Rio Tinto's Argyle Mine in Western Australia — the world's most prolific diamond mine and primary source for pink, red and blue diamonds — is nearly tapped out. The mine is expected to cease operations in 2021 after a 38-year run that has produced more than 800 million carats of rough diamonds.

While the bulk of Argyle's yearly output is brown in color, a minute segment of the production represents fancy-color diamonds so rare and so valuable that only 16 people in the world are permitted to touch them.

According to a recent article in The Western Australian, Rio Tinto has 50,000 employees worldwide and not even its London-based CEO, Jean-Sebastien Jacques, is allowed handle the 58 diamonds that make up the 2017 Argyle Pink Diamonds Tender.

The 2017 Tender is currently on a multi-city tour that started in Perth, traveled to Hong Kong and will end in New York. At each stop, top buyers are being invited to view the collection and put their secret bids into sealed envelopes. Bidding ends on October 11 and winners will be announced shortly thereafter.

The headliner of the 2017 Tender is a fancy red diamond called the Argyle Everglow. The 2.11-carat, VS2-clarity, radiant-cut diamond was given this name because it seemed to possess an inner glow. The magnificent diamond, which could sell for upwards of $10 million, was cut from a 4.38-carat rough diamond discovered in the fall of 2016. It is the first 2-carat-plus fancy red diamond ever offered by Rio Tinto.

Red diamonds are so rare that in the 33-year history of the Argyle Pink Diamonds Tender there have been fewer than 20 carats of fancy red certified diamonds sold.

The collection includes five “hero” diamonds selected for their unique beauty and named by Rio Tinto to ensure there is a permanent record of their contribution to the history of the world’s most important diamonds:

• Argyle Everglow™ — 2.11-carat radiant-cut fancy red diamond
• Argyle Isla™ — 1.14 carat radiant-cut fancy red diamond
• Argyle Avaline™ — 2.42-carat cushion-cut fancy purple-pink diamond
• Argyle Kalina™ — 1.50-carat oval-cut fancy deep pink diamond
• Argyle Liberté™ — 0.91-carat radiant-cut fancy deep gray-violet diamond

Rio Tinto's Argyle mine is currently the largest diamond producer in the world by volume and accounts for 90% of the world's pink diamonds. Once shuttered, the world's annual supply of fancy-colored pinks, reds and blues are expected to diminish, forcing prices sky high.

If the Argyle Everglow earns a $10 million bid, it will set a record for the highest price ever paid per carat for a gemstone. The current record is held by the 12.03-carat Blue Moon of Josephine, which sold for $48.4 million, or a bit over $4 million per carat.

It is believed that red diamonds get their rich color from a molecular structure distortion that occurs as the jewel forms in the earth’s crust. By contrast, other colored diamonds get their color from trace elements, such as boron (yielding a blue diamond) or nitrogen (yielding yellow), in their chemical composition.

Welcome to Music Friday when we often bring you inspirational songs with jewelry, gemstones or precious metals in the title or lyrics. Today, Christian hip-hop recording artist TobyMac collaborates with American Idol contestant Hollyn on "Lights Shine Bright," an uplifting tune about making the world a better place.

In "Lights Shine Bright," TobyMac wants to "make this third rock glow" by magnifying God's light with the brilliance and intensity that only a perfectly cut diamond could achieve.

He sings, "I wanna magnify Your light / I wanna reflect the sun / Cut like precious diamonds / With the colors by the millions."

Written by David Garcia, Truett McKeehan and Solomon Olds, "Lights Shine Bright" was the fourth track from TobyMac's 2015 release, ***THIS IS NOT A TEST***. The album zoomed to #4 on the Billboard 200 and scored a Grammy Award for Best Contemporary Christian Music Album in 2016.

TobyMac's official website explains that the songs on the album provide an essential reminder that "we only have one shot at life."

“What hits me now more than ever is that you really don’t get a practice run at life,” he explained. “This is it. In my friendships, raising my children, loving my wife, loving people, performing with my band and stepping on stage at arenas, I want to make every moment count.”

