The Duchess of Cambridge looked like a princess during an annual reception as she dazzled in a beautiful tiara that once belonged to the late Diana.

The Duke and Duchess of Cambridge joined the 92-year-old Queen, and the Duke and Duchess of Cornwall for the white tie affair.

The Duchess appeared to be in excellent spirits as she greeted an estimated 1,000 guests, and beamed during the reception as she mingled with guests.

The tiara, called the Lover’s Knot, is a favorite of Kate, and one she frequently borrows from the Queen. The matching pearl earrings complimented the beautiful Jenny Packham gown. The fabric itself shimmered with clusters of silver embroidery, adding another dimension to the beautiful dress.

But one detail about her attire stood out; Kate wore a baby yellow badge, known as a Royal Family Order. These are issued by the Queen to other royal family members as a reward for their service.

Mother of three, Kate had only joined the House of Windsor recently and has now acquired her very own. Originally made from ivory, Kate requested hers be made from glass, and is probably related to Prince Williams campaign against the ivory trade.

Mere hours earlier, Kate and Prince William hosted a Christmas party at Kensington Palace for families of RAF military personnel serving in Cyprus over the festive season.

Kate looked relaxed and fashionably festive in a red Emilia Wickstead pleated skirt and a black cashmere cardigan while husband, Prince William, looked casual in navy trousers and a blue jumper.

The party is part of two days of engagements the royal couple organized for the RAF families and is their way of showing their appreciation for the 7,500 military personnel currently serving away from home.

Kate spoke a few words in honor of the men and woman currently serving while their families are holding down the fort at home, empathizing with their situation, and how difficult it surely must be.

A photo booth and a post box where families could take pictures and send messages to their loved ones away on service in Cyprus was a touching addition to the party, which held many more fun activities.

While the Royals were busy with official duties and honoring those in service, Kensington Palace issued a rare statement regarding the alleged argument between the two Duchess’s Meghan and Kate.

According to a report on Saturday by The Sun, Kate got upset with Meghan for the way she had spoken to her staff. But a Kensington Palace spokesman denied the claim and said, “This never happened.”
