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.

A 6.13-carat fancy intense green diamond set a new per-carat record when it sold at Christie’s on May 27 for a whopping $3.6 million, or $594,510 per carat. The square cushion cut diamond is the center of a rose gold halo style ring, accentuated by natural pink diamonds.
Next to red, green is the rarest of colors found in natural diamonds. For most colored diamonds, the color comes from trace amounts of mineral impurities or extreme pressure conditions while the diamond was forming. The tight chemical structure makes it very difficult for any impurities to enter, which is why colored diamonds are exceedingly rare. Small amounts of boron in the crystal lattice structure of a diamond, for example, will impart a blue hue; same goes with nitrogen for yellow, and hydrogen for violet. What gives a diamond a green hue however, is the presence of natural radiation over millions of years. Because the radiation exposure is an external force rather than internal force (such as mineral impurities and lattice defects), it acts on the surface only. As a result, green diamonds are not green all the way through; the color is concentrated on the outer layers and tends to be weakly saturated. That is why a fancy intense green diamond, especially one of a size like this one, is almost a once-in-a-lifetime find.
This spectacular diamond joins the ranks of other recently sold, record-breaking gems at Christie’s. At their Geneva auction just last month, there were three record-breakers alone. They include ‘The Blue’, a fancy vivid blue pear shaped diamond weighing over 13 carats, a 76.5 carat light pink square-cut diamond that sold for $10.2 million, and the ‘Ocean Dream’ – a 5.5 carat, vivid blue-green diamond that went for $8.8million.

Many showstopping Hearts on Fire pieces have been spotted on the red carpet by actresses from several hit shows including Malin Ackerman (Trophy Wife), Emma Roberts (American Horror Story), Maria Menounos (Extra), and Sarah Rafferty (Suits).

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.

As part of the royal tradition, Kate Middleton is rumored to receive a new mommy gift (or “push present”) for the birth of her first child, Prince George Alexander Louis. It can’t be easy to figure out what to give the mother of the future King of England, but Prince William seems like he has it all figured out.
It is believed that William has commissioned one of the royal jewelers to find a pink diamond that will become the centerpiece of a custom brooch for Kate. He is very involved in the design process, adding sentimental touches to make it that much more special. Due to the scarcity of colored diamonds, in particular high quality ones of a larger size, it may be a while before we see the completed piece. Originally he was contemplating giving her one of his late mother the Princess Diana’s jewels, but decided that he wanted something made just for her. Prince Charles had also presented the late Princess Diana with a gift when William was born – a necklace of diamonds and pearls with a heart-shaped center, and a gold ‘W’ charm for her bracelet.
Fancy colored diamonds have a tradition for the English royal family, especially pink diamonds. Queen Elizabeth II owns one of the most famous pink diamonds in the world: the Williamson Pink, a flawless diamond of over 54 carats rough given to her as a wedding gift in 1947 by Canadian geologist John Williamson. The rough diamond was cut into a 23.6 round brilliant, which the Queen then had set into a diamond flower brooch.

The most beloved First Lady of Argentina was as well-known for her charitable endeavours as she was her glamorous image. Eva Perón (fondly referred to as Evita), the wife of the former Argentinian president Juan Perón was a charming beauty who created her own legacy. She rose from humble beginnings in the rural town of Los Toldos to become a recognized actress before finally meeting her future husband. Soon after, she established the Eva Perón foundation, which focused on helping the common people and provided services such as healthcare, education, and community development nationwide. Being very hands-on, she made many public appearances in the name of her charity and was always impeccably dressed; often in French couture, fur, and elaborate jewels.
One of Perón’s most memorable pieces has surfaced again to the public: the headliner at the upcoming October 15th Sale of Magnificent Jewels by Christie’s, the historic brooch depicting the Argentine flag. Featuring brilliant colorless and yellow diamonds and “mystery-set” blue sapphires, it was a custom designed piece for the first lady by the house of Van Cleef and Arpels. The last time it was seen in public was in April 1998, where it sold at auction for ten times its estimate at an astounding $992,500!
Another iconic piece worn in her 1947 official portrait (which was also used in Argentinian stamps in that era) is a Victorian-era diamond necklace set with eleven oval Burmese rubies. It was also sold at auction in 2003 at an estimate of about $200,000. What is unusual, according to experts, is that the entire necklace remained intact – it was common during the 19th century for important pieces of jewelry to be dismantled and remade.
Very recently, Spanish police have recovered a hoard of stolen jewels estimated at approximately $6 million euros. They organized a sting at the hotel the thieves were staying at in Milan, and they recovered a collection of rings, earrings and a fantastic diamond tiara believed to have been given to Perón by the Dutch royal family.
Much like her life, there is a lot of mystery of origin surrounding Perón’s many jewels, which may also be why some of her most treasured jewelry pieces have wound up at high-end international auctions, fetching record-breaking prices for fascinated jewelry collectors and historic collectors alike.