"Lights Shine Bright" features the vocal stylings of music-industry newcomer Hollyn, who is best known for her successful run on American Idol during Season 12. A native of Waverly, Ohio, the 20-year-old, whose birth name is Holly Marie Miller, released an album this year called One-Way Conversations.

Born Kevin Michael McKeehan in Fairfax, Va., in 1964, TobyMac has sold more than 11 million records and has earned seven Grammy Awards. He first came on the Christian music scene in 1987 as a member of the vocal trio DC Talk. In 2000, the group announced a hiatus and TobyMac embarked on what has been a successful solo career.

Please check out the official video of "Lights Shine Bright." The lyrics are below if you'd like to sing along...

"Lights Shine Bright"
Written by David Garcia, McKeehan, Truett McKeehan and Solomon Olds. Performed by TobyMac, featuring Hollyn.

Lights shine bright everywhere we go
Music for the people to illuminate the soul
Lights shine bright everywhere we go
Music for the people, makin’ music for the people

I wanna magnify Your light
I wanna reflect the sun
Cut like precious diamonds
With the colors by the millions
This is the only world we know
And for now this rental’s our home
If we gonna be a reflection
Gotta make this third rock glow
(Just so you know…)

Lights shine bright everywhere we go
Music for the people to illuminate the soul
Lights shine bright everywhere we go
Music for the people, makin’ music for the people

Lights shine bright everywhere we go
Music for the people to illuminate the soul
Lights shine bright everywhere we go
Music for the people
Jesus music for the people

Everywhere we go
Lights shine bright, lights shine bright
Everywhere we go
Lights shine bright, lights shine bright

Lights in the city might be more than pretty, pretty
That freaky shine might be more than meets the eye
Anytime you see that sparkle in the dark you might look deeper, deeper
It might be more than simply theatre

Yo, that smile might be joy that’s connected to the spirit
The spirit might be contagious if you dare, you dare come near it
I remember, can’t forget, peace that you can’t second guess
Sparkle as the light reflects we writin’ pay it forward checks

Lights shine bright everywhere we go
Music for the people to illuminate the soul
Lights shine bright everywhere we go
Music for the people, makin’ music for the people

Lights shine bright everywhere we go
Music for the people to illuminate the soul
Lights shine bright everywhere we go
Music for the people
Jesus music for the people

Everywhere we go
Lights shine bright, lights shine bright
Everywhere we go
Lights shine bright, lights shine bright

The lights in the city shine bright
The lights in the city shine bright
So let your heart light shine tonight

Lights shine bright everywhere we go
Music for the people to illuminate the soul
Lights shine bright everywhere we go
Music for the people, makin’ music for the people

Lights shine bright everywhere we go
Music for the people to illuminate the soul
Lights shine bright everywhere we go
Music for the people
Jesus music for the people

Everywhere we go
Lights shine bright, lights shine bright
Everywhere we go
Lights shine bright, lights shine bright...

Ancient Egyptians were captivated by gold. They considered gold "the skin of the gods" and associated it with eternity. They wore elaborate jewelry to enhance their beauty, indicate their social status and to express their spirituality. Egypt's connection with gold dates back more than 5,000 years, and the goldsmiths who worked with the precious metal were held in the highest regard.

On Saturday, Dr. Khaled El-Enany of the Egyptian Antiquities Ministry announced the discovery of a 3,500-year-old tomb built for a prominent goldsmith named Amenemhat and his wife, Amenhotep. The tomb is located near the Nile River at the cemetery of Dra' Abu el-Naga in Luxor, an ancient city often characterized as the "world's greatest open-air museum."

Hieroglyphic inscriptions found inside the tomb affirmed the name of its owner and his profession. Buried with their parents were two adult children.

Archaeologists, led by Dr. Mostafa Waziri, Director General of Luxor, used a ladder to descend 20 feet into the tomb. The entrance led to a square chamber, where a partly damaged sandstone statue depicted Amenemhat sitting in a high-back chair next to his wife, who is wearing a long dress and a wig. Between them, in a smaller scale, is a figure of one of their sons.

Objects, such as gilded coffins, vessels, death masks, obelisks, statues — and jewelry — were often placed in Egyptian tombs to accompany the deceased to the afterlife. Amenemhat's tomb included jewelry, but the Egyptian Antiquities Ministry has yet to release photos of these items.

