An eagle-eyed New Jersey police officer earned a bowl of meatballs and high praise for finding a diamond that had popped out of a crossing guard's engagement ring at a Tenafly intersection. What made the find even more remarkable was that the diamond was mixed in with broken glass, gravel, ice and other reflective debris.



A day earlier, crossing guard Kathy Iannantuano had been overcome with grief when she noticed the diamond missing from her engagement ring while she was on duty at the corner of Riveredge Road and Jefferson Avenue last week. Iannantuano's late husband proposed with that ring 52 years ago and it has never left her finger.



"I can't even tell you the feeling that I had," Iannantuano told New York's ABC7. "I can't even talk about it now without getting emotional."

Iannantuano first searched the intersection, then her car, home, jacket and gloves. She and her son returned to her intersection later that evening, but they came up empty.

"Oh, I didn't sleep, let me tell you. It was awful," Iannantuano told ABC7. "It just was like the last part of my husband was gone. Because he's been dead three years and I never took that ring off, never."



Iannantuano proved her point by displaying a deep depression in the base of her ring finger, apparently caused by a ring that was a tad too small for the better part of a half century.

When Iannantuano returned to her job the next day, she was greeted by Officer Louis Smaragdakis, who cheerfully said "Good morning" and then he asked the crossing guard how she was.



"She put her head down and I knew something was wrong," he said.

"It was the wrong question to ask," said Iannantuano. "I started to cry."

She told the officer about the lost diamond and he was eager to help find it, but this would be no easy task.

"There was a motor vehicle accident last week. And there were some glass fragments and shards in the ground," he said. "There was also ice on the ground. Everywhere you looked there was some kind of reflection. So I said to myself, 'There is no way I'm going to find this.'"

Smaragdakis had been scouring the area for about 20 minutes when he decided to check Iannantuano's car one more time.

"I said to Kathy, 'Make sure you unlock the car.' As I stepped forward, for some reason I was looking down on the ground and the diamond was just resting right here," he said, pointing to an area near the curb.

"I swear I didn't believe him," she said. "I just could not believe it. I was hugging [him] and calling him an angel. I told him I'd make him a bowl of meatballs. I mean, I did everything."

"This is what we do," officer Smaragdakis told ABC7. "It's about helping others."

Archaeologists studying the skull of a nun who lived in a German monastery nearly 1,000 years ago were initially baffled by the presence of vivid blue flecks embedded in her teeth. Using X-ray spectroscopy, they were finally able to identify the blue pigment as the gemstone lapis lazuli.



Why would a nun living in the Middle Ages have lapis lazuli layered within the tartar of her teeth? Was she ingesting it as a lapidary medicine, or did it get on her teeth during the course of her life's work?

University of York archaeologist Anita Radini told The Telegraph that the nun was likely an illustrator of lavish medieval religious manuscripts. During that time, artists ground and processed lapis lazuli to make the intense blue pigment ultramarine. It was also common for artists to lick their brushes to get the finest tip possible to complete their detailed work.

The blue pigment was distributed throughout the many layers of plaque on her teeth, suggesting she was an illustrator throughout her life.



Highly prized and considered more valuable than gold, lapis lazuli had a singular source at the time — the remote mountains of Afghanistan.

“Only scribes and painters of exceptional skill would have been entrusted with its use,” Ohio State University historian Alison Beach told The Telegraph. Researchers believe the nun was alive from 997 to 1162 A.D.

The archaeologists, who published their study in the journal Science Advances, believe the presence of lapis lazuli on the nun's teeth highlight two remarkable findings...

First, it was previously believed that monks alone were tasked with illustrating biblical texts. Now it is apparent that women were entrusted with this important and painstaking work.

Second, the presence of lapis lazuli in Dalheim, Germany — 3,000 miles from its source in Afghanistan — reveals routes through the trading metropolises of Islamic Egypt and Byzantine Constantinople were already well established in the year 1100 A.D., according to researchers.

The use of ultramarine in paintings continued well beyond the Middle Ages. It was used by some of the most important artists of the Renaissance and Baroque periods, ending in the early 19th century when chemically identical synthetics became available.



Johannes Vermeer's 1665 painting, “Girl with a Pearl Earring,” is distinguished by a striking depiction of a head scarf using the pigment ultramarine.

The mines of northeast Afghanistan are still the major source of lapis lazuli. Other sources include Russia, Chile, Italy, Mongolia, the U.S. and Canada.

