On her wedding day, Kate wore a custom-made dress by Sarah Burton for Alexander McQueen.
The iconic gown had a fitted torso with long lace sleeves and a full pleated skirt.
She completed the look with a tiara, borrowed from the Queen’s collection.
The Duchess opted for a diamond and platinum headpiece, the Cartier Halo tiara.
At the ceremony, Kate was given a Welsh gold ring in line with royal traditions, experts at jewellers Joshua James explained.
They told Express.co.uk: “Kate’s simple gold wedding ring is crafted from a special nugget of Welsh gold – a tradition that dates back to 1923 – by Wartski, a jewellers based in London.
“The value of a Welsh gold ring depends on the weight and purity of the gold used, but will likely be upwards of £2,000.”
The experts claimed Queen Elizabeth II gave the jewel to Prince William ahead of their wedding day.
“The plain, slender band shows off the incredibly rare and beautiful gold that it was made from,” they added.
“It was free of decorative elements that embellish many modern wedding rings.
“The ring was gifted to Prince William by the Queen following the engagement.”
Prince William proposed to Kate in 2010 using the engagement ring that once belonged to his mother, Princess Diana.
It has a central sapphire surrounded by 14 diamonds and Kate is rarely seen without it.
The experts continued: “Kate’s engagement ring is incredibly famous, known for sparking a huge increase in sales of sapphire engagement rings back in 2010.
“It features a 12-carat oval sapphire set in 18k white gold, surrounded by 14 solitaire diamonds.”
The eye-catching ring was originally given to Princess Diana by Prince Charles in February 1981.
At the time, it reportedly cost Prince Charles £28,000 to purchase and the jewel was bought from the former Crown Jeweller.
Since the piece was given to Kate, it has soared in value which the experts suggested could have much to do with the sentimental value of the piece and its royal links.
“Created by Garrard & Co, the former Crown Jeweller, it is now valued at around £300,000,” they continued.
“However, much of its value is sentimental: this engagement ring was passed down from Princess Diana, Prince William’s mother.”
