When looking at the painting of Winterhalter (where the Queen is depicted with her husband and 5 eldest children) the emerald drops in her tiara seems to be a bit smaller than the gems worn at the Stuart Ball. But in that painting she is also wearing quite a few emeralds on her bodice. Could any of those maybe match the ones from the Stuart Ball.

Actually, looking at all those emerald drops worn by Queen Victoria in the painting I was transported back to Buckingham Palace and the date December 11th, 2019. It is a long shot by far I know, but could those emerald drops in the Winterhalter painting actually be the ones worn by Queen Elizabeth at the Diplomatic Reception?? This is just a flashing thought that just came to me, and I have no evidence what-so-ever (again) - but wouldn't it be great if they were the same and that they are still kept in the family?
