Don’t Miss This: The Sun Will Morph Into a Diamond Ring on August 21

On Monday, August 21, skygazers from Salem, Ore., to Charleston, S.C., will see a rare total solar eclipse and — for just a brief moment — a fantastical celestial display that looks remarkably like a diamond ring.

The “Diamond Ring Effect,” which was first explained by Francis Baily in 1836, occurs when the moon completely masks out the sun during a total solar eclipse. Due to the rugged lunar landscape, the black outline of the moon is not smooth. Tiny beads of sunlight can still shine through in some places and not in others as the moon slowly grazes past the sun.

These are called Baily’s Beads. When only one dazzling “bead” remains, momentarily, the view of the eclipse resembles a diamond ring. The ring’s glow is produced by the sun’s corona remaining dimly visible around the lunar silhouette.

The Diamond Ring Effect will actually happen twice on August 21. The first time will occur in the moment just before the total eclipse, and the second will occur just after the total eclipse. The so-called Great American Solar Eclipse will last about 2 minutes and 40 seconds, and effectively turn day into night.

NASA warned that skywatchers should NEVER look at a partial solar eclipse without proper eye protection. Looking directly at the sun, even when it is partially covered by the moon, can cause serious eye damage or blindness. Only during totality, when the sun’s disk is completely covered by the moon, is it safe to view the eclipse with the naked eye, says NASA. Learn more about solar eclipse eye protection at Space.com.

During the solar eclipse, the moon’s shadow will pass over all of North America. The path of the umbra, where the eclipse is total, will stretch on a bent path from Salem on the West Coast to Charleston on the East Coast. This will be the first total solar eclipse visible in the contiguous United States in 38 years. The next total solar eclipse will take place in North America on April 8, 2024.

Found in Only One Location on Earth, Tanzanite Celebrates Its 50th Anniversary

It was exactly 50 years ago when a prospector named Manuel d’Souza got his first look at a cluster of intense blue crystals that had been discovered by a Maasai tribesman in the foothills of Mount Kilimanjaro in Tanzania.

At first glance, the crystals appeared to be sapphires. But a hardness test quickly ruled that out.

According to one published account, the somewhat perplexed prospector checked the characteristics of his samples against a resource guide and narrowed down the possibilities. Might they be olivine, or dumortierite, or cordierite or zoisite? The prospector took his best guess and registered an “olivine” claim with the Tanzanian government in the summer of 1967.

Later, the Gemological Institute of America revealed that the stones were, in fact, a never-before-seen variation of zoisite. To this day, a 2km by 4km area in Tanzania is the only place on the earth where this type of zoisite can be found.

The gorgeous blue mineral quickly caught the attention of Tiffany & Co., which wanted to feature the gemstone in a broad-based advertising campaign. The only problem was that the name “zoisite” sounded very much like “suicide,” and that wouldn’t do. So, the marketing team at Tiffany decided to promote the gems as “tanzanite,” a name that would honor its country of origin.

Tiffany’s marketing campaign earned tanzanite the noble title of “gem of the 20th century” and, in 2002, the American Gem Trade Association added tanzanite to the jewelry industry’s official birthstone list. Tanzanite joined turquoise and zircon as the official birthstones for December.

The most valuable tanzanite gemstones display a deep sapphire blue color with highlights of intense violet. The Smithsonian’s website explains that tanzanite exhibits the optical phenomenon of pleochroism, appearing intense blue, violet or red, depending on the direction through which the crystal is viewed.

Tanzanite rates a 6.5 to 7 on the Mohs hardness scale. By comparison, diamond rates a 10 and sapphire rates a 9.

A Maasai folktale recounts how tanzanite came to be. Once upon a time, the story goes, lightning struck the foothills of Mount Kilimanjaro, scorching the land. In the aftermath, a spectacular blue crystal was left shimmering in the ashes.

Tanzanite continues to shimmer in jewelry stores around the world as it celebrates its 50th anniversary.

MIT’s ‘Living Jewelry’ Is the High-Tech Version of Mexico’s Maquech Beetle

With a nod to the Maquech Brooch — a live beetle jewelry accessory famous on Mexico’s Yucatan Peninsula — students at MIT have invented tiny robot crawlers that can move across garments as “shape-changing and pattern-changing jewelry.”

Developed by the MIT Media Lab, “Project Kino” employs palm-sized robots that affix to clothing using magnets. The robots ride on wheels and are cloaked with colorful shields that can serve aesthetic and practical functions. The phrase “kino” is shorthand for “kinetic wearables.”

