With their unspeakable beauty and astounding rarity, jewellery that includes diamonds often sells for mind-blowingly large sums of money. For their size and weight, the most expensive are probably the most valuable items on the planet. The rarest pieces are incredibly hard to come by, and there are even some that are so valuable that their true worth cannot be measured. Here are the top 7 most expensive diamond jewellery ever produced.
#7. Pink diamond
Sotheby’s auctioned a ring in Hong Kong that featured a breathtaking 8.41-carat vivid purple-pink diamond, and it sold for $17.7 million. It was mined by De Beers and actually cut meticulously from a much larger 18-carat diamond before being fitted to its platinum ring. It is mounted and pavé-set with a number of circular-cut diamonds. The beautiful colour is just one amazing aspect of this stone. It’s a Type IIa diamond, chemically the purest of these types of gemstones, and its size, hue and colour saturation are also incredibly rare.
#6. The Winston Blue
This is an extremely valuable platinum ring that features the biggest flawless blue diamond on the planet. It was auctioned by Christie’s back in May 2014 by Harry Winston and sold for $23.8 million. The piece is 13.22 carats, and it was named after the founder of the company by then-CEO Nayla Heyek. The enormous price of the deal actually far exceeded expectations at the time – a surprisingly common occurrence when a bidding war occurs for such rare items.
#5. Pink Emerald-Cut Graff Diamond
The stone in this elegant ring is graded ‘Fancy Intense Pink’ by America’s Gemological Institute. It is a 24.78 carat emerald-cut stone, and was purchased at auction for $46 million by the esteemed Laurence Graff himself. Graff described it as the “most fabulous” stone he had seen in his illustrious career. The combination of colour and purity is perfectly matched by the emerald cut, which is usually only used with white diamonds. This is just one of the rare features that made the ring all the more alluring.
#4. L’Incomparable Necklace
This unbelievably valuable diamond necklace was unveiled by the prestigious Mouawad jewellery company and remains the most valuable piece in this format anywhere in the world. The central gem was discovered purely by chance by a young girl in the Congo, sat in a pile of the diamond mining by-product kimberlite. It is the largest internally flawless diamond in the world – a startling 407.8 carats – and the necklace features a further 102 smaller stones adorning its elegant design. Its value stands at $55 million.
#3. The Pink Star
Stones of this quality rarely become available for purchase. So, when Sotheby’s put a diamond ring adorned with the impressive 59.60 carat Pink Star diamond, the buyers with the deepest pockets were lining up to buy it. The interest in the diamond was so great that the winning bid of $83 million dwarfed the expected price. Unfortunately, the winning bidder was unable to come up with the money in time, so the piece’s value currently stands at $72 million.
#2. The Peacock Brooch by Graff
There’s no-one more pre-eminent in the diamond world than Graff. To illustrate this enviable status, the London-based company created a staggering Peacock brooch which carries a greater value than a private jet. This piece is adorned with 1,305 gemstones and weighs in at 120.81 carats. The vivid blue diamond at its centre tips the scales at more than 20 carats by itself. The piece’s value is around $100 million, so it really wouldn’t be advisable to head out wearing it in public.
#1. The Hope Diamond
This is one of the most infamous pieces of jewellery in the history of the world. It has legendary status not only for its incomprehensible beauty but also for allegedly being cursed. It has existed for centuries, with notable owners including people like King Louis XIV and Harry Winston. Winston actually donated it to the Smithsonian Institute in 1958, and it has remained on display there ever since.
The mesmerising piece, with its 45.52-carat vivid blue diamond, has repeatedly been valued at hundreds of millions of dollars. The Smithsonian, however, claims that due to its rarity, its extremely high profile and its extreme cultural significance, the actual worth of The Hope Diamond is impossible to measure. That makes this remarkable necklace the most valuable piece of diamond jewellery in the world.
The jewellery items in this list are not pieces that you would ever see anyone wearing in public. It is also incredibly rare for any of them to go up for auction. They are one-of-a-kind pieces adorned with diamonds the likes of which have only been discovered a handful of times in history, and their value reflects the remarkable fact that they even exist.
