Not total access. See the banner atop the British Royals Board. The Queen is wearing a brooch she gave her mother. She has recently also worn other brooches of QEQM as well as the Fringe tiara, which she and Princess Anne borrowed from QEQM for their weddings.
The two brooches in these pictures do look very similar. I wish they had been photographed from the same angle. Then it would be easier to tell if they are the same.
