Welcome to Music Friday when we bring you great songs with jewelry, gemstones or precious metals in the title or lyrics. Today, country music legend George Jones sings about finally finding that special someone in his 1987 hit "The Right Left Hand."


In the song, Jones sadly recounts how he's cried a million tears over relationships that had come undone. But now he can rejoice because the Lord has given him "a true love of a lady" who "lets him know her love is here to stay."

He sings, "So I put a golden band on the right left hand this time / And the right left hand put a golden band on mine / When our hair is snowy white / Time will prove I'm right / I put a golden band on the right left hand this time."

Songwriters A.L. "Doodle" Owens and Dennis J. Knutson use a clever play on words to describe Jones' true love in relation to the others. Jones sings about placing the ring on the "right" left hand — as opposed to the wrong one — this time.

Music critics believe the song is a tribute to Jones's fourth wife, Nancy, whom he credited with saving his life and career. He married Nancy in 1983 and successfully emerged from a dark time brought on by his alcoholism. With Nancy's nurturing, he was also able to stage a comeback and revitalize his reputation as an A-lister on the country music scene.

"The Right Left Hand," which was the third track from Jones's 1986 album Wine Colored Roses, peaked at #8 on the U.S. Billboard Hot Country Singles chart. The album also performed well, hitting #5 on the U.S. Billboard Top Country Albums chart.

Born in a log cabin in the small town of Saratoga, Texas, Jones got his first guitar at the age of nine. By 1955, at the age of 24, Jones had already served in the Marines, was married twice and recorded his first hit song, "Why Baby Why." In 1969, he married Tammy Wynette. They were divorced six years later, although they continued to perform together after the breakup.

Jones told Billboard in 2006 that when it comes to his music, "It's never been for love of money. I thank God for it because it makes me a living. But I sing because I love it, not because of the dollar signs."


Over a career that spanned seven decades, Jones is credited with charting 168 country songs. He was inducted into the Country Music Hall of Fame in 1992. Jones passed away in 2013 at the age of 81 and rests at the Woodlawn Cemetery in Nashville, Tenn.

Please check out the video of Jones's live performance of "The Right Left Hand." The lyrics are below if you'd like to sing along...

"The Right Left Hand"
Written by A.L. “Doodle” Owens and Dennis J. Knutson. Performed by George Jones.

I've cried a million tears,
Down through the years
Searching for that special one
And the vows I took before,
Were all forever more,
But no matter how I tried they came undone

Then the good Lord finally gave me
A true love of a lady,
Someone who believes in me
And she lets me know each day,
That her love is here to stay
Lord I finally found someone who'll never leave

So I put a golden band on the right left hand this time,
And the right left hand put a golden band on mine
When our hair is snowy white,
Time will prove I'm right
I put a golden band on the right left hand this time

I'll never have to plead
For the love that my heart needs,
She'll be close enough to touch
And when the nights are long and cold,
She'll be there to hold,
All dressed up for one more night of love

I put a golden band on the right left hand this time,
And the right left hand put a golden band on mine
When our hair is snowy white,
Time will prove I'm right
I put a golden band on the right left hand this time

I put a golden band on the right left hand this time

The Ostro Stone — the world's largest faceted intense blue topaz at 9,381 carats — made its public debut at London’s Natural History Museum yesterday.


Unearthed by gemstone pioneer Max Ostro in the Amazon rainforest in 1986, the flawless gem was expertly cut and polished into a oval shape and then locked away in a vault for three decades.

After Max's death in 2010, his son Maurice decided it was time for the public to enjoy the gemstone's magnificence. Recently, he gave the gem to London’s famed Natural History Museum on permanent loan.


“Collecting beautiful colored gems was my father’s passion," said Maurice Ostro, the chairman of Ostro Minerals, "My mission is to leverage his remarkable legacy in a way that would make him proud. We are delighted that the finest of his gemstones will now be part of the collection at the Natural History Museum, [which shares] our passion for exceptional stones.”

