Scientists and engineers from the University of Bristol and the UK Atomic Energy Authority (UKAEA) have successfully created the world’s first carbon-14 diamond battery with the potential to power devices for thousands of years.
Several game-changing applications are possible. Bio-compatible diamond batteries can be used in medical devices, such as ocular implants, hearing aids and pacemakers, minimizing the need for replacements and distress to patients.
The batteries could power active radio frequency (RF) tags where there is a need to identify and track devices either on earth or in space, such as spacecraft or payloads, for decades at a time, thus reducing costs and extending operational lifespan.
The battery leverages the radioactive isotope, carbon-14, known for its use in radiocarbon dating, to produce a diamond battery.
The carbon-14 diamond battery works by using the radioactive decay of carbon-14, which has a half-life of 5,700 years, to generate low levels of power. It functions similarly to solar panels, which convert light into electricity, but instead of using light particles (photons), they capture fast-moving electrons from within the diamond structure.
“Our micropower technology can support a whole range of important applications from space technologies and security devices through to medical implants," commented Tom Scott, Professor in Materials at the University of Bristol. "We're excited to be able to explore all of these possibilities, working with partners in industry and research, over the next few years.”
Sarah Clark, Director of Tritium Fuel Cycle at UKAEA, described how diamond batteries offer a safe, sustainable way to provide continuous microwatt levels of power.
"They are an emerging technology that use a manufactured diamond to safely encase small amounts of carbon-14,” she said.
Fatimah Sanni, a Senior Process Engineer at UKAEA, told gizmodo.com that researchers can imagine a future in which diamond batteries are used in almost everything. She listed small satellites, computer chips, remote controls and wrist watches as some day-to-day examples.
Diamond batteries, which have no moving parts and require no maintenance, could potentially replace lithium ion batteries, which are taxing on the environment.

Exactly one year after their relationship became Instagram official, record producer Benny Blanco proposed to songstress Selena Gomez with a marquise-cut diamond in a yellow gold diamond pavé band.
An excited Gomez turned to Instagram last Wednesday to share a close-up look at the ring with her 423 million followers. She posted four pics with the simple caption, "forever begins now."
Blanco seemed to reveal his motivation for picking a marquise diamond via a short video on his own Instagram page, which showed the couple clinking wine glasses to the track of Gomez's 2015 hit song "Good for You." The lyrics go like this: "I’m in my marquise diamonds / I’m a marquise diamond / Could even make that Tiffany jealous.”
Jewelry-industry insiders believe Gomez, 32, and her new 4-plus-carat diamond could launch a new rush for marquise-shaped center stones and relegate the previously popular oval diamonds to second-shelf status.
The marquise cut, featuring an elegant, tapered shape, is known for its flattering effect of making fingers appear longer and more slender.
In one of Gomez's Instagram photos, the singer/actress is sitting on a blanket while admiring her ring on what seems to be a commercial set arranged to look like an outdoor picnic. Fans pointed out the curious product placement of a Taco Bell box along with a Mexican pizza. Is it possible the fast food chain sponsored the proposal? Or maybe Blanco, 36, proposed during the shooting of a Taco Bell commercial.
In December of 2023, Gomez doubled down on the concept of going “Instagram official” by not only confirming her relationship with Blanco via the popular social media platform, but also revealing a diamond-accented “B” ring on the ring finger of her left hand.
Gomez wrote, “He is my absolute everything in my heart.”
At the time of that announcement, Gomez and Blanco had been secretly dating for six months after having worked on a number of music projects together.
During her November 2024 guest appearance on CBS Sunday Morning, Gomez described her relationship with Blanco.
“I’m beyond proud to know that there is someone in the world that deeply cares about every tiny detail about who I am,” she said. “And [to] have someone support me, encourage me, inspire me and motivate me. It brings me joy. And more than anything he’s just my best friend. I’m really, really lucky.”
The comments section of Gomez's engagement post reflects an outpouring of love from a slew of A-listers, none A-listier than her BFF Taylor Swift, who wrote, "yes I will be the flower girl." The quip earned 1.76 million likes.

Welcome to Music Friday when we bring you classic songs with jewelry, gemstones or precious metals in the lyrics or title. Today, we celebrate the 60th anniversary of the release of “Goldfinger,” the title song of one of the all-time great James Bond thrillers.
