James Constantinou, founder of Prestige Pawnbrokers and star of Channel 4’s Posh Pawn, said: âSophie, The Countess of Wessex – married to Edward, Earl of Wessex – is a member of the royal family with a collection of valuable jewelry. estimated at over Â£ 3million.
âThe Countess has worn this necklace for many royal appointments.
âIt has the charm of a vintage piece but not only that it has beautifully crafted initials added to hang next to the stone.
“‘E’ for her husband, ‘L’ for her daughter Lady Louise Windsor and an ‘J’ for her son, James Viscount Severn.
“This necklace on a chain has been worn several times before, once with a clam that she has since taken out.”
The necklace has a special connection to her family and she has been spotted wearing it on official engagements.
While Sophie is unlikely to ever part with the necklace, it could be worth a huge amount of money.
Although the gem is subtle, its familial connection would make it popular among many royal devotees.
James told Express.co.uk: âAs with other extraordinary pieces from the Royal Household, the quality is exceptional.
âSometimes you can’t always put a price on a personalized piece of jewelry, especially when the details of the stone in terms of clarity and weight are not known.
“However, it would be fair to say that a coin like this with its royal connection with added historical value could be worth over Â£ 250,000.”