Max Ostro founded Ostro Minerals in 1960, and his company grew to be a leading producer of blue topaz. The senior Ostro is credited with refining the nomenclature used to describe the various colors of topaz. For instance, he coined the term “London Blue” and “Swiss Blue.”


The PBS NewsHour caught up with Maurice during a photo shoot leading up to The Ostro Stone's debut.


"Having tried to hold it for photography, I can tell you it is very heavy," Ostro told PBS NewsHour.

In fact, the gem is nearly six inches long, 4.5 inches wide and weighs a surprising 4.1 pounds.

Topaz comes is a wide variety of hues and saturations, but The Ostro Stone is in a class by itself.

"What is amazing about this stone is not just its size," Ostro told PBS NewsHour. "It’s its quality. The color, the intensity of the blue and the clarity of the stone are what makes it so exceptionally rare."

The museum announced that it would boost security to ensure the gemstone's protection. London's Natural History Museum welcomes more than five million visitors a year and is a world-leading science research center.

Made famous in the landmark 1939 film The Wizard of Oz, Dorothy's Ruby Slippers have been a popular attraction at the Smithsonian in Washington, D.C., for more than three decades.


But the 77-year-old slippers are showing their age. The color has faded and the slippers appear dull and washed-out. The ruby-red sequins that once gave the shoes their vibrant color are flaking and some of the threads holding the sequins in place have frayed.


Conservationists at the Smithsonian’s National Museum of American History are looking to give Dorothy's slippers a well-deserved facelift and a new state-of-the-art display case designed to protect them from environmental harm and slow their deterioration.

The price tag to accomplish these goals is $300,000, and although U.S. taxpayers do fund the core functions of the Smithsonian, there are no funds available for the Ruby Slippers project.

So the Smithsonian is embarking on a Kickstarter campaign to generate $300,000 within 30 days. The two-day-old campaign has already generated more than $117,000 from 2,100 backers. Tony Award-winning Broadway costume designer William Ivey Long has created a series of Thank You gifts for contributions ranging from $10 to $100. These include posters, tote bags and t-shirts.


Those who contribute $10,000 will enjoy a rare, behind-the-scenes look at the conservation of the Ruby Slippers.

If the fundraising effort is successful — and at this pace it certainly will be — the revitalized slippers with be at the center of a new multimedia exhibition titled "On With the Show," which is scheduled to make its Smithsonian debut in 2018.

This is not the first time the Smithsonian has turned to Kickstarter to fund an important conservation project. In July 2015, the Smithsonian sought $500,000 to conserve and digitize the spacesuits of Alan Shepard and Neil Armstrong. The “Reboot the Suit” campaign ultimately raised $719,000.

Acknowledged as one of the most iconic artifacts in film history and often called "the most famous pair of shoes in the world," the Ruby Slippers displayed in the American Stories section of the National Museum of American History were donated anonymously in 1979.

Movie historians believe that MGM’s chief costume designer Gilbert Adrian created multiple pairs of ruby slippers for the film, but only four pairs are known to still exist. The Smithsonian's pair is the one Dorothy wore when she followed the Yellow Brick Road.


A second pair was stolen from the July Garland Museum in 2005; a third pair was purchased in 2012 by Leonardo DiCaprio and other benefactors on behalf of the Academy of Motion Picture Arts and Sciences; and a fourth pair is owned by a private collector in Los Angeles.

In the 1900 children's novel The Wonderful Wizard of Oz by L. Frank Baum, Dorothy's slippers were made of silver. According to film lore, screenwriter Noel Langley recommended that they be changed to ruby red so they would stand out better on the yellow brick road when shot in brilliant Technicolor.


Interestingly, Dorothy's Ruby Slippers are not made of ruby at all. In fact, the bugle beads that prop designers used to simulate ruby proved to be too heavy. The solution was to replace most of the bugle beads with sequins, 2,300 on each slipper. The butterfly-shaped bow on the front of each shoe features red bugle beads outlined in red glass rhinestones in silver settings.

Samford University junior linebacker Deion Pierre recruited his teammates to assist in an unforgettable postgame marriage proposal on Saturday.