Dr. El-Enany explained that the distinguished couple and their two sons lived in the 15th century B.C. Archaeologists believe that the tomb was also reused during the 11th and 10th centuries B.C.

Ancient Egyptians' affinity for gold was bolstered by the vast natural resources that were being mined in Egypt's Eastern Desert and Nubia ("nub" is the Egyptian word for gold).

With his hands sweating and his heart thumping, Seth Dixon became an accidental media star early this week when he fumbled a diamond engagement ring through the planks of a wooden footbridge in Kansas City. The 26-second video of a marriage proposal gone horribly wrong has caught the attention of major media outlets from coast to coast and around the globe.

The Kansas City resident had planned to surprise his girlfriend, Ruth Marie Salas, by popping the question on Saturday at picturesque Loose Park.

"I knew I wanted to propose [at Loose Park] just because it's kind of our spot," Dixon told local television station KSHB. "We just kind of fell in love with the park and the beauty of it."

With a friend documenting the momentous event on her cell phone, Dixon went down on one knee at the crest of the bridge. The anxious suitor popped open the black ring box, but couldn't keep a grip on the engagement ring. Dixon and Salas looked on in disbelief as the $4,000 diamond ring bounced twice on the bridge, disappeared through a gap between the boards and splashed into the pond below. Circled in the photo, above, is the ring just before it falls through the bridge.

"It ping-ponged through the crack and I hear it plop in the water," Salas told KSHB. "I didn't know what else to think but, 'Oh my goodness.'"

Dixon, Salas and the friend made an attempt to rescue the ring, but the poor visibility and deep silt made the search very difficult.

They returned Sunday morning with a metal detector enthusiast, who came up empty because the water was too deep.

At 11 a.m. the couple attended a church service and told the congregants from Lifegate Church in Independence about their plight. By 3 p.m., more than 25 friends from the church had donned goggles and swimming gear to join in the search. Fellow parishioner and professional wedding photographer Staci Dabney captured the water-bound excitement on Sunday.

Despite the outpouring of love and support from the community, the ring could not be found.

On Monday, a GoFundMe page was established on behalf of the couple. The funds were earmarked for a replacement ring, but by Tuesday afternoon, the campaign was marked completed after only $261 had been raised. It looks as if the viral video will be generating enough cash for the couple to purchase a new ring. Major media outlets will be paying a fee to use the video. As of today, the video was still available to view on the Facebook page of Staci Dabney's Photography. Click this link.

The internet stars, who had been dating for four years, plan to wed October 21.

Wildly divergent hues unbounded by traditional guidelines, seasonal borders or gender norms are the stars of Pantone's Fashion Color Trend Report for the spring of 2018. The "untypical" palette reflects the top 12 colors seen on the catwalks during NY Fashion Week, which concludes tomorrow in Manhattan.

Meadowlark / Cherry Tomato / Little Boy Blue / Chili Oil

Pantone, the global color authority, publishes its report to give consumers and retailers a sneak peek at the color stories that will emerge in all areas of design and fashion in the coming year.

Among 2018's "uplifting shades" and "feel-good tones" are Meadowlark, a confident and outgoing bright yellow, and Cherry Tomato, a tempestuous orangey red. Other favorites include Little Boy Blue, reminiscent of a clear blue sky; Chili Oil, an earthy brown-based red; Pink Lavender, a soft and romantic violet rose; and Arcadia, a cooler, cleaner take on green.

Pink Lavender / Blooming Dahlia / Arcadia / Ultra Violet

Emperador / Almost Mauve / Spring Crocus / Lime Punch

“The color palette showcases an appreciation for the complexity and distinctiveness of color and the expression of it, which is something that evolves and can be played with,” said Leatrice Eiseman, Executive Director of the Pantone Color Institute. “Consumers need more variety, and this expanded palette embraces the lack of gender and seasonal borders we are seeing within the fashion industry.”

