Trainee Five Months Into His Apprenticeship Is Credited With Discovering the 1,109-Carat Lesedi La Rona Diamond

An eagle-eyed trainee barely five months into his apprenticeship at Lucara’s Karowe mine in Botswana is credited with plucking the 1,109-carat gem-quality diamond — now known as the Lesedi La Rona — from the mining company’s “large diamond recovery” sorting machine. It was the largest rough diamond discovered in 111 years.


“At first I wanted to scream,” Tiroyaone Mathaba told The Telegraph. “Then I said in a low, hoarse voice, ‘God, it’s a diamond! It’s a diamond, it’s a big diamond!’”

The rough stone is the size of a tennis ball and could potentially yield the world’s largest faceted diamond, grander than even “The Great Star of Africa” at 530.20 carats.

Lesedi La Rona, which means “Our Light” in Botswana’s Tswana language, is expected to sell for $70 million or more when it’s offered for sale at Sotheby’s London exactly one week from today. That price would easily break the world record for any gemstone sold at auction. The current record holder is the “Oppenheimer Blue,” a 14.62-carat fancy vivid blue diamond that fetched $57.5 million at Christie’s Geneva in May.

As a trainee, the 27-year-old Mathaba had been responsible for inspecting the rock and sand produced by the mine’s large diamond recovery machines. But, on the morning of Nov. 16, 2015, he was having trouble with the equipment.

“We were experiencing a near blockage,” said the recent graduate of the geology program at the University of Botswana. “I was having to work quite hard.”

Then, he spotted something shiny in his sorting tray. Was it a strange rock, or an unfathomable, mammoth-sized diamond?

Lucara geologists confirmed that Mathaba’s find was the second biggest diamond ever recovered. Only the 3,106-carat Cullinan, unearthed in South Africa in 1905, was larger.


Based on the cleavage faces and sculpted surfaces of the Lesedi La Rona, Lucara experts believe the rough diamond had been much larger. In fact, some of the adjacent pieces have been recovered and matched to the larger stone.

One of the reasons why extremely large diamonds are so rare is because the stones undergo tremendous stress in the mining and sorting process. Although diamonds are the world’s hardest material, they can fracture.

Lucara’s new Tomra large diamond recovery machine, which utilizes X-ray transmission sensors, is designed to identify and isolate potentially large diamonds before they can be damaged. Only one day after Mathaba’s discovery, two other massive diamonds — weighing 813 and 374 carats — also were found.

Despite the $70-million-plus price that Lesedi La Rona is likely to fetch, Mathaba did not earn a special bonus for finding the stone. Instead, each of the 804 people working a Lucara enjoyed bonuses related to the huge windfall. Mothaba has since become a permanent member of the Lucara staff.

Mathaba explained to The Telegraph why he finds his job so exciting: “You get to see diamonds how nature made them – the octahedron shapes, the cubes – before humans touched them.”

Mom Reunited With Her Engagement Ring Six Weeks After Tike Flushes It Down the Toilet

City worker Jose Cervantes called it a “one in a million shot,” but the thin odds of finding an engagement ring in a sewer system six weeks after it was lost didn’t dissuade him from helping a family in need.


Anna and Ryan Cornish, of Bothell, Wash., had been heartbroken over the loss of Anna’s double-halo-style diamond engagement ring — a precious keepsake their 4-year-old son, Landon, had flushed down the toilet during bath time.


Despite the admirable efforts of their plumber — who put cameras in the waste pipes — the ring was nowhere to be found.


But, then by chance, Ryan noticed a truck from the City of Bothell Public Works in his neighborhood. He approached sewer maintenance worker Cervantes and asked if he could help.

Normally, retrieving jewelry in the sewer is a fruitless endeavor. But Cervantes knew of a quirk in the local sewer system that could make all the difference.

“Where [Ryan] lives there’s actually what’s called a belly in a pipe, a settled out piece of pipe,” Cervantes told a Global News affiliate. “It’s a little lower, so solids end up getting in there.”


After getting the thumbs-up from his supervisors, Cervantes and his team returned the next day to suck up the sewage from the depression in the pipe. They dumped the material out of their truck and carefully hosed it down. Emerging from the stinky mess was Anna’s ring.

