Kate Middleton wore a stunning coat dress and matching £560 Juliette Botterill hat but it was complimented with her glitzy £8,400 G. Collins & Sons tanzanite pendant necklace and matching £6,100 earrings which she has worn on a number of occasions. 

One fan tweeted, "Katherine looks absolutely stunning in blue."

Another fan wrote, "Catherine looks magnificent no matter what she wears. One beautiful lady inside and out."

And a third fan added, "Just lovely. Kate is always elegant, classy and most of all appropriate."

Kate's Tanzanite gemstones are said to be 'incredibly rare', but offer a beautiful purplish blue colour for gemstone lovers. According to Heart (opens in new tab), Prince William reportedly bought Kate these earring and necklace set which feature some huge gemstones and diamonds by royal jeweller G. Collins & Sons. 

They also match the deep blue of her engagement ring!

New appointments are announced on St George's Day but the chivalric and installation ceremonies take place every year on the Monday of Royal Ascot week, known as Garter Day. 

The Duchess of Cornwall was appointed Royal Lady of the Order of the Garter. The Order of the Garter is the oldest and most senior Order of Chivalry in Britain, established by King Edward III nearly 700 years ago.
