Does anyone know what brooch QE used to secure her Garter sash at the 2015 Chinese State Banquet at Buckingham Palace. She wore sapphires and it looks like the brooch might be large. It sits as if the edge is jutting over her shoulder. I don’t think it is the QV or QM bar brooch as it sits incorrectly but I haven’t seen a picture from behind.

Thank you