“It was shocking, amazing,” Cervantes said. “We got the ring. Holy cow, it’s a one in a million shot.”

Ryan was excited when he found out the ring was recovered, but decided to keep the good news from Anna until it could be presented in the proper way.

First, he brought the ring to a local jeweler for a professional and thorough cleaning. Then he placed it in a ring box so a very special person could make the presentation…

“Mom, I’m so sorry. Will you please forgive me?” little Landon said as he handed the ring box to Anna.

“Then he opened the box with the ring inside,” recounted Anna. “I just felt speechless; tears started coming down my eyes.”

Ryan and Anna couldn’t be more grateful to the City of Bothell Public Works crew, who went above and beyond the call of duty. Anna plans to hand the ring down to her daughter, who is now three years old.

Many years from now they’ll have quite a tale to tell.

Amateur Treasure Hunters Unearth Trove of 1,100-Year-Old Viking Bangles in Denmark

Three amateur treasure hunters, who call themselves “Team Rainbow Power,” unearthed the largest trove of Viking gold ever found in Denmark.


Working with metal detectors in a field in Jutland, the team discovered seven bangles — six gold and one silver — dating back to the year 900. The combined weight of the jewelry, nearly all of which remained in pristine condition despite being buried for more than 1,100 years, is 900 grams (about 2 pounds). Only the silver bangle has tarnished.


“We really felt like we had found the pot of gold at the end of the rainbow when we found the first bracelet, but when others then appeared it was almost unreal,” noted Team Rainbow Power member Marie Aagaard Larsen.


Larsen revealed that her team, which includes Poul Nørgaard Pedersen and Kristen Dreiøe, had been working in the field barely 10 minutes when the metal detectors indicated that there was treasure underfoot.

After finding the third of seven bracelets, Team Rainbow Power sought the assistance of Lars Grundvad from the Sønderskov Museum.

The field in Jutland had been of interest to archaeologists at the museum because a Viking gold chain had been discovered there more than 100 years ago.

“At the museum, we had talked about how interesting it could be to check out the area with metal detectors because there was a 67-gram gold chain found there back in 1911,” Grundvad said. “But I would have never in my wildest fantasies believed that amateur archaeologists could uncover seven bracelets from the Viking Age.”


Two of the gold bracelets discovered by Team Rainbow Power are crafted in the Jelling style, which is associated with the Viking elite. Peter Pentz, a Viking expert at the National Museum, believes the bracelets may have been used by a Viking leader to form alliances or to reward his faithful followers.


The Viking social classes of this era were divided into the noble “jarls,” the middle class “karls” and the slave class “thralls.”

“To find just one of these rings is huge, so it is something special to find seven,” said Pentz. “The Viking Age is actually the ‘silver age’ when it comes to hoards. The vast majority of them contain only silver. If there is gold, it is always a small part, not like here, the majority.”

Why the jewelry was buried is a more difficult mystery to unravel. Perhaps they were buried in a ritual, or hidden by someone who failed to retrieve them, say the archaeologists.

The Sønderskov Museum, which is only 13 miles from the discovery site, will put the seven bracelets on display before shipping them 160 miles east to the National Museum in Copenhagen for further study. Team Rainbow Power will be compensated for their find, although the exact amount has not been disclosed.

Music Friday: Silver Earrings, Gold Bracelet Play Key Roles in the Hauntingly Beautiful ‘All I Left Behind’

Welcome to Music Friday when we bring you great songs with jewelry, gemstones or precious metals in the title or lyrics. Today, we feature the hauntingly beautiful harmonies of Linda Ronstadt and Emmylou Harris in their 1999 duet “All I Left Behind.”


A song about a woman who unselfishly puts her life on hold to go on the road with her lover, “All I Left Behind” recounts the items she lost along the way, which include her silver earrings and a her dad’s gold bracelet. In the end, she loses her lover, as well.

They sing, “Silver earrings in Wichita / Beaded moccasins in Tonopah / But I had you so, I just let them go.”

In a later verse, the story of a cherished keepsake is told: “And the gold bracelet with my father’s name inscribed / On the back by the one who loved him all her life / The way I too could have loved you.”