Sailor Blue / Harbor Mist / Warm Sand / Coconut Milk

In additional to the 12 "call-out shades," Pantone also revealed four "seasonal classics." These more subdued tones provide the mainstay of the wardrobe and the foundational core upon which consumers can start building their own personal style. Seasonal classics include the dark navy Sailor Blue, dove grey Harbor Mist, neutral Warm Sand and off-white Coconut Milk.

In early December, we will announce Pantone's Color of the Year for 2018. Previous winners have included Greenery (2017), Rose Quartz/Serenity Blue (co-winners for 2016), Marsala (2015), Radiant Orchid (2014), Emerald (2013) and Tangerine Tango (2012).

Months ago, Tulsa native Russ Dugger scheduled a romantic vacation to scenic Key West, Fla., where he planned to surprise his girlfriend, Nadia Kyrylova, with a marriage proposal on the world famous beach. Little did he know that they'd be crossing paths with a Category 4 hurricane.

The couple checked into their Key West hotel last Sunday, and Dugger was all set to pop the question on Wednesday with the assistance of the hotel staff.

But, with Hurricane Irma predicted to make a hard, northward turn from Cuba toward the Florida Keys, hotel officials instructed the couple on Tuesday morning that they had to evacuate before Wednesday at noon.

By Tuesday afternoon, Key West looked like a boarded-up ghost town, but Dugger wasn't going to let a hurricane stand in the way of his proposal. The couple had already survived a tornado together in Tulsa.

Most of the hotel staff had already evacuated, so he would have to go it alone.

In a scene that could only be described as surreal, Dugger proposed to Kyrylova Tuesday afternoon on an impossibly deserted Key West beach.

"Everybody was gone," Dugger told Tulsa's Fox affiliate Fox23.

Kyrylova accepted Dugger's marriage proposal and a diamond engagement ring with a resounding "Yes." But, now the couple had to outrun one of the biggest and most powerful hurricanes to ever make landfall in the U.S.

On Wednesday, they hopped into their rented car and made the four-hour journey to Ft. Lauderdale airport. There, they waited for hours, hoping that their Fort Lauderdale-to-Dallas-to-Tulsa flight would be allowed to take off. By Thursday, they had finally arrived in Dallas, where they spent the night. On early Friday morning, the exhausted, but relieved, couple was greeted by a Fox news crew at the baggage carousel at Tulsa International Airport.

Dugger and Kyrylova will be able to tell future generations that their love was able to overcome two natural disasters — an Oklahoma tornado and a Florida hurricane.

The couple plans to marry in Colorado in 2018.

Welcome to Music Friday when we bring you awesome songs with jewelry, gemstones or precious metals in the lyrics or title. Today, Mark Knopfler scores a "beautiful find" in his 2006 release, "I Dug Up a Diamond."

When taken literally, the song written by Knopfler is about a diamond miner who makes an unbelievable discovery. Metaphorically, "I Dug Up a Diamond" is about a man who's been on a seemingly hopeless search for the love of his life — and then finally finds her.

He sings, "I dug up a diamond / Rare and fine / I dug up a diamond / In a deep dark mine / If only I could cling to / My beautiful find / I dug up a diamond / In a deep dark mine / My gem is special / Beyond all worth / As strong as any metal / Or stone in the earth."

Providing the sweet harmonies for "I Dug Up a Diamond" is country legend Emmylou Harris. The pair had been friends since the late 1980s and decided to collaborate on an album, which they titled All the Roadrunning. Their work earned critical acclaim as the album peaked at #17 on the U.S. Billboard 200 chart.

The 68-year-old Knopfler, who is best known as the frontman for Dire Straits, was born in Glasgow, Scotland, and grew up in Northumberland, England. Both are coal mining regions, so it is likely he drew his "I Dug Up a Diamond" lyrical inspiration from first-hand experiences.

A four-time Grammy Award winner, Knopfler is ranked 27th on Rolling Stone's list of the 100 Greatest Guitarists of All Time. Knopfler and Dire Straits have sold more than 120 million records.

Born in Birmingham, Ala., the 70-year-old Harris is a 13-time Grammy winner and a member of the Country Music Hall of Fame. She's collaborated with some of the music industry's biggest names, including Bob Dylan, Linda Ronstadt, Dolly Parton, Roy Orbison, Willie Nelson and Neil Young.