Sports star Tim Tebow popped the question to 2017 Miss Universe Demi-Leigh Nel-Peters with a 7.25-carat diamond solitaire ring at his family's farm in Jacksonville, Fla., this past Wednesday. He reportedly got down on one knee and declared, "This ring is internally flawless… just like you."



According to People magazine, the 31-year-old former NFL quarterback and current New York Mets farmhand toured the picturesque property with the 23-year-old former Miss South Africa, eventually leading her to a bench near the lake. Engraved on the bench was the date they first met.



After Nel-Peters said, "Yes," and Tebow placed the impressive ring on her finger, South African singer-songwriter Matthew Mole stepped out from behind a hay bale to serenade them with a live rendition of Nel-Peters' favorite tune, "The Wedding Song."



To make the surprise even more special, Tebow had arranged for Nel-Peters' family and several friends to be flown in from South Africa so they could participate in the celebration.

Ritani vice president Josh Marion told HollywoodLife.com that the ring features a classic ideal-cut round diamond in an elegant platinum setting. He placed the value of the ring at $600,000 to $700,000.

Tebow had invited Nel-Peters to the farm under the cover story that they were making a belated Christmas visit to his family and surprising his dad with a new truck. Tebow even borrowed a vehicle from a local dealership so the ruse would be more believable.

On Instagram, Nel-Peters shared romantic engagement photos and wrote, "Any dreams I’ve ever had, you’ve exceeded them all! I love you and I can’t wait to spend forever with you! @timtebow." She punctuated the post with emojis of a blue diamond ring and a red heart.

Tebow was equally sentimental, posting similar photos and writing on Instagram, "Thank you for saying YES and making me the happiest man in the world. You’re the love of my life, and I can’t wait to spend the rest of my life with you."

People reported that the couple started dating in the summer of 2018 and that no wedding date has been set.

Welcome to Music Friday when we bring you new song with jewelry, gemstones or precious metals in the title or lyrics. Today, Canadian country music star Dallas Smith finds the girl of his dreams in his brand new release, "Rhinestone World."



In the song, Smith admits that he was "lost on highway, a little dazed and confused," but everything changed when she came along.

Country metaphors bring the story to life as he describes a girl who is unlike all the rest. He compares his new love to a little white church in Mississippi, a red Corvette on a Carolina two lane — and to a rare and precious gem.

"Look at you shine," he sings. "Loving you is like finding a diamond in a rhinestone world."

The song made its debut in November of 2018 and hit #30 on Billboard Canadian Country chart.

A native of British Columbia, the 41-year-old Smith was named Male Artist of the Year at the 2018 Canadian Country Music Awards, where his “Sky Stays This Blue” won Video of the Year. He's set to be the opening act at this summer's Country Thunder Saskatchewan, July 11-14. Other top performers at the event will be Jake Owen, Tim McGraw, Chris Stapleton, Terri Clark, Gord Bamford, Travis Tritt and Steve Earle and the Dukes.

Smith always had a passion for music growing up, but was reluctant to perform in public. As a young adult he finally decided to face his fears and joined a band consisting of some good friends. By the age of 21, the young man who's said to have one of the best voices in country music earned his first record deal.

Please check out the video of Smith performing "Rhinestone World." The lyrics are below if you'd like to sing along...

"Rhinestone World"
Written and performed by Dallas Smith.

See the Sun
Coming up
From the from seat of a greyhound bus
Felt the rain
On the faces
I was standing at the gates of Graceland
Searching for something
Searching for someone
Lost on the highway
A little dazed and confused
But the haze of the road dust
Comes into focus
Every time I look at you

You're a little white church
On a corner in Mississippi
The front porch light that feels like home, girl
Look at you shine
Loving you is like finding
A diamond in a rhinestone world

You're a red Corvette on a Carolina two lane
Lighter in the air to a damn good song
Girl, can't believe you're mine
Loving you is like finding
A diamond in a rhinestone world

You're a diamond in a rhinestone world

Waking up
All alone
Means you might have just been chasing ghosts
And all the glitter fades fast
And a gold rush ain't made to last

You're a little white church
On a corner in Mississippi
A front porch light that feels like home, girl
Look at you shine
Loving you is like finding
A diamond in a rhinestone world

