US president Donald Trump has spent a busy three days in Britain for the official state visit, being wined and dined by various members of the royal family including Prince Charles, Camilla Parker Bowles, and Prince Harry.
For her part, Queen Elizabeth has always made sure that at every special occasion she has not only warmly welcomed her American guests, but she has looked her royal best.
WATCH the making of the Queen’s tiara at Kensington Palace!
On Monday the State Banquet at Buckingham Palace was held and attended by Her Majesty, Kate Middleton and her husband, the Duke of Cambridge.
While Kate wowed the crowd in a stunning Alexander McQueen white gown, Queen Elizabeth II wore something even more breathtaking, the Burmese Ruby Tiara.

The special headpiece has a rich history, with the Queen first commissioning the ruby and diamond tiara in 1973 from London based jewellery company, The House of Garrard.

The tiara is said to have been made entirely by hand and has 96 rubies (the gems were a wedding gift from the people of Burma) encrusted upon it.
The breathtaking tiara also has diamonds from the Nizam of Hyderabad.
But why is this tiara so special?
According to Burmese tradition, rubies are said to protect their owner (or in this case wearer) from evil and illness.
Whether the tiara succeeds in repelling any malevolence remains to be seen, but it certainly is pretty!
