Another jewel, closely associated with the public persona of Queen Elizabeth the Queen Mother, is Queen Victoria's Oriental circlet and the "ruby" parure.
I have never seen any reference to HM wearing them during WWII.
When Queen Elizabeth the Queen Mother and Queen Mary commenced wearing grand jewels after the end of the war, the press kept referring to their wearing "small" tiaras. In QEQM's case that meant either the Teck circles necklace/tiara or Queen Mary's Fringe tiara.
But in South Africa, QEQM re-introduced Queen Victoria's Oriental circlet and the "ruby" parure.
HM wore the jewels at least three times for Civic Balls.
1. In Pretoria at the end of March 1947 when HM also wore Queen Victoria's Fringe brooch in the centre of her gown.
2. On 18 February 1947 for a Civic Ball at Cape Town.
I found this photo interesting as when I zoomed in I could see how deep the top ruby in the brooch is. Normally, we see this brooch photographed from the front and the depth of the ruby is not apparent.

3. On 21 April 1947 QEQM selected these jewels for the Civic Ball in Cape Town when QEII was presented with her 21st birthday diamonds by the government of South Africa.