You're a red Corvette on a Carolina two lane
Lighter in the air to a damn good song
Girl, can't believe you're mine
Loving you is like finding
A diamond in a rhinestone world

You're a diamond in a rhinestone world

You're a little white church
On a corner in Mississippi
A front porch light that feels like home, girl
Look at you shine
Loving you is like finding
A diamond in a rhinestone world

You're a red Corvette on a Carolina two lane
Lighter in the air to a damn good song
Girl, can't believe you're mine
Loving you is like finding
A diamond in a rhinestone world

You're a diamond in a rhinestone world

You're a diamond in a rhinestone world

The amount bridal couples spent on their engagement rings surged nearly 56% in 2018, according to Brides' American Wedding Study. The surprising climb — from $5,023 in 2017 to $7,829 in 2018 — may reflect a demand for more ornate setting styles and larger center stones.



The engagement ring stats were part of a broad-based survey that also revealed the cost of an average wedding zoomed to an all-time high of $44,105, as more and more couples sought new ways to personalize and extend their celebrations.

Brides' 2018 survey was designed to reveal key insights into the latest trends, behaviors and spending habits for weddings in America, based on responses from 850 brides-to-be or newly married women.

The Knot, which usually publishes its bridal survey at the end of February, reported in 2018 that the average spent on an engagement ring in 2017 was $5,764, down slightly from $6,163 in 2016. It will be interesting to see if The Knot's new stats will reflect startling upward movement, as well.

"Spending is way up across categories, proving that while couples are doing things their own way, they are still prioritizing celebrating their marriage," said Lisa Gooder, executive director, Brides. "More than ever, couples are savoring the whole process, from engagement to honeymoon and beyond, by celebrating with more events, trips, and professional photos or videos to capture the moments."

The Brides report emphasized these emerging trends: In 2018, 9% of couples took a wedding-moon (pre-wedding trip) together; 31% hosted multi-day wedding weekends (up from 20% in 2017); 39% had a post-reception after-party (up from 20% in 2017); and 14% of brides wore a second look for their after-party (up from 7% in 2017).

The stunning emerald ring that Michelle Yeoh wore in her starring role as Eleanor in the hit movie Crazy Rich Asians made an appearance on the Golden Globes red carpet Sunday, and E!'s Giuliana Rancic was quick to take notice. The ring had generated a buzz this past August when Yeoh revealed it was from her personal jewelry collection.



Fans of the movie know that the ring plays a pivotal role in the storyline. It's worn by Yeoh, who portrays the very stylish, but domineering, family matriarch Eleanor Young. Viewers are introduced to the ring when her son's girlfriend, Rachel (Constance Wu), admires it while the Youngs are preparing dumplings.



Eleanor, at first, disapproves of Rachel's relationship with her son, Nick (Henry Goulding), but later in the film, Nick proposes with the emerald ring, indicating that the matriarch had given her blessing.

The movie's director, Jon M. Chu, had envisioned Eleanor wearing an emerald engagement ring because the green color is strong and regal like the character.

The costume designers fashioned the jewelry to look like the engagement ring John F. Kennedy had given to Jacqueline Lee Bouvier in 1952. But when Yeoh saw that ring for the first time, she told the director that it wouldn't do.

Instead, the 56-year-old actress replaced the underwhelming prop with a ring from her own jewelry box.

Yeoh told Rancic: "This is my own ring. It was such a character in the film, so it had to be instantly recognizable. The color green is about life, prosperity... and with Eleanor, since she's so particular, I knew [this is the] ring that she would wear."

As soon as the actress received confirmation that Crazy Rich Asians had been nominated for a Golden Globe, she knew the emerald ring would be a perfect accessory to pair with her emerald-colored gown at the high-profile event, according to the LA Times.

See Rancic's full interview with Yeoh, below. The ring enters the conversation at the 1:32 mark.

For the second time in five weeks, the New York City Police Department has rescued a diamond engagement ring from a utility grate near Times Square.



The metal grates, which were once famous for consuming spiked heels and small change, are now menacing bridal jewelry at an alarming rate.

The NYPD went as far as to send out this tongue-in-cheek public service announcement via its Twitter page: "PSA: Attention all newly engaged! Please avoid sewer grates at all cost! Thank you."

Back in early December, a British couple became international celebrities after a video of them losing their engagement ring down a utility grate in Times Square went viral.