Right after the Bulldogs' convincing 55-21 win over VMI, Pierre and his squad — still in full football gear — surprised Jasmine Henderson at the 50 yard line with a choreographed presentation set to Ed Sheeran’s "Thinking Out Loud."

Henderson was clearly caught off guard when the music started to play on the loud speakers and the Bulldog players shuffled toward her at midfield with roses in hand. The players slowly danced a circle around Pierre's girlfriend.

Then Pierre entered the circle, held his girlfriend's hand and dropped to one knee.


Each of the players placed a rose on the turf and tightened their circle around the couple.

Pierre asked Henderson if she would marry him and she said, "Yes." Pierre placed a diamond ring on her finger and the couple embraced.

The 6'3" 230 lb. linebacker from Pembroke Pines, Fla., scooped up his girlfriend and lifted her in the air as his teammates raised their arms and erupted in a chant, "She said yes! She said yes!"


In a video posted by Samford University Athletics, a beaming Pierre tells the interviewer about his best day ever. Earlier in the day, he had a 21-yard interception return for a touchdown and then his girlfriend accepted his marriage proposal. "Pick six. I won twice today," he said.

When asked if she was surprised by the elaborate proposal, the shy, soft-spoken Henderson said, "Yes." When asked how she felt, she answered, "I feel great."

Pierre told that when he met Henderson it was love at first sight.


"I told my friend, '[She's] going to be my wife one day.' And then when I got to meet her and got to know her personality, she's the greatest person I know, besides my mom," Pierre said.

Pierre and Henderson are both juniors and will wait until after graduation to get married.

Check out the awesome proposal video below...

It's not easy to render a cartoon penguin in precious metals and gemstones, but that was exactly the challenge Jostens faced when tasked with designing the 2016 Stanley Cup rings for the champion Pittsburgh Penguins.


The team's iconic logo crest features a black penguin skating with a hockey stick across a golden triangle that represent the shape of downtown Pittsburgh.

Jostens used a custom-cut black onyx to represent the shape of the penguin and a half-carat pear-shaped diamond to mimic the penguin's white torso. The blade of the hockey stick is a single tapered baguette diamond. The golden triangle is made up of 18 yellow diamonds set in yellow gold.

Thirty custom-cut princess-cut diamonds are set in a circle around the perimeter of the logo, with an additional 15 round diamonds set behind the logo crest. The words "STANLEY CUP" and "CHAMPIONS" frame the top and bottom edges of the ring in yellow gold. The use of yellow gold highlights on the white gold ring brings contrast and depth to the design.

In total, the Stanley Cup championship rings are adorned with 309 diamonds weighing 8.8 carats.


The edges of the top and sides of the ring are waterfall set with diamonds, making for smooth, cascading edges and a streamlined aesthetic. The left side panel proudly displays the team name, the player’s last name and the player’s number elegantly set with pavé diamonds.


The right side panel features the year “2016” and four Stanley Cup trophies, representing each of the franchise’s championship victories for the City of Pittsburgh.


The inside of the ring is engraved with the team motto “Just Play” and the records of the four playoff series wins on the path to the Stanley Cup.


The 2016 Stanley Cup champions, who beat the San Jose Sharks in the final round of the playoffs, received their impressive rings last week during a private ceremony at the Heinz History Center in Pittsburgh. Only a few days earlier, the team was honored at The White House by President Barack Obama.

"These unique and brilliant rings will always be an inspiring symbol of what our players and coaches accomplished by winning the Stanley Cup," said Penguins president and CEO David Morehouse. "On behalf of our owners, Mario Lemieux and Ron Burkle, as well as our players and coaches, I want to thank Jostens for the creativity and craftsmanship that went into this very special Stanley Cup championship ring project.”

Welcome to Music Friday when we bring you awesome new songs with jewelry, gemstones or precious metals in the title or lyrics. Today, RaeLynn — who is best known as a finalist in Season 2 of The Voice — sings about how an engagement ring embodies a lifelong pledge of love and devotion in her 2016 release, "Diamonds."


In the song, RaeLynn acknowledges that diamonds are exciting, but explains that nothing can compare to receiving a diamond engagement ring from the one you love.

