Dave mentioned the possibility that Queen Mary may have had a tiara which is unknown.

There is a high possibility of that as, obviously, we know only about her publicly worn jewels.

There is one tiara which Queen Mary wore in public which I have never been able to place.

Once again we are dealing with an imperfect photo taken from a distance but I don't think that this is what I call the wing tiara without a brooch in the centre. Although this tiara also reminds me of wings, the design is different from the tiara worn by Queen Mary and Princess Margaret.
