Moreover, another highlight of the highly anticipated wedding is her simple yet classy wedding band, 

In a recent report cited by Express UK, jeweler expert Joshua James explained that kate Middltone's ring was "crafted from a special nugget of Welsh gold--a tradition that dates back to 1923 - by Wartski, a jeweler based in London."

Moreover, he described the jewel as a plain and slender band that "shows off the incredibly rare and beautiful gold it was made from."

James also estimated that the jewelry would probably be higher than $2,800 or £2,000, depending on the "weight and purity of the gold used."

Queen Elizabeth II's Jewelry Collection

It's no secret that the 94-year-old monarch has an extraordinary and priceless piece of a jewelry collection that she'd inherited from previous royals. 

This includes some of the few iconic accessories such as the Imperial State Crown which she wore during her coronation and the Grand Duchess Of Vladimir Tiara, also known as the Queen's favorite crown. 

On the other hand, the jeweler expert claims that Her Majesty the Queen gave his grandson the Welsch gold ring ahead of Kate Middleton and Prince William's wedding ceremony. 

Unlike the modern royal wedding rings, Kate Middleton's ring was minimalist and "free of decorative" elements like embellishments.

Kate Middleton's Engagement Ring

Aside from her wedding ring, another remarkable piece of jewelry of the Duchess of Cambridge is her engagement ring. 

It was 2010 when Prince Charles' eldest son popped the question during the couple's trip to Kenya. 

At the time, she was photographed wearing a beautiful piece of 12-carat sapphire ring, which was now valued at a whopping $300,000. 

It showcases an oval sapphire set in 18k white gold and enclosed by 14 solitaire diamonds.

Dubbed as the "commoner ring," Kate Middleton's engagement ring was considered a priceless possession since it belonged to the late Princess Diana during her engagement with Prince of Wales. 

Vogue previously mentioned the inspiration behind the iconic oval sapphire ring. 

In 1840, prince Albert tasked a British jeweler to create a brooch for his future wife, Queen Victoria.

The royal immediately fell in love with the jewel and wore it on her wedding day as something blue on her white dress.