She sums up her feelings in the chorus of "Diamonds"... "Cause a diamond's just a diamond til you put it on the right left hand / Love is just a word til you feel it and finally understand / That some things don't mean anything til one day they mean everything / And you're flyin', smilin' and shinin' / Kinda like diamonds / Kinda like diamonds."

The 22-year-old RaeLynn, whose given name is Racheal Lynn Woodward, told The Knot how her October 2015 engagement to Josh Davis inspired her to write the song.

"The day after I got engaged, I was looking at my engagement ring and how beautiful it was," she said. "And all I could think about was how much Josh meant to me — and that this ring would just be a ring without him. What makes it so special is it sealed a promise to the man I love for the rest of my life."

The couple wed in February of 2016.

“When you meet the right one, you have to go with it,” RaeLynn told The Knot. “Love is real. Love is the greatest gift God could give us. Just like ‘Thing About Us’ was my [wedding] song with Josh, I hope maybe ‘Diamonds’ can be your wedding song [someday].”

"Diamonds" is the eighth track from RaeLynn's soon-to-be released album WildHorse. The single hit the airwaves last week and the album is set to drop on December 2.

The singer/songwriter from Baytown, Texas, auditioned for the second season of The Voice in 2012. As a member of Team Blake, she made it all the way to the quarterfinals before being eliminated. In June of this year, RaeLynn signed a new record deal with Warner Bros. Nashville.

She named her upcoming album WildHorse because the album's tracks reflect RaeLynn's carefree spirit and unconventional way of looking at life. The album is a retrospective of her past four years, a roller-coaster ride that saw her graduate from high school, move away from her parents, fall in love, have her heart broken, fall in love again, get engaged and then marry the man of her dreams.

In October of 2015, RaeLynn showed off her beautiful marquise-shaped diamond engagement ring in a series of romantic Instagram posts. She captioned one of the pics, "Can’t believe I get to marry my best friend. Ahhhhhhhh."

We hope you enjoy RaeLynn's newest release. The video and lyrics are below...

Written by Emily Weisband, Jimmy Robbins and RaeLynn. Performed by RaeLynn.

There's one sittin' in a pawn shop, glass counter, someone down in California traded it for a TV
Another one in a pretty blue box somewhere up in New York, white ribbon, Tiffany's
One's catchin' dust in a drawer in a dresser at your grandma's house that's been there since 1953
But honestly

A diamond's just a diamond til you put it on the right left hand
Love is just a word til you feel it and finally understand
That some things don't mean anything til one day they mean everything
And you're flyin', smilin' and shinin'
Kinda like diamonds
Kinda like diamonds

I ain't saying they aren't pretty and the way they feel doesn't feel just like an answer to a little girls dream
Ain't saying they ain't fun to show off to your friends and get the chills when you hear them scream
But if your hearts not in it, forget it

Cause a diamond's just a diamond til you put it on the right left hand
Love is just a word til you feel it and finally understand
That some things don't mean anything til one day they mean everything
And you're flyin', smilin' and shinin'
Kinda like diamonds
Kinda like diamonds

I don't need one just to hold on to
I don't want one unless it comes with you

Cause a diamond's just a diamond til you put it on the right left hand
Love is just a word til you feel it and finally understand
That some things don't mean anything til one day they mean everything
And you're flyin', smilin' and shinin'
Kinda like diamonds
Kinda like diamonds

On January 26, 1905, Captain Frederick Wells was conducting a standard inspection of the Premier Mine in South Africa when a glint off the wall of the mine caught his attention. At first, he thought it was a shard of glass that may have been embedded there by a miner as a practical joke. But, then he pulled out his pocket knife and pried the object from the wall.


What he extracted was the now-famous 3,106-carat Cullinan Diamond, the largest gem-quality rough diamond ever discovered. The Cullinan weighed 621 grams (1.37 pounds) and was 98mm (3.85 inches) long, 57mm wide and 67mm tall.

For the next 111 years, diamond miners have dreamed of another Cullinan, but none have gotten close to securing a gem of that size.