Written by Harris with Kate and Anna McGarrigle, “All I Left Behind” appeared as the 12th track on Western Wall: The Tucson Sessions, a Ronstadt/Harris duet album that included songs written by a virtual Who’s Who of the music industry. Among those receiving writing credits on the album were Jackson Brown, Rosanne Cash, Sinéad O’Connor and Bruce Springsteen. Singing background vocals and playing the harmonica on the album was none other than Neil Young.


“It took more than 25 years, two divergent careers and plenty of false starts, near-misses and might-have-beens, but Linda Ronstadt and Emmylou Harris have finally made an album together,” wrote Bill DeYoung for Goldmine magazine back in 1999.

“I believe that there’s a poetic thread that holds [the songs] together,” Harris told Goldmine. “I think they all deal with very deep issues about life and love and longing and loss. For me, an album has to be a string of pearls, but they’re all slightly different. They’re not perfectly matched pearls.”

The album — featuring the velvety alto of Ronstadt and songbird soprano of Harris — earned critical acclaim, hitting #6 on the Billboard Country albums chart while earning several Grammy nominations.

Ronstadt, who will turn 70 next month, is a 2014 inductee into the Rock and Roll Hall of Fame. She has released more than 30 studio albums and charted 38 Billboard Hot 100 singles, including “You’re No Good,” which reached #1. She has earned 11 Grammy Awards, three American Music Awards, two Academy of Country Music awards, an Emmy Award, a Tony nomination and a Golden Globe nomination.

The 69-year-old Emmylou Harris also boasts a long and stellar career, during which she accumulated 13 Grammy awards and 39 Grammy nominations. She has collaborated with the industry’s biggest names, including Gram Parsons, Bob Dylan, John Denver, Dolly Parton, Roy Orbison, Cyndi Lauper and Ryan Adams. Her most recent collaboration with Rodney Crowell earned the duo a 2016 Americana Music Association Award nomination in the category of Duo/Group of the Year.

We hope you enjoy the audio track of Ronstadt and Harris performing “All I Left Behind.” The lyrics are below if you’d like to sing along…

“All I Left Behind”
Written by Emmylou Harris, Kate McGarrigle and Anna McGarrigle. Performed by Linda Ronstadt and Emmylou Harris.

All I left behind should come as no surprise
To me since I fell through the black hole of your eyes
Only little things inconsequential I could say
Of all I left behind with you along the lost highway

Silver earrings in Wichita
Beaded moccasins in Tonopah
But I had you so, I just let them go

The flannel shirt I wore to keep me from the cold
When we drove from Boston all the way to Buffalo
The leather boots I bought, so many miles ago
I took them off to follow you into the Ohio

Never did my armor feel so thin
Silk was all I had between me and your skin
Like Waterloo, I lost that too

And the gold bracelet with my father’s name inscribed
On the back by the one who loved him all her life
The way I, too, could have loved you

The Spanish shawl, I put across the broken shade
Of the lamp that lit the room that last night near Coeur d’Alene
Only little things inconsequential I could say
Of all I left behind with you along the lost highway

Of all I left behind, all I left behind

Egypt’s Ancient Gold Mines Offer Clues on Where Untapped Reserves May Lie

To the ancient Egyptians, gold was divine. The gods, they believed, had skin of gold, bones of silver and hair of lapis lazuli. The Turin Papyrus Map, which dates to 1160 BC, affirms the location of 1,300 gold mines, at least 100 of which have been rediscovered and explored in the desert valleys east of the Nile.


Today, armed with clues from the ancient mines, modern prospectors are trying to locate untapped Egyptian reserves said to be worth hundreds of billions of dollars.

When English Egyptologist Howard Carter discovered the 3,300-year-old tomb of King Tutankhamun in 1925, he was impressed by a sarcophagus that held not one, but three, coffins. The outer two were crafted in wood, covered in gold and adorned with many semiprecious stones. The inner coffin was made of solid gold.


The king’s death mask — constructed of two sheets of hammered gold and weighing 22.5 pounds — is considered one of the masterpieces of Egyptian art. In all, Tutankhamun’s tomb was filled with more than 500 items, many made of pure gold.

Despite their reverence of gold, the precious metal held no monetary importance in ancient Egyptian commerce. Salaries were paid in goods, and trade was done with barter. Gold maintained a vital role in religious ceremonies, adorning royal jewelry, artifacts and chariots.

