tall and 3.9mm wide.
Check your own size to make sure of your fit, but it is likely that with an 8mm internal diameter ring, it will look great in a rook and a suitable rim piercing.
With a 10mm ring it is probably good for a daith and maybe conch piercing.
Other locations will also suit this ring.
The asia attachment has dimples either side which allow it to be held in by tension from the ring.