Even last year's amazing recovery of a 1,109-carat diamond from Lucara's Karowe mine in Botswana paled in comparison to the Cullinan. The Lesedi La Rona is barely 36% of the weight of the diamond standard-bearer.


The biggest obstacle to securing enormous diamonds — intact — is the violent method mining companies use to process the diamond-bearing rock. Typically, the material has been drilled, blasted, hauled and put through crushing machines to get to the gems that may be hiding within. During that process, extremely large diamonds, some weighing hundreds of carats, are often damaged or even pulverized.

Lucara revealed that the 1,109-carat Lesedi La Rona actually weighed 1,483 carats, but a large chunk was a broken off during the sorting process. Lucara CEO William Lamb told at the time that it was actually fortunate that the 374-carat chunk broke off because Lucara’s plant was not designed to process such large material. A 1,500-carat diamond would have been crushed.

Last week, we noted that Lucapa Diamond Co. is about to go online with a new sorting machine that can recover diamonds up to 1,000 carats in size at its Lulo processing plant in Angola.

Now, is reporting that Lucara and Gem Diamonds Ltd. have their eyes on an even bigger prize.

Both are stepping up their investments in Large Diamond Recovery (LDR). The companies are installing bigger, costlier filters and laser identification technology so huge diamonds can be cherry picked before the ore goes through the crushing process. The new recovery technology will be implemented at both Lucara’s Karowe mine in Botswana and Gem Diamonds Ltd.’s Letseng mine in Lesotho.

Lucara's recently completed plant modifications are designed to sift diamonds as large as 90 millimeters (3.5 inches) in diameter and would allow for the recovery of a gem comparable in size to the 3,106-carat Cullinan.

"The Sky Blue Diamond" is the latest in a procession of majestic fancy vivid blue diamonds that have captivated the auction world over the past 12 months.


Weighing 8.01 carats, "The Sky Blue Diamond" is the headliner of Sotheby’s Magnificent Jewels and Noble Jewels sale, which is set to take place in Geneva on November 16. The square-cut gem, which is set in a ring by Cartier, boasts the highest possible color grading, an excellent polish and a purity rating of Type IIb, a rare category representing less than 0.5% of all diamonds. Sotheby's set the pre-sale estimate at $15 million to $25 million.

If the ring sells at the top of the estimated range, it would yield $3.12 million per carat and rank among the finest fancy vivid blue diamonds of all time.


Blue diamond lovers may remember that "The Blue Moon of Josephine" established a new record for the highest price paid per carat for any gemstone when the hammer went down at Sotheby's Geneva in November 2015. The internally flawless 12.03-carat cushion-shaped fancy vivid blue diamond sold for $48.5 million, or $4.03 million per carat.


In May 2016, "The Oppenheimer Blue" became the priciest gem ever auctioned when it sold for $57.5 million at Christie's Geneva. The fancy vivid blue step-cut, rectangular-shaped diamond weighed 14.62 carats and earned a clarity rating of VVS1. Its price per carat was $3.96 million.

“The Sky Blue Diamond is of a wonderfully clear celestial blue, presented in an extremely elegant square emerald cut – in my view, the most flattering of all the cuts for a colored diamond," commented David Bennett, Worldwide Chairman of Sotheby’s International Jewelry Division. "This important gem will, I am sure, captivate all collectors of exceptional gemstones.”

The Sky Blue Diamond and other top lots from the Magnificent Jewels and Noble Jewels sale will tour London (October 13-17) and New York (November 4-6) before returning to Geneva for the auction.

First-time prospectors Dan Frederick and his daughter, Lauren, scored a 2.03-carat white diamond within 60 minutes of searching the side of a plowed furrow at Arkansas’s Crater of Diamonds State Park last Tuesday.


Dan Frederick, who hails from Renton, Wash., and Lauren, who lives in Los Angeles, traveled 2,200 and 1,600 miles, respectively, to prospect for gems together at the only diamond site in the world that allows treasure hunters to keep whatever they find. The entry fee cost them $8 apiece.


The Fredericks had never visited the Crater of Diamonds State Park before and planned their trip to Arkansas after searching the internet for "places to find gems."

