The mystery of which tiaras Queen Mary had at Badminton!

Apart from the Delhi Durbar tiara, I think the most likely contenders may have been --

1.The Girls of Great Britain tiara in the lower version, plus the base to the tiara which Queen Mary had begun to wear separately.



2. The Kent bandeau either with or without the upright emeralds.



3. The wing tiara with the large sapphire in the front.



4. The diamond bandeau with the County of Lincolnshire brooch in the centre.



5. The bandeau with the upright pearls. Princess Margaret later wore this tiara without the pearl surmounts.



6. Possibly another narrow bandeau. I don't think we have ever decided if this is the base to the Girls of Great Britain and Ireland tiara or another base/bandeau.



Do we know of any other tiaras Queen Mary had in her possession during the war years?
