The Court Circular included a list of guests for the state banquet on May 9, but no further description of dresses or jewellery. Among the royal guests were only family and some Commonwealth princes, as far as I can see:
The King and Queen, the Queen of Norway, the Prince of Wales, the Duke and Duchess of York, the Duke of Gloucester, the Duke and Duchess of Kent, the Princess Royal and the Earl of Harewood, the Princess Victoria, Field-Marshal the Duke of Connaught, Prince and Princess Arthur of Connaught, Princess Alice and the Earl of Athlone, Princess Helena Victoria, Princess Marie Louise
The Maharaja of Jammu and Kashmir, the Maharaja of Bikaner, the Maharaja of Patiala
(the list also states that Princess Louise, (Duchess of Argyll), the Princess Beatrice and the Dowager Marchioness of Milford Haven were invited but unable to attend).
There was another grand public event earlier the same day (May 9). The King and Queen, accompanied by most members of the royal family, travelled in state to Westminster Hall, to receive addresses from the Parliament. There are pictures from this event, though I am unable to see details on what the Queen is wearing.
Other events in May/June 1935 included another state banquet at Buckingham Palace on May 20, and two state balls at Buckingham Palace on May 14 and June 13.
As we will shortly be celebrating the Queen of the United Kingdom's Platinum Jubilee I started to look back on previous jubilees celebrated by British monarchs. In May 1935 King George V celebrated his 25 years on the throne since succeding his father King Edward VII. It was a grand celebration, and I believe the first time 25 on the throne was actually celebrated in this very grand and public way.
On May 6th the Royal Family attended the Thanksgiving Service at St. Paul's Cathedral and all of us have probably seen either photographs or paintings from this event. Queen Mary was of course wearing magnificent jewels even though it was a day event and thus no tiaras were worn - at least not to the cathedral. We know that King George "favoured" the ladies wearing tiaras for dinner, so I am sure that even more glitter would have been seen that evening, although I cannot see that this was a public event but rather a private dinner.
Queen Mary wore the Chain Link bracelet as a choker together with several diamond rivières. Beth had a very interesting post on the Chain Link bracelet as used in the connection with this day, see https://mb.boardhost.com/historyroyaljewels/msg/1548579446.html
The earrings seem to be Queen Alexandra's Pearl and Diamond cluster earrings she received for her wedding. In her hat Her Majesty wore more diamonds; the Cullinan V brooch. And to fasten the Sash of her Order of the Garter she wore a Diamond Bar brooch.
I have not been able to spot whether the Queen wore any bracelets, but I would not be very surprised if she did. Has anybody seen any jewels around Queen Mary's wrists?
Also, I am not quite certain about the additional order worn by the Queen. Could it be the bow of the Royal Family Order of King George V?
The present Queen, now soon celebrating her 70 years on the throne, was also present at the 1935 jubilee. It is said that she and her sister received as a gift from her grandfather, the King; a pearl necklace each (See https://members2.boardhost.com/royal-jewels/msg/archive/1404867903.html
The King himself looked very smart (like he always did) in his Field Marshal's uniform. With it he wore the Collar and Breast Star of the Order of the Garter and the Sash and Breast Star of the Order of the Thistle. Also around his neck he is seen wearing the Victorian Chain and the Neck-tie of the Order of the Bath.
Now, on this day in 1935 (May 9th) the King and Queen gave a grand State Dinner at Buckingham Palace. Unfortunately I have not been able to find any information about this. Does anybody have any details on this event? I am very intrigued as to what was worn (if that was mentioned in any of the press outlets of the day).