Dan Frederick noted that he and his daughter started their search for gems at 8 a.m., and by 9 a.m. Dan had spotted the diamond's metallic shine on top of the ground near the Star of Arkansas diamond marker on the north end of the park’s 37.5-acre diamond search area. The Fredericks named their find "The Lucky Diamond."


Lauren Frederick told that the diamond "was the cherry on top of a fun and special trip."

"Finding the diamond will be one of my favorite memories, especially since my dad and I found it together," she said.

Park Interpreter Betty Coors described the diamond as having a pearly white color and a distinct triangular shape that results when two diamond crystals share part of the same structure during formation deep within the earth. These twinned crystals are called "macle" gems.

Larger diamonds are occasionally found on the surface of the search area by park visitors. Diamonds are a bit heavy for their size, and when rain washes dirt away, they are sometimes exposed right at the top. When the sun comes out, they sparkle and are easier to spot.

“Dan Frederick has proven, once again, that it is possible to find large, beautiful diamonds while surface searching," Coors said in a statement. "This is an example of a diamond that all park visitors dream of taking home.”

The Fredericks have yet to decide whether they will have their diamond faceted and polished or leave it in its natural state.

The search field in Murfreesboro, Ark., is actually the eroded surface of an ancient diamond-bearing kimberlite pipe. The park maintains a generous finder’s keepers policy and even provides experts to help amateur prospectors identify what they’ve found. Besides diamonds, the search field often yields amethyst, garnet, peridot, jasper, agate, calcite, barite and quartz.


More than 75,000 diamonds have been pulled from the Murfreesboro site since farmer John Huddleston, who owned the land, found the first precious gems in 1906. The site became an Arkansas state park in 1972. The largest diamond ever discovered in the U.S. was unearthed here in 1924. Named the Uncle Sam, the white diamond with a pink cast weighed an astounding 40.23 carats.

The excitement of finding a precious gemstone has made Arkansas’s Crater of Diamonds State Park a popular family-fun attraction. In 2015, the park welcomed 168,000 visitors, compared to 51,000 just 10 years earlier.

There's an ancient Egyptian legend that describes how tourmalines got their amazing colors, and it goes something like this... On their long voyage up to the surface from the center of the Earth, tourmalines passed through a rainbow — and by doing so, assumed all of its colors.


The name "tourmaline" is derived from the Singhalese words "tura mali," which mean "stone with mixed colors." In fact, when it comes to color, tourmaline is the undisputed champion of the gemstone world.

Not only does tourmaline display fiery, vibrant colors, such as blue, red, green, yellow, orange, brown, pink, purple, gray and black, but the official October gemstone also comes in bi-color and tri-color versions. (The other official birthstone for October is opal.)

One of our multicolor favorites is called "watermelon tourmaline" because it features green, white and pink bands that look very much like a slice of the delicious summer fruit. Designers love to use thin, polished cross-sections of watermelon tourmaline in their work. Gem collectors love watermelon tourmaline because it's fun and so unusual.

According to the American Gem Society, the multicolor gems with the clearest color distinctions are the most highly prized.

The trade has unusual names for the wide variety of multicolor tourmalines. According to the International Colored Gemstone Association, colorless crystals with black on both ends is called "Mohrenkopf," a chocolate-coated marshmallow treat sold in the German-speaking part of Switzerland.


Tourmaline crystals that have banded color zones that lie on top of one another are referred to by the Brazilians as "papageios" or "rainbow tourmaline." A tourmaline with red on one end is called a "Turk's head tourmaline." Apparently, the reference is a nod to the red fez cap made popular in Turkish culture.

Tourmaline is found many locations around the world, including the U.S. (mainly California and Maine), Brazil, Afghanistan and East Africa.

Tourmalines get their color from trace elements that are introduced to gem's chemical structure. Lithium-rich tourmalines yield blue, green, red, yellow and pink colors, while iron-rich tourmalines are black to bluish-black. Magnesium-infused tourmalines tend to be brown-to-yellow in color. Multicolored crystals reflect a "fluid chemistry" during crystallization.