In one scenario, bots placed on the front of a dress can alter their positions in an odd bot ballet that give the garment an ever-changing look. In a second scenario, a bot fit with a microphone senses a phone call and quickly migrates to the top of the garment so the user can use it to chat with a caller. In a third scenario, the bots’ temperature sensors trigger a response to pull down a hood’s drawstrings.

Currently, MIT engineers are working through some technical challenges, such as extending the bots’ battery life, which now stands at about 45 minutes, and making them less clunky.

“We’re thinking of wearables as a personal assistant,” team member Cindy Hsin-Liu Kao told TechCrunch. “We think in the future, when they can have a brain of their own, they can learn your habits, learn your professional style, and when they get smaller, they can blend into the things you wear.”

Back in the Yucatan, the wingless Maquech beetle has been a favorite of tourists for decades. The bejeweled bug crawls on the wearer’s shirt within range of its three-inch-long chain “leash” that’s attached with a decorative safety pin.

The bugs don’t seem to mind having baubles glued to their backs, and they generally live for up to three years on a diet of apples and wet, rotted wood.

The Maquech beetles have played a romantic role in Yucatan foklore. According to legend, a Mayan princess fell in love with a prince from a rival clan. This was not permitted, so when they were discovered, the lover was sentenced to death. Recognizing their plight, a shaman changed the man into a shining beetle that could be decorated and worn over the princess’s heart as a reminder of their eternal bond.

Tourist shops in the Yucatan have been selling Maquech jewelry since the 1980s. The glittery crawlers cost about $10, but tourists are prohibited from bringing them into the U.S.

The video below offers a quick overview of “Project Kino.”

Music Friday: Emmylou Harris Would ‘Proudly Wear Your Wedding Ring’ If She Could Only Win Your Love

Welcome to Music Friday when we often bring you throwback tunes with jewelry, gemstones or precious metals in the title or lyrics. Today, country legend Emmylou Harris pledges eternal devotion to a noncommittal beau in her 1975 hit, “If I Could Only Win Your Love.”

In the song, Harris focuses on a very significant piece of jewelry while making the case for why her love interest should take the plunge.

In the very first verse, she sings, “If I could only win your love / I’d make the most of everything / I’d proudly wear your wedding ring / My heart would never stray one dream away.”

Originally written and performed by The Louvin Brothers in 1958, “If I Could Only Win Your Love” became a country hit 17 years later when Harris included it on her highly praised Pieces of the Sky album. The song shot to #4 on the Billboard Hot Country Singles chart and earned the #1 spot on the RPM Country Tracks chart in Canada.

Throughout a stellar career, which has spanned six decades, Harris has maintained a soft spot in her heart for The Louvin Brothers’ tune. While introducing the song in the video, below, Harris calls it her “first single.” This is significant because Harris would go on to release 70 singles, 26 studio albums, three live albums and 11 compilation albums. She has won 13 Grammys and was inducted into the Country Music Hall of Fame.

Now 70 years old and still touring internationally, Harris was born in Birmingham, Ala., to a Marine Corps officer dad and wartime military mom. Her dad endured 10 months as a prisoner of war in Korea when Emmylou was just five years old. She spent her childhood in North Carolina and was the class valedictorian of her high school. Later, she dropped out of college to pursue a music career in New York City. She worked as a waitress during the day and performed in Greenwich Village coffeehouses in the evening. She recorded her first album, Gliding Bird, in 1969.

Please check out the video of Harris’ performance of “If I Could Only Win Your Love.” The lyrics are below if you’d like to sing along…

“If I Could Only Win Your Love”
Written by Charlie and Ira Louvin. Performed by Emmylou Harris.

If I could only win your love
I’d make the most of everything
I’d proudly wear your wedding ring
My heart would never stray one dream away

If I could only win your love
I’d give my all to make it live
You’ll never know how much I give
If I could only win your love

Oh how can I ever say
How I crave your love when your gone away
Oh how can I ever show
How I burn inside when you hold me tight

If I could only win your love
I’d give my all to make it live
You’ll never know how much I give
If I could only win your love

Oh how (oh how)
can I ever say (can I ever say)
How I crave your love when your gone away
Oh how
can I ever show
How I burn inside when you hold me tight

If I could only win your love
I’d give my all to make it live
You’ll never know how much I give
If I could only win your love

Russian Mining Giant Trumpets Its Big-Diamond Cutting Prowess With the Unveiling of the 51-Carat ‘Dynasty’

Russian mining giant Alrosa trumpeted its big-diamond cutting prowess with the unveiling of The Dynasty, a 51.38-carat round brilliant-cut sparkler.