Contemporary treasure hunters are betting that the ancient miners — lacking modern tools and know-how — left plenty of gold behind. Those miners rarely dug down more than 20 or 30 meters.

“We are looking where they had mined gold before,” Mark Campbell, the chief executive of Canada-based Alexander Nubia, told CNN. “Using modern mining techniques and technology, we hope to recover a lot of the gold that [the Roman and Egyptian civilizations] missed, because they were unable to mine it and process it.”

(Nub, which appears in the exploration company’s name, is the Egyptian term for gold.)

Mining for gold in the Egyptian desert is risky business due to the extraordinary expense of modern extraction techniques. Campbell estimated the investment would be “somewhere in the order of 500 million to a billion dollars.”

24.18-Carat ‘Cullinan Dream’ Is the Latest Record Breaker Sourced at the Legendary South African Mine

Over the past 113 years, a single mine in South Africa has been the most prolific source of the world’s largest and finest-quality diamonds. On June 9, the 24.18-carat “Cullinan Dream” — named after the mine that famously yielded the 3,106.75-carat Cullinan — broke the record for the highest price ever achieved for a fancy intense blue diamond. It was the largest diamond of that color classification to be offered at auction.


Bidders at Christie’s Magnificent Jewels auction in New York watched the hammer go down at $25.4 million, which was in the mid range of the auction house’s pre-sale estimate of $23 million to $29 million.


Discovered at Petra Diamond’s Cullinan mine in 2014, the rough diamond that produced the Cullinan Dream weighed 122.52 carats.

From that rough stone, a master gem cutter eventually delivered four notably sized blue diamonds: a cushion-cut gem of 7.00 carats, a radiant-cut gem of 10.30 carats, a pear-shaped gem of 11.30 carats, and finally, the Cullinan Dream, a cut-cornered rectangular mixed-cut gem of 24.18 carats.


Set in a ring, the Cullinan Dream is flanked by tapered baguettes in a platinum mounting inscribed “Cullinan Dream.” The baguettes have a total weight of 2.36 carats.

Petra Diamonds had sold the 122.52-carat rough blue diamond into a cutting and polishing partnership in 2014 for $23.5 million and maintained a 15% stake in the proceeds from the Cullinan Dream after it was sold at auction, minus expenses.

While setting an auction record in the “fancy intense blue” category, the Cullinan Dream’s selling price was less than half the amount earned by the much smaller “Oppenheimer Blue,” which yielded $57.5 million at Christie’s Geneva in mid-May. The 14.62-carat Oppenheimer Blue was able to set a new world record for any jewel sold at auction because it carried the top color grade of “fancy vivid blue,” the top purity rating of Type IIa, and the near-perfect clarity rating of VVS1. The Cullinan Dream, by comparison, had a clarity of VS2 and a purity rating of Type IIb.

The Cullinan Dream represents the latest generation of super-large, super-fine diamonds to be sourced at the Cullinan mine. Since production started in 1903, the mine has delivered 750 stones weighing more than 100 carats, 130 stones weighing more than 200 carats, and more than a quarter of all diamonds in existence weighing more than 400 carats. The mine is expected to be productive for the next 50 years.

Denver Broncos’ Massive Super Bowl 50 Championship Rings Boast 194 Diamonds Weighing 5.05 Carats

The champion Denver Broncos received their Super Bowl rings in a private ceremony held at Mile High Stadium on Sunday night. Adorned with 194 diamonds and a flourish of orange sapphires, the two-tone 10-karat gold rings commemorate in high style the team’s 24-10 impressive victory over the Carolina Panthers in Super Bowl 50.


Photos taken by the players and posted to Twitter confirm the huge proportions of the rings, which boast a diamond total weight of 5.05 carats and seem to dwarf the massive fingers of the most imposing athletes on the planet.


The rings were delivered to the stadium under high security in padlocked boxes, one for each player, coach, front-office member and support staff. Each box was emblazoned with the logo of Super Bowl 50.


As with all Super Bowl rings, the Broncos’ treasure is teeming with symbolism. The ring’s face features the Super Bowl 50 logo and the team’s three Lombardi Trophies placed above the Denver Broncos logo on a field of pavé-set diamonds. The trophies are created from marquise-cut stones, tapered baguettes and pave-set stones, and represent the franchise’s three Super Bowl wins.