Many music critics recognize Dame Shirley Bassey's brass-infused, big band rendition of the John Barry-Leslie Bricuss-Anthony Newley composition as the gold standard for all movie soundtracks.
Goldfinger is also often cited as the best film of the Bond franchise. The film borrows its name from Auric Goldfinger, a villain who hatches a plan to increase the value of his own gold holdings by raiding Fort Knox and contaminating the US bullion supply with radiation. He also has a penchant for gilding his victims.
In the song, Bassey describes "the man with the Midas touch."
She sings, “Golden words he will pour in your ear / But his lies can’t disguise what you fear / For a golden girl knows when he’s kissed her / It’s the kiss of death from / Mister Goldfinger / Pretty girl beware of this heart of gold / This heart is cold.”
“Goldfinger” presented a challenging recording session for the then-27-year-old Bassey. A frustrating series of retakes due to musical and technical issues forced the session to extend throughout the night. Bassey remembered how composer Barry demanded that the dramatic final note of the song be held for an extended count — seven seconds to be exact.
“I was holding it and holding it,” Bassey said. “I was looking at John Barry and I was going blue in the face, and he’s going, ‘Hold it just one more second.’ When it finished, I nearly passed out.”
“Goldfinger” was an instant global phenomenon — in record stores and at the box office. The single netted Bassey her only Top-10 hit on the US Billboard Hot 100. The song peaked at #8 and charted in seven countries. The movie had a production budget of $3 million and grossed $125 million. It opened officially in the US on December 22, 1964.
Bassey’s remarkable rendition of “Goldfinger” has stood the test of time. In 2008, the single was inducted into the Grammy Hall of Fame, and in 2013, the then-76-year-old Bassey performed the song during the Academy Awards as part of a tribute to the James Bond franchise’s 50th anniversary.
A native of Cardiff, Wales, Bassey went on to record the theme songs for two other James Bond films, including Diamonds Are Forever (1971) and Moonraker (1979). In 2000, she became a Dame in a ceremony at Buckingham Palace. She was honored for her services to the performing arts.
In October of this year, the now 87-year-old Bassey placed more than 80 of her own jewels on the auction block at Sotheby’s Paris to benefit her favorite charities. According to Sotheby’s, every jewel in the sale represented a particular moment in Bassey’s life, as well as iconic performances.
Bassey has always been excited to talk about her life-long love affair with fine jewelry, especially diamonds.
“I fell in love with jewelry when I first discovered natural pearls as an up-and-coming singer, and I bought myself my first string of pearls – the first piece of jewelry I’d ever bought,” Bassey told naturaldiamonds.com. “However, I quickly graduated to my lifelong passion for diamonds, which preceded the recording of ‘Diamonds Are Forever.'”
She explained that she accepted the offer to sing the title track of the 1971 Bond flick because the lyrics “rang true” to her: “Diamonds never lie to me / For when love’s gone, they’ll luster on / Diamonds are forever, forever, forever.”
Please check out the video of Bassey’s memorable live performance of “Goldfinger” at the Royal Albert Hall in 1974. The lyrics are below if you’d like to sing along…
“Goldfinger”
Written by John Barry, Leslie Bricuss and Anthony Newley. Performed by Shirley Bassey.
Goldfinger
He’s the man, the man with the Midas touch
A spider’s touch
Such a cold finger
Beckons you to enter his web of sin
But don’t go in
Golden words he will pour in your ear
But his lies can’t disguise what you fear
For a golden girl knows when he’s kissed her
It’s the kiss of death from
Mister Goldfinger
Pretty girl beware of this heart of gold
This heart is cold
Golden words he will pour in your ear
But his lies can’t disguise what you fear
For a golden girl knows when he’s kissed her
It’s the kiss of death from
Mister Goldfinger
Pretty girl beware of this heart of gold
This heart is cold
He loves only gold
Only gold
He loves gold
He loves only gold
Only gold
He loves gold

An 18-karat white and rose gold turtle pavé set with 112 exceptionally rare Argyle Pink Diamonds, 52 natural white diamonds and two emeralds seems to crawl across the face of The Perth Mint’s latest 3D “Jewelled” solid gold coin.
Priced at $171,220 (AUD $269,000), The Jewelled Turtle of 2024 represents the seventh in a series of highly collectible coins that have included the 2018 Jewelled Phoenix, 2019 Jewelled Dragon, 2020 Jewelled Tiger, 2021 Jewelled Horse, 2022 Jewelled Koi and 2023 Jewelled Snake.