The 57-facet, D-color, VVS1 gem is the largest of five polished diamonds all culled from The Romanovs, a 179-carat rough stone recovered from the Nyurbinskaya kimberlite pipe in the Russian Republic of Sakha (Yakutia) in 2015. The cutting and polishing process took 18 months. All five stones will be offered for sale during an online auction in November.

The polished diamond collection, which is also called The Dynasty, represents a new initiative for the mining company, which produces more diamonds (in carats) than any other mining company in the world. Alrosa’s cutting division is stepping up its game in the arena of extra-large and colored diamonds.

“The creation of The Dynasty was of great importance,” noted Pavel Vinikhin, Director of Diamonds for Alrosa. “This stone gives a start to a new stage in the development of Alrosa’s cutting division. The Dynasty demonstrated that we acn do it at the highest level. We work a lot on the technique, combining modern technologies with the secrets of jewelers of the Russian Imperial Court.”

Alrosa named the collection The Dynasty to revive the traditions and memory of renowned Russian jewelers, who were famous for their craftsmanship and filigree. Russia’s first cutting and polishing factory was founded by Peter the Great early in the 18th century.

Other diamonds in the collection are named after the dynasties that played a crucial role in the development of Russian jewelry. A 16.67-carat round brilliant-cut diamond, the second by weight, was named The Sheremetevs. The Orlovs is a 5.05-carat oval diamond. The Vorontsovs is a 1.73-carat pear-shaped diamond and The Yusupovs is a 1.39-carat oval diamond.

Spinel — the New August Birthstone — Has Been Fooling Royalty for Centuries

Fourteen months ago, the American Gem Trade Association (AGTA) and Jewelers of America (JA) announced that spinel — the great imposter — would be joining peridot as an official birthstone for the month of August. It was only the third time in the past 105 years that the modern birthstone list had been amended.

The industry associations noted at the time that they were responding to a strong call from gem enthusiasts to expand the list of official birthstones. The spinel was designated for August because of its historical significance and its rich, red color.

Spinel has been called “the great impostor of gemstone history” because some of the most famous “rubies” seen in crown jewels around the world are actually spinels. According to the Smithsonian, it wasn’t until 1783 that spinel was recognized as a mineral distinct from corundum (ruby and sapphire). Ruby is composed of aluminum oxide, while spinel is made of magnesium aluminum oxide. Both get their reddish color from impurities of chromium in their chemical structure.

For centuries, royal jewelry “experts” could not tell the difference between a ruby and a spinel.

For instance, the 398-carat ruby-red gem that tops the Imperial Crown of Russia commissioned by Catherine the Great in 1763 was thought to be a ruby, but turned out to be a spinel. The 361-carat Timur Ruby, which was presented by the East India Company to Queen Victoria as a gift in 1851, was also later identified as a spinel. And the 170-carat Black Prince Ruby, which is prominently displayed on the Imperial State Crown of England, was, in fact, an uncut spinel.

While spinel is best known for its ability to imitate the color of ruby, the gem comes in a variety of vibrant colors, including soft pastel shades of pink and purple, fiery oranges, and cool hues ranging from powdery gray to intense blue. It is a durable gem with a hardness of 8.0 on the Mohs scale. By comparison, diamond rates a 10 and ruby rates a 9.

Shown in the image, above, are three spinels from the National Gem and Mineral Collection at the Smithsonian’s National Museum of Natural History in Washington, D.C. The first and third gem were sourced in Sri Lanka and weigh 22.2 and 29.7 carats, respectively. The spinel in the center is from Myanmar and weighs 36.1 carats.

The bracelet shown here contains 98 natural spinel crystals set in a double row in yellow gold. The stones were sourced in the Mogok region of Myanmar and the piece is currently part of the National Gem and Mineral Collection.

Myanmar is known to produce some of the most beautiful spinels — especially the pink, red and orange-red varieties. Spinels are also mined in Afghanistan, Brazil, Cambodia, Kenya, Russia, Sri Lanka, Tanzania, Thailand and Vietnam.

Hawaii’s Amazing Green Beach Is Blanketed With Olivine Crystals Eroded From an Ancient Volcanic Formation

Imagine walking barefoot on a blanket of sparkling green sand that owes its astounding color to olivine crystals eroded from an ancient volcanic formation and delivered to the shore by ocean waves.

