The Letseng mine in the small Kingdom of Lesotho, South Africa has just uncovered another massive diamond rough: a 198-carat stone, roughly the size of a large strawberry.
A diamond over 100 carats is rare enough – with only about 10 to 15 found each year worldwide – but a rough that is nearly 200 carats is an exceedingly rare find. A stone of this size is expected to yield a polished diamond around 100 carats, or half the weight of the rough it originated from.
Even though the stone’s size is impressive, it is not even close to being the largest ever uncovered from the Letseng mine. In fact, the Letseng mine is well-known for churning out large, quality rough over the years, and has the highest price per carat production of all the mines in the world. Some of the largest include the Lesotho Promise, the 15th largest diamond in the world at 603 carats; the Letseng Legacy at 493 carats, and the Leseli La Letseng at 478 carats which are 18th and 20th largest respectively.
What makes this rough even more valuable is its’ designation of Type IIa, which constitutes less than 2% of all natural diamonds. Type IIa diamonds have no measurable nitrogen impurities, making them chemically pure. This not only gives them exceptional optical transparency, but also a high likelihood of achieving a colorless (D-E-F) grade and a high clarity grade. Officials from Gem Diamonds Ltd, which own the majority stake in the Letseng mine, confirmed this after inspection of the stone noting it as “an exceptional white, high-quality diamond that displays no fluorescence”.
Martin Potts, a London-based mining analyst has estimated the 198 carat stone to fetch somewhere between $12 to $15 million.

We’ve seen many seemingly ordinary items bedazzled into creations of jewelry art: diamond studded shoes by Stuart Weitzman, Victoria’s Secret Fantasy Bras, and even Lady Gaga’s golden wheelchair chariot… but this is the first time expensive jewels are combined with Finnish flora to create a Christmas wreath.
Created by floral designer Pasi Jokinen-Carter, it takes the place as the most expensive wreath ever designed. With 32 diamonds and 16 rubies totalling 138 carats, the creation is priced at $4.6 million. Resting among the elaborate and rare greenery that includes Helleborus flower buds, hand-curled eucalyptus leaves, and blue Hedera berries, the gems add an unmistakable luxurious touch without overwhelming – they create a nice visual contrast with a little pop of color. Twenty-two loose round brilliant diamonds are nestled in the petals of one of the Helleborus flowers, and another cradles a 3.03 carat fancy yellow diamond. The largest gem in the wreath is a 17.49 carat ruby.
“I am passionate about my craft and this recent invitation to create an exclusive wreath, using natural materials and diamonds, has been an exciting and exceptional project,” says Jokinen-Carter. The wreath takes about a week to create, with most of the greenery and flowers sourced from his own backyard. All of the gems can be easily dismantled after the holidays, where they may find new (more permanent!) homes in jewelry pieces.

The New York Museum of Natural History is having an exhibition for the rare 19th century 55 carat diamond that was once part of the Russian Crown Jewels.
The stone is named “Kimberley Diamond” after the Kimberley Mine where it was discovered in South Africa in 1868. It had been cut from a 490 carat crystal. In 1921 it turned into a 70 carat gem and later in 1958 was re-cut and improved for brilliance and proportions. In the re-cutting process the stone lost some weight 14.92 carats. Now weighing 55.09 carats it was valued at $500,000 but is probably worth considerably more now.
Kimberly Diamond has been perfected to a champagne coloured, emerald cut, rectangular flawless diamond. It is about 1.25 inches in length. It has been described as a “cape diamond” which is an Old World term meaning “deep colour.”
In order a diamond to survive the Earth’s surface it has to get there really fast this stone got a ride on magma. Magma starts very deep in the earth and moves towards the surface at 35-40 km/h. During a volcanic eruption the magma creates bubbles like champagne and can reach speeds up to Mach 2 (twice the speed of sound).
Diamonds were first found along rivers where people would look for gold. In the 1870’s lots of diamonds were found at the bottom of rivers and streams in South Africa. They would follow the river upstream and find a grey blue rock which contained a diamond. Now days a gem the size of the Kimberley diamond wouldn’t survive in modern mining techniques it would be crushed in the process.
The diamond will be on display with “Patricia Emerald” and “The Star of India.” Patricia Emerald is a 632 carat 12 sided emerald crystal from Columbia. The Star of India is the world’s largest gem quality blue star sapphire it is 526 carats in weight and is 2 billion years old!
Kimberly Diamond is on loan from Bruce T. Stuart. The stones will be added to the Morgan Memorial hall of Gems and is on display in the NYC museum through to June 2014.

It’s an exciting time for auction houses as many rare stones have been sold in recent months including a 9 carat purple pink diamond and a 3.21 carat blue diamond. These diamonds are just a sample of some of the beautiful gems which have been sold in the past few years. We will recount some of our favourites!
The historic Beau Sancy, one of the world’s most famous diamonds, is 35 carats and internally flawless. This double rose-cut stone was literally owned by kings and pawned by queens. For generations royal families traded the stone back and forth like a valuable baseball card. Sotheby’s auctioned the diamond in May and it was sold for 5 million pounds.
The 33 carat flawless gem formerly known as the Krupp was one of the hottest pieces to sell at Christie’s this past year. The diamond, which sold for over $8.8 million dollars was a featured item from Elizabeth Taylor’s jewelry collection sold in December. Christie’s VP described the piece as “one of the most beautiful gems I have ever seen.”
Last but not least on our list is the Wittlesbach, a legendary 35 carat blue diamond which was bought by Laurence Graff for a record $24.3 million in December 2008. The purchase became very controversial however when the London collected recut the stone soon after acquiring it, losing approximately four carats. The Financial Times wrote a story on the transformation and asked the question “Is this gem vandalism?” Graff remained unfazed from the criticism, boasting that he had improved the stone’s color and clarity. The diamond, now called the Wittelsbach-Graff was exhibited in the Smithsonian’s National Museum of Natural History in 2010 and has continued to dazzle gem aficionados.