Please check out the video of Knopfler and Harris performing "I Dug Up A Diamond." The lyrics are below if you'd like to sing along...

"I Dug Up A Diamond"
Written by Mark Knopfler. Performed by Mark Knopfler and Emmylou Harris.

I dug up a diamond
Rare and fine
I dug up a diamond
In a deep dark mine
If only I could cling to
My beautiful find
I dug up a diamond
In a deep dark mine

My gem is special
Beyond all worth
As strong as any metal
Or stone in the earth
Sharp as any razor
Or blade you can buy
Bright as any laser
Or any star in the sky

Maybe once in a lifetime
You'll hold one in your hand
Once in a lifetime
In this land
Where the journey ends
In a worthless claim
Time and again
In the mining game

I dug up a diamond
Rare and fine
I dug up a diamond
In a deep dark mine
Down in the darkness
In the dirt and the grime
I dug up a diamond
In a deep dark mine

Millennial shoppers will have diamond jewelry on their minds this holiday season thanks, in part, to a huge marketing push by the De Beers Group, which is set to spend $140 million by the end of the year. The budget is its biggest since 2008.

For those of you unfamiliar with De Beers, these are the same folks who introduced the world to "A Diamond Is Forever," a slogan penned by Frances Gerety, an NW Ayer copywriter, in 1947. That four-word tagline has inspired literature, music, a James Bond flick, and earned the title of the best advertising slogan of the 20th century by Advertising Age magazine.

Today, the De Beers Group has grown into an international powerhouse representing the interests of diamond exploration, diamond mining, diamond retail, diamond trading and diamond manufacturing. Among its many responsibilities is elevating the position of diamonds in the hyper-competitive luxury goods market.

“Total consumer expenditure on diamond jewelry for the last five years collectively has been the highest on record – and the outlook is positive," said Stephen Lussier, De Beers Group’s Executive Vice President of Marketing. "However, we cannot take future growth for granted."

The $140 million budget will be used to boost diamond jewelry demand in leading global markets, with the biggest allocations earmarked for the U.S., China and India. De Beers will continue to be laser focused on the emerging millennial generation — those born between 1982–2004.

“Increasing our spend from a strong position will help support continued demand in both mature and developing markets, particularly among millennials, who are already the largest group of diamond consumers despite this generation not having yet reached its maximum earning potential,” Lussier added.

The Diamond Producers Association, which is responsible for the "Real Is Rare. Real Is a Diamond" TV commercials, has seen its 2017 budget quadruple, compared to 2016.

“When evaluating luxury purchases, [millennials] seek items that are genuine, unique and not mass-produced, and have inherent meaning and value,” said Deborah Marquardt, the DPA’s Chief Marketing Officer. “This preference speaks directly to the diamond promise — in an increasingly artificial world, diamonds remain authentic, rare and precious.”

According to, the U.S. accounts for more than half of the world’s diamond purchases. Diamond sales in the U.S. reached $41 billion in 2016, an increase of 4.4% compared to 2015.

The picturesque town of San Marco dei Cavoti in southern Italy is now world famous for two things: 1) the delightful honey-and-nut confection known as torrone and 2) a diamond engagement ring that was miraculously liberated from a gap in one of its sidewalks — nine years after it was lost.

In the summer of 2008, New Jersey natives Margaret and Justin Mussel were staying with her parents in what may be the "sweetest" town in Italy when she noticed that her 1.1-carat diamond engagement ring was missing. They had visited Pompeii earlier in the day, so they assumed the ring was lost somewhere along the 80-mile span between the ancient city and her mom's home. They searched the house and its surroundings, but the ring was nowhere to be found.

Margaret remembered that the ring had been loose, but she wore it anyway.

"I felt terrible, and I knew I should have probably taken it off," she told ABC. "I just felt really bad that I could have prevented it from falling off, and I kept it on that day."

Worse yet, since the ring was lost on their trip abroad — and not in the U.S. — their insurance company would not replace it.