The Perth Mint chose to celebrate sea turtles because they are integral to the cultures of coastal communities around the world, as well as being revered in mythology and folklore as symbols of longevity, wisdom, patience, endurance, protection and healing. For some, the sea turtle is considered to be the sacred creator of Mother Earth.
Designed by coin artist Natasha Muhl, the latest release features a turtle shell rendered in rose gold and pink diamonds, while the turtle's head and limbs are set with white diamond in 18-karat white gold. More white diamonds are set in a ribbon-shaped line symbolizing the sea surface and a single Argyle Pink Diamond is set at the heart of a stylized sun. Muhl used emeralds to represent the turtle's eyes.
“Six of the world's seven species of sea turtles are found in Kimberley waters," Muhl said, "and five of those are known to nest there. They really are special animals to me.”
The pink diamonds used in the coin’s design were sourced at the now-depleted Argyle mine in Western Australia. The mine, which had been the world’s leading source of pink diamonds, was shuttered in November of 2020 after 37 years of operation. Each of the colored diamonds has a color rating of Fancy Intense Vivid Pink and Purplish Pink.
Measuring 61 mm (2.4 inches) across, the proof-quality coin is struck from 10 ounces of 99.99% pure gold. The coin’s reverse artistry includes imagery of corals and reef fish, the inscription THE JEWELLED TURTLE 2024 and The Perth Mint’s special “P125” anniversary mintmark.
The obverse features the effigy of King Charles III, the weight and fineness, the “2500 DOLLARS” monetary denomination, “AUSTRALIA” and the King's name.
In this limited-edition offer, only eight coins will be minted and each one will be made to order.

While zoisite has been known to gemologists since 1805, its most famous blue-violet variety was discovered in 1967 along the foothills of Mount Kilimanjaro in Tanzania by a Maasai tribesman named Jumanne Ngoma.
Ngoma revealed his find to a prospector named Manuel d’Souza, who had the sapphire-like specimens analyzed by the Gemological Institute of America. The results revealed the intense, electric blue gems were a never-before-seen variety of zoisite.
In less than a year, the marketing team at Tiffany was preparing a broad-based advertising campaign to introduce the unique gem to the world — but one large hurdle stood in the way.
Zoisite, pronounced "zow-uh-site," sounded a little too much like "suicide," so the gem was cleverly rebranded as "tanzanite" to honor its country of origin.
The original campaign advertised that tanzanite could now be found in two places — "in Tanzania and at Tiffany's." It was wildly successful and tanzanite soon became a household name.
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.
Interestingly, while other varieties of zoisite — in a range of colors from pink, brown and yellow to green, grey and colorless — are found in Kenya, Norway, Switzerland, Austria, India, Pakistan and the US, the vibrant blue-violet crystals are mined in only one location on earth. The area in Merelani Hills near Arusha, Tanzania, measures just 2km wide by 4km long, and the remaining lifespan of the mine is said to be less than 30 years.
The half-carat zoisite specimens seen in the photo, above, reside in the Smithsonian in Washington, DC, and were gifted to the National Gem Collection by Edward W. Boehm in 2008.
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.
In 2018, Asha Ngoma, the daughter of Jumanne, made a desperate plea to then-Tanzanian President John Magufuli on behalf of her nearly 80-year-old dad, who was ill, partially paralyzed and struggling financially. The President responded in April of that same year with a reward of 100 million shillings (about $44,000) and well-deserved words of praise.
“Mr. Ngoma is a veritable Tanzanian hero,” Magufuli told The Citizen.
The man credited with the discovery of tanzanite passed away less than a year later in January of 2019.

On Thursday, The Pantone Color Institute selected a warm brown hue to be its 2025 Color of the Year. The institute said "Mocha Mousse" nurtures with its suggestion of the delectable quality of cacao, chocolate and coffee, appealing to our desire for comfort.
The fashion community was surprised by the subdued selection, which is less a color and more a state of being. It's a far cry from the vibrant selections of the past, such as 2012's Tangerine Tango, 2018's Ultra Violet and 2023's Viva Magenta.
Each year, Pantone selects a color that captures the global zeitgeist. The selection for 2025, according the color authority, reflects a growing movement by consumers to align more closely with the natural world.