The Bronco mane is designed in three waves of bright orange sapphires, while the head features pavé-set diamonds. The Bronco’s eye is a round orange sapphire. The words “WORLD CHAMPIONS” adorn the top and bottom edges in raised gold letters.


The left side of the ring features the player’s name above an image of a crown, which is a nod to the crown featured on past Broncos Super Bowl Championship Rings. The crown’s three stripes represent the three Super Bowl titles. Eight round diamonds adorn the top of the crown and represent the team’s eight AFC Championships. The player’s number sits below the crown and is created from round pavé-set diamonds.

The right side features the words DENVER BRONCOS arched above an image of the Lombardi Trophy and the year 2015. The trophy is created from marquise-cut and pavé-set diamonds and is surrounded by a 10-karat yellow gold banner inscribed with the words “THIS ONE’S FOR PAT” in honor of Denver Broncos Owner Pat Bowlen, who is suffering from Alzheimer’s disease.


Both sides of the ring are set with 28 diamonds, for a total of 56, marking the 56-year history of the Denver Broncos. The front and back edges each have 15 stones representing the 15 Divisional titles the Broncos have won and the team’s 15 regular season and playoff wins in 2015-16.

The inside of the ring features the Super Bowl 50 logo and the Broncos logo above the Super Bowl date of 02.07.16. The scores of the three playoff games are listed next to the logos of the teams the Broncos defeated.

On hand to help the team celebrate were legendary players who were on past Super Bowl teams. Terrell Davis and Rod Smith were entrusted with the task of handing out the keys that opened the padlocked gift boxes.

Neither the ring manufacturer, Jostens, nor the Broncos’ management would disclose the value of this year’s rings. What we do know is that the Super Bowl XLIX rings of the New England Patriots were valued at $36,500.

Missouri Sheriff Saves ‘Perfect’ Engagement Ring From Muddy Demise

Missouri bride-to-be Linda Huffman says the 1-carat solitaire engagement ring she got on Valentine’s Day from fiancé Steve Kozlowski is “the only thing I’ve had in my life that was perfect.”


But after a swimming mishap at a local creek on Memorial Day, she was sure her perfect ring was lost forever.


Huffman had been spending a glorious day with her family and friends at Dry Fork Creek, about 100 miles southwest of St. Louis, when she attempted to climb upon a huge boulder that jutted from the shore out into water. But she lost her footing, fell back, banged her hand against the limestone and the ring went flying.

“I was for sure that it was gone,” Huffman told

The newly engaged couple, with the help of their loved ones, attempted to use swim goggles and snorkel gear to find the ring, but with only 3 inches of visibility there was little hope of locating it. Then a storm broke out and the couple had to abandon the search.


Knowing how much the ring meant to his fiancée, Kozlowski called for expert assistance.

He recruited Maries County Sheriff’s Deputy Dennis Jasper and Sheriff Chris Heitman, both of whom are members of the Mid-Missouri Sheriffs’ Dive Team.


“It isn’t something we typically do,” Heitman told, “but for something as important as an engagement ring, we’re there,” he said.


Jasper compared the prospects of locating the ring to “finding a needle in a haystack.”

On the first day of the search, Heitman did his best to scour the bottom of the muddy creek but had to give up after depleting his air supply. Undaunted, he was back on Day 2 to try again.

Based on Huffman’s more precise description of how she fell off the rock, Heitman guessed where the ring may have landed and worked a new area. Again, the search was proving unsuccessful.

“I was exhausted. I was almost out of air in my tank,” Heitman told

But then he saw the ring and plucked it out of the mud.

Heitman was so excited when he came up out of the water that he looked Kozlowski straight in the eyes and joked, “Will you marry me.” Then Kozlowski started screaming.

Huffman and Kozlowski, who had dated for 17 years before getting engaged, couldn’t be more appreciative of the extraordinary recovery efforts.

“He’s my angel,” Huffman told “It’s absolutely the most amazing thing anybody ever did for me.”

With the ring properly resized, the couple is planning an April 2017 wedding with Dry Fork Creek as the scenic backdrop. It was the site of their first date and, now, a miraculous ring recovery.

“We got a story to tell the grandkids,” she said.