Mahana Beach on Hawaii’s Papakolea coast is one of only three green sand beaches in the world. The beach sand on the Big Island’s undeveloped southern tip is rich in the mineral olivine (Gem-quality olivine is known as peridot, the August birthstone). Olivine is a common mineral component of Hawaiian lavas and one of the first crystals to form as magma cools.

Locals refer to peridot as the “Hawaiian Diamond,” and small peridot stones are sold as “Pele’s tears” in honor of Pele, the goddess of volcanoes. In ancient Hawaiian chants, Pele was described as “She-who-shapes-the-sacred-land,” and her temper was known to be both as abundant and dangerous as the lava.

Those daring enough to take the three-mile hike through lava fields to the remote beach at the crescent-shaped bay of Pu’u Mahana, will be treated to a display of one of nature’s crowning achievements — a green beach that appears surreal against the backdrop of steely grey cliffs, turquoise blue ocean and bright blue sky. The hike will take about an hour, but locals offer rides to the beach in the back of a pickup truck for $15 in each direction.

The abundance of olivine crystals filling the beach comes from the eroded cutaway interior of Pu’u Mahana, a volcanic cone produced more than 49,000 years ago by the explosive combination of lava and groundwater. Once you’ve enjoyed the wonders of Mahana Beach, you can complete the green-beach trifecta by visiting the world’s other two olivine-covered destinations — Talafofo Beach on Guam and The Green Beach on Floreana Island in The Galápagos.

The official birthstone for August, peridot is one of the few gemstones that occur in only one color: generally an olive green. The amount of iron in the crystal structures determines the intensity and tint of the green color. Specimens can range from yellow-green through olive green to brownish green. The dark-olive color is the most valuable.

Ultra-Rare 2.11-Carat Fancy Red Diamond Headlines 2017 Argyle Pink Diamonds Tender

An ultra-rare, 2.11-carat, fancy red diamond known as the Argyle Everglow headlines the 2017 Argyle Pink Diamonds Tender – an annual showcase of the rarest diamonds from Rio Tinto’s Argyle mine in Western Australia.

The Argyle Everglow, which earned a grade of fancy red VS2 from the Gemological Institute of America (GIA), is the largest fancy red diamond ever to appear at an Argyle Pink Diamonds Tender. One gem expert told CNN that he believes the radiant-cut gem may sell for $10 million or more.

If the Argyle Everglow achieves that price, 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 million, or a bit over $4 million per carat.

“We are delighted to announce this historic diamond at our Tender preview, a testament to the unique Argyle ore-body that continues to produce the world’s rarest gems,” noted Rio Tinto Copper & Diamonds chief executive Arnaud Soirat.

Fancy red diamonds are so rare that the Tender typically releases only four, or so, per year. In fact, 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 Argyle Everglow represents rarity within rarity and will drive global demand from collectors and connoisseurs in search of the incomparable,” added Argyle Pink Diamonds manager Josephine Johnson.

The 2017 Tender, known as “Custodians of Rare Beauty,” comprises 58 diamonds weighing a total of 49.39 carats.

The collection includes five “hero” diamonds selected for their unique beauty and named 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

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.

The 2017 Argyle Pink Diamonds Tender will be showcased in New York, Hong Kong and Perth with bids closing on October 11, 2017.

Music Friday: Tim McGraw’s Girlfriend Has an Eye for Things That Glitter in ‘Just to See You Smile’

Welcome to Music Friday when we bring you hit songs with jewelry, gemstones or precious metals in the title or lyrics. Today, we feature superstar Tim McGraw singing Billboard‘s #1 country hit of 1998, “Just to See You Smile.”

In this song about selflessness, unconditional love and heartbreak, McGraw portrays a hard-working Texas miner who is willing to do just about anything to make his girlfriend happy — and that includes lavishing her with fine jewelry.

In the very first lines of the song, McGraw sings, “You always had an eye for things that glittered / But I was far from bein’ made of gold / I don’t know how but I scraped up the money / I just never could quite tell you no.”

The miner leaves his job in Amarillo to relocate with her to Tennessee, but the relationship quickly breaks down. The girlfriend finds a new lover and our hero graciously tells her that he’s happy for her.

“And given the chance I’d lie again,” he admits. “It’s worth all that’s lost / Just to see you smile.”

Released in August 1997, the song would go on to spend 42 weeks on the Billboard Country chart — the longest chart run for any country single in the 1990s.

“Just to See You Smile” was the third single from McGraw’s fourth studio album, Everywhere. Both the song and the album topped the Billboard Country charts.