“Sophisticated and lush, yet at the same time an unpretentious classic, Mocha Mousse (PANTONE 17-1230) extends our perceptions of the browns from being humble and grounded to embrace aspirational and luxe," noted Leatrice Eiseman, Executive Director Pantone Color Institute.
Laurie Pressman, the Pantone Color Institute’s vice president, added that Mocha Mousse is inspired by “little treat culture,” which involves embracing life's simple pleasures, such as a cup of coffee or a piece of chocolate.
Mocha Mousse unseats Peach Fuzz, Pantone's 2024 Color of the Year. That color's warm and welcoming embrace was said to convey a message of compassion and empathy.
Consumers looking to accessorize Mocha Mousse fashion in 2025 might consider fine jewelry adorned with brown-family gemstones, such as smoky quartz, brown topaz, brown garnet, brown zircon and even brown diamonds.
Those looking for extra depth and a pop of color might look to Pantone's Mocha Mousse color pairings. Neatly complementing the neutral brown of Mocha Mousse are Tendril Green (think green jade, tourmaline, peridot and malachite), Cornflower Blue (think sapphires, blue topaz, aquamarine, indicolite, blue spinel), Viola Purple (think amethyst, purple sapphire, tanzanite, purple garnet, purple spinel) and Rose Tan (think pink diamonds, pink sapphires, morganite, pink garnet and rose quartz).
Typically, Pantone’s yearly selection influences product development and purchasing decisions in multiple industries, including fashion, home furnishings and industrial design, as well as product packaging and graphic design.
The Pantone Color Institute originally created the Pantone Color of the Year educational program in 1999 to engage the design community and color enthusiasts around the world in a conversation around color.
Here are the Pantone Colors of the Year dating back to 2011…
PANTONE 13-1023 Peach Fuzz (2024)
PANTONE 18-1750 Viva Magenta (2023)
PANTONE 17-3938 Veri Peri (2022)
PANTONE 17-5104 Ultimate Gray (2021)
PANTONE 13-0647 Illuminating (2021)
PANTONE 19-4052 Classic Blue (2020)

One of four surviving pairs of Ruby Slippers worn by Judy Garland in 1939’s The Wizard of Oz just sold at Heritage Auctions for $32.5 million, establishing a new record for the most valuable movie memorabilia ever sold at auction and decimating the previous record holder — the billowing white dress worn by Marilyn Monroe over a subway grate in 1955's The Seven Year Itch — by nearly $27 million.
Saturday's live bidding opened at $1.55 million, and for about 15 minutes bidders in attendance battled with those making offers over the phone. The price quickly ticked up in increments of $1 million until the slippers hit their final price of $28 million and the auction room erupted with applause. With the buyer's premium included, the total price was $32.5 million, nearly 10 times the pre-auction estimate. The buyer has chosen to remain anonymous.
This is a fitting final chapter to the story of "The Traveling Shoes," the name given to this particular pair because they were frequently on the road at exhibitions.
Michael Shaw, a collector and former child actor, had acquired the slippers from Kent Warner, a Hollywood costumer, who discovered them in an MGM warehouse shortly before the famous May 1970 auction that liquidated costumes and props from Hollywood’s Golden Age.
Shaw told The Los Angeles Times in 1988 that when Warner brought him the ruby slippers, “I was so thrilled I literally started crying… I told him that if I never owned another possession, I’d be happy.”
In 2005, the Judy Garland Museum in Grand Rapids, MN, borrowed Shaw’s Ruby Slippers for its annual Judy Garland Festival. It was scheduled as a 10-week exhibition, but on August 28, 2005, someone slipped into the museum after hours, shattered the plexiglass case holding the slippers and stole them, leaving behind only a single red sequin.
“It’s the worst nightmare for me,” Shaw said at the time.
In July 2018, after Shaw feared the slippers had disappeared forever, the FBI and Grand Rapids Police Department recovered the pair during a sting operation.
Earlier this year, Shaw was finally reunited with his treasured Hollywood memorabilia.
“It’s like welcoming back an old friend I haven’t seen in years,” said a teary-eyed Shaw as he stood beside a display of the slippers, along with the federal agents and local authorities who spent almost two decades tracking down the Technicolor treasures.
In May 2023, a federal grand jury had indicted Terry Martin for stealing “an object of cultural heritage” from the museum. Five months later, Martin pleaded guilty. Shortly before sentencing, Martin told the court he’d stolen the shoes because he thought the sequins were genuine rubies.
