The Queen made a rare and historic television address to the United Kingdom and Commonwealth on April 5, in which she discussed the impact of COVID-19 on everyone. Her Majesty stressed that "united and resolute," we can defeat the coronavirus.

The 93-year-old monarch gave the speech at Windsor Castle. Seated at her desk, she wore an elegant green dress, her signature three-strand pearls and a turquoise brooch bequeathed to her by her grandmother, Queen Mary.

The Queen, along with many other members of the Royal Family, is known for carefully selecting her outfits to reflect an occasion and/or engagement. Her Majesty's look for the COVID-19 TV broadcast was no exception. She showcased what a powerful tool her fashion can be.

Firstly, many royals fans were quick to notice the monarch's long-sleeved dress. Its shade of green was extremely close to the colour of the scrubs often worn by doctors, nurses and other front line workers.

Secondly, the Queen wore the turquoise brooch fastened prominently on her left shoulder. It is a rarely seen piece so the fact she selected this moment to wear it greater highlights its significance.

Her Majesty was given the piece in 1953, upon Queen Mary's passing, according to HELLO! UK. Mary herself received the brooch as a gift from her in-laws in 1893, on the day of wedding to the future King George V, according to Town & Country.

However, the 93-year-old didn't debut the sparkling brooch publicly until 2014. She sported the striking turquoise brooch on a visit to Chatsworth House in Derbyshire, England that July.

Her Majesty wore the turquoise brooch again at a meeting for the Commonwealth heads of government in Malta in November 2015.

The last time she wore the brooch is believed to have been on May 23, 2019, when she visited the British Airways headquarters to mark the company's centenary year at Heathrow Airport.

Some royal watchers have said the Queen's accessory shows "continuity," which will hopefully provide some reassurance in these unpredictable times.

That the brooch features a turquoise stone was also important to many royal watchers. Turquoise is considered to be a protective stone with healing qualities. Additionally, it is one of the oldest stones in the history of jewellery and was often used as a stone of protection and healing.

The colour turquoise itself can represent serenity, love, tranquility, calmness and patience, to name a few of its positive links.

The Queen's four-and-a-half-minute televised speech highlighted some points about love and patience in beating COVID-19.

"We will succeed – and that success will belong to every one of us," she said in ending her message. "We should take comfort that while we may have more still to endure, better days will return: we will be with our friends again, we will be with our families again, we will meet again. But for now, I send my thanks and warmest good wishes to you all."