The couple reportedly flagged down police officers on the night of the incident, but they were not able to access the ring in the darkness. The couple returned to the UK the next day without filing a police report or providing their contact information.

The NYPD was not about to give up the search, however, and detectives were back at the scene the next day, descending into the muck eight feet below the sidewalk to rescue the ring. The NYPD used its Twitter account to locate the couple, and within 24 hours they were found.

Two weeks later the couple was invited back to the U.S. to appear on the Ellen show, where they were not only reunited with their engagement ring, but also got to meet the hero detectives who found it. The show also gifted the couple $10,000 as a wedding gift.

On January 5, the Twitter account for NYPD Midtown North was buzzing with more news about an engagement ring that was rescued from a utility grate at 48th Street and 8th Avenue, just a block from Times Square. The post — which includes a photo of an oval diamond in a halo setting — gives credit for the recovery to the NYPD's Neighborhood Coordinating Officers (NCOs), Emergency Service Unit (ESU) and the Fire Department of New York City (FDNY).

In a tweet that begins with a blue diamond engagement ring emoji, the department wrote: "Ring in the new year & you won’t believe it — it fell down a sewer grate. It’s the first engagement ring we recovered in 2019. NCO’s along with ESU & FDNY were able to retrieve the ring. Sound familiar? Well this time we gave it back at the scene in lieu of the @TheEllenShow."

Unlike the British couple who reveled in their new-found fame, the woman who lost her ring at 48th Street requested to remain anonymous.

InStyle magazine's editor-in-chief Laura Brown raised the bar for engagement ring selfies last week when she posted to her Instagram page an impeccable close-up shot of her new Art Deco-inspired bling. The ring features a round center diamond surrounded by an unusual asymmetrical array of square and rectangular baguettes.



Comedian and writer Brandon Borror-Chappell surprised the Australian-born fashion guru with a marriage proposal while the two vacationed over the holidays with some adorable furry friends in the Land Down Under.



Brown teased the big news in an Instagram post that showed the couple embracing at the Kangaroo Sanctuary in Alice Springs, Australia. The caption read: "What can I say: someone really digs kangaroos. I love you forever, @brandogeoffrey." Prominently seen on the ring finger of her left hand is a diamond engagement ring.

In a post the next day, Brown told her 251,000 Instagram followers how the sanctuary's team played a big role in the surprise proposal. A baby kangaroo and the engagement ring starred in the post.



"And we’re already parents!" she wrote. "This is Vegemite, just rescued by Brolga and Tahnee of @thekangaroosanctuary that morning. We can’t tell you how special these guys are. Kind and gracious and full of love. And also the greatest and sneakiest wingmen for @brandogeoffrey’s proposal. Thank you!"

Bowing to numerous requests for her to post a closeup of the ring, Brown obliged with a beautifully shot selfie.

"And for those of y’all who wanted a closer look at the ring, here it is," Brown wrote on her Instagram page. "Designed by my dear and brilliant mate Stefano Canturi. He is a genius. Am beside myself. Stefano and Patricia, we love you and thank you! @canturi" She punctuated the caption with a red heart emoji.

According to the Aussie designer's Instagram page, Brown's ring is called "Stella" and reflects a style meant to appeal to "modern romantics."

Welcome to Music Friday when we bring you awesome new songs with jewelry, gemstones or precious metals in the title or lyrics. Today, pop star Kelly Clarkson sings about rejuvenating a listless relationship in her 2017 gospel-inspired release, "Heat."



In the song, Clarkson assumes the role of a woman whose marriage is suffering because the passion seems to be gone. Although she still loves her husband, she hammers home the sobering message that the status quo isn't good enough...

She sings, "Baby I deserve it, don't let me down / You used to make me feel like a diamond / Now it don't even seem like you're tryin' / So give me one good reason that I should need you."

In real life, Clarkson and her husband/manager Brandson Blackstock have made a concerted effort to remain fully devoted to each other — no matter what obstacles get in the way.

"[My husband and I] put our kids down and it's like date night every night," she told Entertainment Weekly. "We don't want to be one of those relationships where the passion is gone because you're so tired."

Described by music critic Michael Cragg of The Observer as "pure unadulterated joy," "Heat" was released as the third single from Clarkson's eighth studio album, Meaning of Life. The song peaked at #17 on the U.S. Billboard Hot 100 chart, while the album hit #2 on the U.S. Billboard 200 chart and #4 on the Billboard Canadian Albums chart.

