He told Express.co.uk: “Sophie, Countess of Wessex – married to Edward, Earl of Wessex – is a member of the Royal Family with a jewellery collection reportedly worth more than £3million.”
As well as regal tiaras and jewels, Sophie’s collection also features sentimental pieces.
The mother-of-two has a necklace with a sweet link to her husband and children.
Sophie has been seen wearing the pendant on a number of outings over the years.
James continued: “The Countess has worn this necklace on many royal appointments.
“It has the charm of a vintage piece but not only that it has beautifully crafted initials added to hang next to the stone.
“An ‘E’ for her husband, ‘L’ for her daughter Lady Louise Windsor and a ‘J’ for her son, James, Viscount Severn.”
Sophie is the mother of Lady Louise Windsor, 17, and James, Viscount Severn, 13.
As well as having sentimental value, James suggested it is also likely to be worth a small fortune.
He continued: “As with other extraordinary pieces from the royal household the quality is outstanding.
“Sometimes you just can’t always put a price on a personalised piece of jewellery, especially when details on the stone in terms of clarity and weight are not known.
“But it would be fair to say that a piece such as this with its royal connection along with added historic value could be worth in excess of £250,000.”
When Sophie steps out, many royal fans will wait to see what she wears, including her jewellery choices.
Sophie has worn many eye-catching jewels and tiaras since she entered the Royal Family.

The royal line of succession – who outranks who?
The line of succession to the British throne dictates the order in which each member of the Royal Family would ascend to the throne.
It is also seen as a ranking of importance with the head of the line, the Queen, taking the place of ruler.
Older children come before younger children. Traditionally boys came before girls, but this law was changed on 26 March 2015 before the birth of Prince William’s first child.
Incredibly, Catholics are still excluded from the line of succession, as are children born outside of wedlock.
The royals, who usually stick to a strict protocol when appearing in public, often arrive at events in ascending order of importance, with the most important royal arriving last.
Prince Charles, 72, is currently first-in-line to the British throne, followed by Prince William, 38, his oldest son.
Then comes Prince William’s children, George, seven, Charlotte, five, and Louis, two, and they are followed by Prince Harry, 36. Prince Harry is succeeded by his son Archie Harrison, born in May 2019.