The son of New York Mets star pitcher Tug McGraw, Samuel Timothy “Tim” McGraw was born in Delhi, La., in 1967. Tim was brought up by his step-dad, Horace Smith, and didn’t know that the famous athlete was his biological father until he was 11. He signed his first record deal with Curb Records in 1990 and married country singer Faith Hill in 1996.

McGraw has sold more than 40 million albums worldwide, and 25 of his singles have gone to #1 on the Billboard U.S. Hot Country Songs chart. He has also won three Grammy Awards, 14 Academy of Country Music awards, 11 Country Music Association (CMA) awards, 10 American Music Awards and three People’s Choice Awards.

Please check out the audio track of McGraw’s performance of “Just to See You Smile.” The lyrics are below if you’d like to sing along…

“Just To See You Smile”
Written by Mark Nesler and Tony Martin. Performed by Tim McGraw.

You always had an eye for things that glittered
But I was far from bein’ made of gold
I don’t know how but I scraped up the money
I just never could quite tell you no
Just like when you were leavin’ Amarillo
To take that new job in Tennessee
And I quit mine so we could be together
I can’t forget the way you looked at me

Just to see you smile
I’d do anything
That you wanted me to
And all is said and done
I’d never count the cost
It’s worth all that’s lost
Just to see you smile

When you said time was all you really needed
I walked away and let you have your space
Cause leavin’ didn’t hurt me near as badly
As the tears I saw rollin’ down your face
And yesterday I knew just what you wanted
When you came walkin’ up to me with him
So I told you that I was happy for you
And given the chance I’d lie again

Just to see you smile
I’d do anything
That you wanted me to
And all is said and done
I’d never count the cost
It’s worth all that’s lost
Just to see you smile

Just to see you smile
I’d do anything
That you wanted me to
And all is said and done
I’d never count the cost
It’s worth all that’s lost
Just to see you smile

Maine Man Gets to Propose All Over Again After Rescuing Engagement Ring From Under a Waterfall

So, you thought finding a needle in a haystack was tough. How about finding a diamond engagement ring at the bottom of a cascading — and very cold — waterfall?

That was the challenge for Maine resident Evan Nadeau, whose fiancée, Erin Helfen, had lost her solitaire ring while swimming under the Buttermilk Falls in scenic central Maine. The couple had enjoyed a day of hiking and swimming, but it wasn’t until later that Helfen realized her ring was missing.

“It was awful,” Helfen told local CBS affiliate WABI. “We had just come out of a swimming hole and [then] we had hiked about a quarter of a mile. I’m one of those people who kind of fidgets with her rings, so I was about to fidget with it when I looked down and it wasn’t there. I was just like, ‘Oh my God, oh my God.'”

After inspecting some selfies that they took during their trip, the couple could tell that the ring was on Helfen’s finger when they got to the falls, but was missing after their swim. They were pretty sure the ring had found its final resting place at the bottom of the falls.

Helfen and Nadeau have a wedding planned for September 23, so the loss of their engagement ring was particularly heart wrenching. It hadn’t been insured and the couple was not able to replace it.

But then, two weeks after the ring was lost, Nadeau was not ready to give up. He had formulated a new plan to get his fiancée’s ring back. The future groom scooped up his diving gear and made a solo 70-mile drive back to the falls. Despite the frigid water, he was determined to spend hours submerged, scouring every nook and cranny of the rocky bottom while getting pummeled by the torrent. Nadeau said the water was so cold that his knees turned blue.

Despite impossible odds, Nadeau spotted the ring.

“After about the second hour in the water, after combing the area really well, I just saw the two prongs on her ring,” Nadeau told WABI. “Her band had been wedged under a rock… The next thing you know I had the ring on my finger. I couldn’t believe it. There was somebody looking out for me because there’s no way I should have found that.”

Instead of calling his fiancée with the good news, Nadeau kept his miraculous find a secret until he got back home.

Helfen greeted Nadeau as he pulled up in his truck. He told her that it was a hard, long day and that he got sick of being in the water. He was getting tired of it.

And then he said, “Well, what I don’t get tired of is asking you to marry me.”

Nadeau, who is a Registered Nurse at Eastern Maine Medical Center, pulled the ring out of his pocket and proposed again.

Helfen, who just earned her Master’s degree in speech-language pathology at the University of Maine, believes that the ring symbolizes how the couple was “just meant to be together.”

Nadeau couldn’t be happier. “She got her sparkle back,” he said.