Clarkson, who is currently a coach on The Voice, performed "Heat" on that show in early December and on NBC's New Year's Eve telecast a few days ago.

Born in Ft. Worth, Texas, in 1982, Kelly Brianne Clarkson rose to fame in 2002 after winning the inaugural season of American Idol. Since then, Clarkson has sold more than 25 million albums and 45 million singles worldwide. She has earned three Grammy Awards, three MTV Video Music Awards, four American Music Awards and two Academy of Country Music Awards.

Please check out the video of Clarkson’s live performance of “Heat” as part of her "Nashville Sessions" series at the War Memorial Auditorium in Nashville, Tenn. The lyrics are below if you’d like to sing along…

"Heat"
Written by Andre Davidson, Sean Davidson, Mick Schultz, Jessica Ashley Karpov and Michael Pollack. Performed by Kelly Clarkson.

I'm stumblin' through the darkness
There ain't no sign of a spark here
I'm used to feelin' that fire
You watered down that desire
I put my work in, day in, day out
Baby I deserve it, don't let me down
You used to make me feel like a diamond
Now it don't even seem like you're tryin'
So give me one good reason that I should need you

Come turn this around
(Oh, whoa, oh)
No, no, don't let us down
I need more heat from ya, baby
Make me feel weak for ya, babe
(Oh, whoa, oh)
And I feel alive
(Oh, whoa, oh)
Like my heart's in the wild
I need more heat from ya, baby
Make me feel weak for ya, babe

Keep coolin' down like November
I'm used to feelin' that fever
I wanna dive in you deeper
I put that work in, day in, day out
Baby I deserve it, don't let me down, no
Give me one good reason that I should need you

Come turn this around
(Oh, whoa, oh)
No, no, don't let us down
I need more heat from ya, baby

Make me feel weak for ya, babe
(Oh, whoa, oh)
And I feel alive
(Oh, whoa, oh)
Like my heart's in the wild
I need more heat from ya, baby
Make me feel weak for ya, babe

First discovered in Russia’s Ural Mountains in 1851, the vivid green demantoid garnet is the rarest and most valuable variety of January's birthstone.



Demantoid is derived from the Dutch word for diamond, "demant." The stone owes its impressive diamond-like brilliance to two main factors: A high refractive index and a high dispersion (its ability to separate light into the spectrum of colors). Demantoid, in fact, boasts the highest dispersion rating of all gemstones, including diamond.

The green gem was a favorite of designer Carl Fabergé, who incorporated demantoid into the famous jeweled eggs and other fanciful jewelry he created for the Russian Imperial family. Russian mining of demantoid garnet was suspended after the Bolshevik Revolution in 1917, but finally resumed in the 1970s.

Fine-quality demantoid garnets are rarely found in sizes larger than 2 carats, a fact that makes the examples on this page all the more impressive.

The cushion-cut demantoid, above, is a world-class gemstone and one of the largest and finest faceted demantoids known. The 11.24-carat gem was mined in Russia in the late 1990s and exhibits the highly prized vivid intense emerald-green color. The gem joined the Smithsonian Gem and Mineral Collection in 2011.

The 6.96-carat oval demantoid, below, is from the Green Dragon Mine in Namibia and exhibits a medium dark yellowish-green color. It was purchased on behalf of the Smithsonian in 2014 with funds from the Tiffany & Co. Foundation.



Interestingly, George F. Kunz, who was Tiffany and Co.'s vice president of gemology from 1879 until his death in 1932, was a big fan of demantoid garnets and reportedly purchased all the rough material he could get his hands on.

Demantoid gems are usually high in clarity but may contain distinctive "horsetail" inclusions that seem to spray out from the center of the stone. A beautiful, well-formed inclusion can increase the value of the gemstone considerably, according to the International Color Stone Association.

Demantoid garnet is currently mined in Iran, Namibia, Pakistan, Italy, Madagascar and Canada, but the Russian demantoid continues to set the standard by which all the others are judged.

African-origin demantoid tends to be yellowish-green, olive green or brownish, due to higher concentrations of iron. Russian material, on the other hand, owes its color to chromium and tends to be vivid green.

Other garnet varieties seen in jewelry include pyrope, almandine, andradite, grossularite, hessonite, rhodolite, tsavorite, spessartine and uvarovite.