Unable to sell them on the black market, Martin said he ditched the slippers with someone who had recruited him for the job.
“There is simply no comparison between Judy Garland’s Ruby Slippers and any other piece of Hollywood memorabilia,” said Heritage Auctions' Executive Vice President Maddalena. “The breathtaking result reflects just how important movies and movie memorabilia are to our culture and to collectors. It’s been a privilege for all of us at Heritage to be a part of the slippers’ epic journey over the rainbow and off to a new home.”
Gilbert Adrian, the chief costume designer at Metro-Goldwyn-Mayer, created the ruby slippers for Victor Fleming’s big-screen adaptation of L. Frank Baum’s children’s novel. (The magical slippers were silver in the book, but Adrian reinterpreted them as ruby because this was to be the first feature film shot in Technicolor).
Adrian had intended to use bugle beads to simulate rubies, but when they proved to be too heavy he swapped most of them for 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.
Only four pairs of Ruby Slippers are known to have survived. One pair remains among the most popular attractions at the Smithsonian’s National Museum of American History in Washington, DC.

Welcome to Music Friday when we bring you fun songs with jewelry, gemstones or precious metals in the title or lyrics. Today, rockabilly revivalist Chris Isaak offers sagely dating advice in his 2002 release, “Notice the Ring.”
Isaak’s character is having a great time getting to know a woman he just met at a club. The chemistry is right and this could be the beginning of something special, but Isaak notices what seems to be a diamond ring on the woman’s finger. Is it an engagement ring? A piece of faux jewelry? Or just a sentimental bauble that was handed down from her grandma?
He sings, “I notice the ring, does it mean anything / You don’t gotta fool me if you say it’s only jewelry / I believe you when you slip off the ring, oh baby / It’s got complicated if it’s more than just gold plated / Are you single, does it mean anything?”
While introducing this song at his concerts, Isaak often offers light-hearted advice to the men in the audience.
“When you meet a woman for the first time, it’s important to focus on her hands. Not the whole body, but the hands,” Isaak joked. “Look at the hands and they will tell you so much about a person. Particularly, notice the ring.”
Penned by Isaak, “Notice the Ring” appeared as the eighth track of the artist’s eighth studio album, Always Got Tonight.
The singer-songwriter, musician, actor and former talk show host is best known for his song, “Wicked Game,” which was featured in the 1990 David Lynch-directed film, Wild at Heart. That was just one of many collaborations between the director and the artist.
The son of a forklift operator dad and a potato chip factory worker mom, Isaak was born in Stockton, CA, in 1956. Isaak was the 1974 class valedictorian at Amos Alonzo Stagg High School and earned a bachelor's degree in English and communications at University of the Pacific. Isaak started his first band in 1984 and was signed by Warner Bros. one year later.
Fun Trivia: As an amateur boxer, Isaak had his nose broken seven times, according to Discussions Magazine. At the time, his good looks and combed-back hair earned him the nickname, Elvis.
We hope you enjoy the audio track of Isaak performing “Notice the Ring.” The lyrics are below if you’d like to sing along…
“Notice the Ring”
Written and performed by Chris Isaak.
Long legged
Good looking
You got everything
Slow walking
You come up
Then I notice the ring
I notice the ring
I notice the ring
You’re talking, I’m listening,
But I don’t hear a thing
Is it something he bought you
Or only a ring, oh baby
I notice the ring
Does it mean anything?
You don’t gotta fool me if you say it’s only jewelry
I believe you when you slip off the ring, oh baby
It’s got complicated if it’s more than just gold plated
Are you single, does it mean anything?
I notice the ring
We gotta slow down
She’s laughing, stop worrying
Get in the swing
Heart pounding, I’m wondering
Just what did she mean
I notice the ring
I notice the ring
Say nobody’s waiting
That’s it’s nothing just gold plating
That it really doesn’t mean anything
Say your grandma left it to you
Just all you need to do is tell me that it’s no wedding ring,
Nice diamond
I notice the ring
We gotta slow down
I notice the ring
I notice the ring
I notice the ring
I notice the ring
I notice the ring
I notice the ring
I notice the ring

The eagerly anticipated, star-studded Wicked just had the biggest box office launch of all time for a Broadway adaptation, bringing in $163 million globally during the weekend of November 22. While Wicked is often described as a prequel to 1939's The Wizard of Oz, conspicuously missing from this year's blockbuster release are Dorothy's iconic ruby slippers. Instead, costume designer Paul Tazewell reimagined the shoes in silver, glittering with more than 1,000 crystals in a swirling, tornado-inpired motif.
