Meghan Markle's engagement ring is huge! For months royal fans have been wondering when Prince Harry would propose to the gorgeous brunette. And they finally got their answer on Monday.

After Kensington Palace released an official announcement about the upcoming marriage, the former Suits actress and prince made their first public appearance in the Sunken Gardens of Kensington Palace.

As they walked, the gorgeous couple held hands and giggled and Markle, 36, stroked Prince Harry's arm. But royal fans only wanted to see one thing: the stunning engagement ring.

Designed by Prince Harry and Cleave and Company, jewelers to the Queen, the gold ring features a center stone from Botswana and two outside stones from the personal jewelry collection of his mother, Princess Diana.

Prince Harry, 33, told the media he is “thrilled.” Markle added: “So happy.”

Harry wasn't shy about declaring his love for his new fiancée. When asked when he knew he was in love, he gushed: “The very first time we met.”

But the prince wasn't ready to reveal all just yet. When the press inquired about details of the proposal, he said: “That will come later.” But he did confirm that it was, indeed, romantic. “Of course it was,” he replied.

Markle's choice of attire was elegant yet minimalist. Clad in a chic white coat by the Canadian brand LINE, the Toronto beauty showed she is not abandoning her roots. She has long been a fan of the Toronto-based knitwear brand, and she previously chose the label for the 2017 closing ceremonies of the Invictus Games.

“We are incredibly honored that Meghan chose to wear a LINE coat to mark this very special occasion. Meghan has an effortlessly chic sense of style, which we’ve always admired,” John Muscat, president and co-founder of LINE, said in a statement. “We know this particular coat is one of her favorite pieces so we have officially decided to name it the ‘Meghan.’ We are elated for Meghan and wish her a lifetime of happiness with Prince Harry.”

Markle finished the look with a a modest, knee-grazing P.A.R.O.S.H. dress and nude Aquazzura heels.

The buttoned-up look was clearly a departure for the actress who opted for distressed denim and an untucked blouse for the Invictus Games. But the decision to wear a Canadian designer and avoid a fussy suit and overly worked updo speaks volumes.

It's no secret that the Queen has been unhappy with Kate Middleton's style choices in the past. Prince William's grandmother didn't approve of the Duchess' short skirts, jeans and wedge heels. Soon the Duchess' wardrobe changed.

Markle, who is a year older than Middleton, will certainly need to make some changes. But the fashion set is hoping Prince Harry's bride will choose modern looks that offer a new take on royalty.

Every step of the way, Harry and Markle's relationship has been unconventional. Compared to his brother, Harry was always a rebel. And this romance was no exception.

Prince Harry proposed to an American actress with a Caucasian father and African-American mother. And instead of making their debut at a formal event in London, the couple first appeared together in Canada at the Invictus Games.

The question is: Will the unconventional path also inform Meghan Markle's style choices?
