Queen Elizabeth & Duchess Camilla look especially regal in luxurious tiaras at royal reception

On Tuesday, three lovely ladies of the royal family stunned at an annual event in the Buckingham Palace. Their tiaras were especially dazzling.

The Queen hosted the Diplomatic Corps Reception yesterday evening. Though usually a closed event, media was allowed to take a few more pictures during the evening.

Additionally, the Royal Family's Twitter account shared some photos. It showed as the Queen greeted several foreign ambassadors who are based in the UK. The pictures can be found below.

Along with the Queen, the Prince of Wales, the Duke, and Duchess of Cambridge, and the Duchess of Cornwall were also in attendance.

The white tie event allowed the women to shine in their dresses as the men showed off their white bow-ties. Kate Middleton looked radiant in a Jenny Packham gown.

The dress is a first to the public's eye according to Hello Magazine. It featured a glittering floor-length design with draping tulle at the shoulders. Middleton also adorned her often-worn pearl-encrusted Lovers Knot Tiara.

The beautiful item was gifted to the late Princess Diana by the Queen in 1981 for her wedding. It was made in 1914 by the House of Garrard, as was the queen's own.

Her Majesty's headpiece may have taken the cake, however. She wore her favorite tiara, the Queen Mary Girls of Great Britain and Ireland piece.

The tiara was initially fitted with oriental pearls like those which now lie in Middleton's tiara. Queen Mary had them replaced with 13 diamonds during her reign.

Donned in Angela Kelly's white dress with a gold overlay, the Queen wore white gloves as she greeted guests. She accessorized with a metallic gold handbag which matched her shoes.

Duchess Camilla was also a sight to behold in her well-known Bruce Oldfield gown. She teamed the gorgeous dress with her own Greville Tiara, a Boucheron piece.

Camilla also accessorized with a pair of hanging pearl earrings and a matching choker necklace.

Middleton's ensembles are the most scrutinized these days as she is still fairly new to the royal family. Let's have a look back at that famous tiara of hers.

Just two months prior to the Buckingham Palace affair, she paired the piece with an Alexander McQueen gown for a state banquet.

In December 2017, Middleton was pictured with husband Prince William wearing the Lovers Knot tiara as the two attended a diplomatic dinner. Earlier in July, she again donned the tiara for another state banquet.

It was back in December of 2016 that we saw Middleton with the tiara for the second time. Coincidentally, it was also for a Diplomatic Corps Reception. We first saw the piece along with a white lace gown at the Buckingham Palace.

For her own grand event, Middleton had worn a borrowed piece at her wedding. She wore the Cartier Halo tiara which features nearly a thousand diamonds.

The queen lent it to her for the occasion. These family heirlooms will continue to stand the test of time as they keeping helping the royal women glow.