The choice of silver slippers remains true to L. Frank Baum's original 1900 novel, The Wonderful Wizard of Oz.
Thirty-nine years later, with MGM's big-budget The Wizard of Oz set to film in vibrant Technicolor, screenwriter Noel Langley feared that silver slippers would fall flat against the vivid Yellow Brick Road. According to film lore, the screenwriter tasked chief costume designer Gilbert Adrian with creating ruby slippers for maximize visual impact.
The silver slippers seen in the current release align with the silver ones used in the long-running Broadway production of Wicked, as well as in the novel of the same name penned by Gregory Maguire.
The shoes play an important role in the story-telling as they give Elphaba’s sister, wheelchair-bound Nessarose (later to become the Wicked Witch of the East), the ability to walk. The same shoes give Dorothy the power to return to Kansas.
“I have the heel starting as a tornado of jewels that swirls up and then wraps over the foot, and swirls around the foot,” Tazewell told Women's Wear Daily (WWD). “We also used short socks on Nessarose when she’s wearing the shoes, which is how we see them on Dorothy in ‘The Wizard of Oz.'”
Tazewell told WWD that the shoes were 3D printed and then hand-jeweled with 1,165 Preciosa crystals. As with Dorothy's ruby slippers, a number of versions were fabricated.
Dorothy’s Ruby Slippers in the 1939 film were originally adorned with the bugle beads that prop designers used to simulate rubies. When they 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 is rimmed in 46 rhinestones, surrounding 42 bugle beads and three larger rectangular faux jewels, according to Footwear News.
Tazewell told WWD that he wanted the shoes to resonate as a piece of jewelry, seeking inspiration from the design of crowns, such as the Boucheron Wave Tiara made in 1910.
“I was looking at the movement of those wave shapes… but I really just sank into the world of spirals because that seemed to be the best way to represent the most whimsical shoe that I could," he said.
The spiral motif is a nod to the tornado that swept Dorothy out of Kansas and into the Land of Oz.
Entertainment Weekly pointed to an Easter Egg in the new release. During the "Popular" number, Glinda (Ariana Grande) selects clothes and shoes from her wardrobe as options for Elphaba (Cynthia Erivo) to wear. The first item is a sparkly pair of ruby red heels, which Elphaba rejects.
It is rumored that the silver slippers will have an even more prominent role in the second half of Wicked, which is set to release a year from now.
In an interesting turn of events, one of the five known pairs of Ruby Slippers to have survived the 1939 production will be sold this Saturday via Heritage Auctions. The current online bid is $1.15 million ($1.43 million including the buyer's premium).

About 50 million years ago, continental drift sent the Indian subcontinent crashing into the Asian continent causing the rise of the Himalayan mountain range. The colossal collision also created a geological environment of heat and pressure perfect for the formation of precious stones, such as rubies, sapphires, jade, spinel, and the rarest of all gemstones, kyawthuite.
Kyawthuite is so rare that only one specimen exists in the whole world. Reddish-orange in color and weighing 1.61 carats, the faceted gem currently resides in the Natural History Museum of Los Angeles County.
The rough kyawthuite crystal was presumed to be amber or topaz when it was discovered in 2010 by sapphire hunters in a stream bed near the gem-rich area of Mogok, Myanmar. But, Dr. Kyaw Thu, a Burmese mineralogist-petrologist-gemologist with a Ph.D. from Yangon University, had a hunch this stone was unique when he acquired it at the Chaung-gyi market.
The International Mineralogical Association confirmed that the mineral was unlike any of the other 6,000 identified minerals in its database and officially recognized kyawthuite as a new mineral in 2015.
Named after Dr. Thu, kyawthuite (pronounced cha-too-ite) is extraordinarily dense (eight times the density of water and double the density of ruby). Its high density is attributed to bismuth, one of the three main elements that make up the chemical formula of the stone. The other two elements are antimony and oxygen, with a trace of tantalum.
Gemologists have wondered out loud why kyawthuite could exist in only one place on the planet. While bismuth and antimony are rare metals, they are not impossibly rare. Yet, if kyawthuite's formula has manifested outside of Mogok, those crystals have yet to be unearthed.
