Camilla Parker Bowles: Prince Charles’ wife wears royal jewellery worth £27million
Camilla Parker Bowles, 70, is a fan of statement jewellery if her fashion choices are anything to go by. When it comes to attending important royal events, the Duchess of Cornwall is often seen wearing some of the most dazzling pieces from the Queen’s collection and her own.
Grant Mobley, a gemologist and Director at Pluczenik, one of the world’s leading diamantaires has valued some of her favourite pieces, and they are worth an enormous sum of money.

Camilla’s engagement ring
Grant said: “Camilla’s engagement ring from Charles belonged to the Queen Mother.
“I would imagine the approximate five carat large emerald cut centre diamond flanked by six baguettes in an art deco pattern and platinum setting would be worth in or around $225,000 USD (around £166,000).”
Is Camilla or Kate Middleton’s engagement ring worth more?

The Greville Tiara
The Greville Tiara was made by Boucheron for the Hon. Mrs. Greville (a well-known society maven) in 1921 out of stones salvaged from another tiara before being given to the Queen.
Grant said: “Since there are hundreds of stones in this tiara in a range of sizes dating back several decades, it is almost impossible to estimate a value.
“I would be inclined to say that thanks to the history of this piece and quantity of diamonds it is priceless, but if a price tag had to be put on it, judging by photos alone, it looks to be approximately 200 carats in total with stones up to five carats each, therefore I would estimate a value of $5 million USD (£3.7m).”

The Greville Festoon Necklace
The Greville Festoon Necklace from Cartier, which was a part of Mrs. Greville’s famous jewellery bequest to the Queen Mother consists of five strands of diamonds.
Grant said: “Cartier’s luxurious pieces are known in particular for their Art deco designs, which are very appropriate for a brand that has been selling jewellery since 1847.
“What’s spectacular about the Art Deco designs is that even though they were created decades and sometimes even centuries ago, they have an uncanny way of representing a period in history and carrying through to today fashioning a modern, yet vintage look.
“Because of the many gorgeous diamonds, this is an incredibly unique and valuable piece. In total, the necklace appears to be around 250 to 300 carats with stones as big as five carats, going by that, the value would be around $6m USD (£4.4m).”

This necklace has 25 round white diamonds, each up to over 11 carats along with a pear shape dangling diamond on the bottom, which alone weighs over 22 carats.
Grant said: This exquisite piece is made from old mine cut diamonds, a style of cutting which has been used since the end of the 17th century, giving the piece an antique look.
“The cut of the diamonds makes this piece incredibly unique since they reflect differently from today’s brilliant cut diamonds. There are countless, modern, brilliant diamonds in circulation, but only a handful of old mine diamonds available.
“The intrinsic value of this piece with no history taken into account would be upwards of $16m USD (£12m), but with the extensive history that comes with diamonds, especially those that belong to the Royal family, the cut of the diamonds and the fact that diamonds appreciate in value over time, means that it is incredibly hard to put a price on this precious piece and it could actually be worth a lot more.”

The Diamond Serpent Necklace
This necklace was given to Camilla in the year before her wedding.
Grant said: “With round diamonds as large as two carats and tapering down in both directions, this magnificent piece would have a price tag of up to $400,000 USD (around £290,000).”
However, Grant added that it is incredibly difficult to value these pieces. He said: “It is very challenging to estimate a value for all these incredible pieces due to their diamond composition, the cut of the diamonds and their rich history.
“Diamonds hold or increase in value, especially if they become part of a famous collection, like the Royal collection. The Royal family has always made sure that they have invested in valuable pieces of jewellery and this tradition has not changed.
“Laboratory grown diamonds have been introduced to the market in the last few years, but because they have no inherent value it is highly unlikely that we would ever see a member of the royal family fashioning a piece made from laboratory-grown diamonds.”