The heartbroken couple returned to Brick, N.J., with the understanding that the princess-cut diamond in the white gold four-prong setting was likely gone forever. Justin saved up for a few years and bought a replacement ring for Margaret. The lost ring slowly faded from their memories.

That's until the couple returned to San Marco dei Cavoti a few weeks ago, with their two young boys.

One evening, while lounging with his wife on his in-laws' front porch, Justin saw a brilliant reflection emanating from the sidewalk in front of the house. Each time a car would drive by with its headlights on, he saw a flicker.

"I kept saying to Margaret, 'Do you see that? I see this glimmer coming out of the sidewalk," he told ABC.

He thought the light might have been bouncing off a coin.

Armed with a screwdriver, Justin tracked the reflection to a gap in the stones that bordered the sidewalk. He pried the shiny object that was jammed in the crevice, and what emerged was Margaret's ring. The precious metal was slightly scratched, but the diamond was in perfect condition.

“I was like, ‘There's no way the ring is in there.' I couldn't believe it. I thought he was playing a joke,” she told ABC.

"Never in my wildest dreams did I ever think we would find it again,” she added.

“The odds of it falling into this crack, much less finding it nine years later, are astronomical,” Justin told the Asbury Park Press.

Justin believes the ring must have bounced into the gap with the stone facing down. Over time, it had been covered in dirt, but enough of the diamond was exposed to reflect the beams from the cars' headlights.

Margaret is now wearing her original engagement ring. The replacement ring will be for one of her boys when the time is right.

In 1926, at the age of 53, American tycoon Harrison Williams married Mona Bush, a divorcée 24 years his junior. Aboard his 250-foot yacht, the Warrior, the couple departed on a year-long, around-the-world honeymoon, and during a stopover in Sri Lanka (then Ceylon), the wealthiest man in America picked up a beautiful cornflower blue bauble for his new bride.

That 98.57-carat cushion-cut gem, which is now known as the Bismarck Sapphire, is one of the world's finest examples of September's official birthstone. Visitors to the Gem Gallery at the National Museum of Natural History in Washington, D.C., will see the Bismarck Sapphire Necklace prominently displayed between two other famous sapphire pieces, the Hall Sapphire and Diamond Necklace and the Logan Sapphire.

Originally set horizontally in a necklace designed by Cartier in 1927, the Bismarck Sapphire was rotated into a vertical position when Mona had the necklace updated in 1959. The necklace on display in Washington, D.C., is accented with eight square-cut blue sapphires and 312 baguette and round brilliant-cut diamonds.

Gem experts believe that the Bismarck Sapphire was originally much larger than 98.57 carats and that it was likely recut by Cartier to attain optimum clarity and brilliance after returning to the states from Sri Lanka. Traditionally, Sri Lankan cutters favored carat weight over ideal proportions.

With investments in public utilities, Williams had amassed a fortune estimated at $680 million (equivalent to about $9.6 billion today) — making him the richest man in America. But, the stock market crash of 1929 dissolved his fortune to a mere $5 million.

Still, the Williamses maintained their ritzy lifestyle and, by 1933, Mona had earned the distinction of becoming the first American voted the "Best Dressed Woman in the World."

Harrison Williams died in 1953, and two years later Mona would marry the German Count Eduard von Bismarck. At this point, the American socialite became known as Countess Mona von Bismarck. In 1967, at the age of 70, the Countess donated her beloved necklace to the Smithsonian. Mona died in 1983 at the age of 86.

Historically, the finest and most vibrant gem-quality sapphires have come from Sri Lanka, Burma and the Kashmir region of India. According to the Smithsonian, sapphires from Sri Lanka are typically light to medium blue and are commonly referred to as “Ceylon Sapphires.”

All sapphires are made of the mineral corundum (crystalline aluminum oxide). In its pure state, the corundum is colorless, but when trace elements are naturally introduced to the chemical composition, all the magic happens. Blue sapphires occur, for instance, when aluminum atoms are displaced with those of titanium and iron in the gem’s crystal lattice structure. Corundum has a hardness of 9 on the Mohs scale, compared to a diamond, which has a hardness of 10.

Sapphires are seen in many colors, including pink, purple, green, orange and yellow. Ruby is the red variety of corundum.
