A San Francisco-based Greek restaurant chain, which had closed each of its eateries in strict adherence to the city's shelter-in-place order, made a special exception recently and opened one of its stores so a long-time regular could surprise his girlfriend with a proposal in the exact spot where their first date took place five years ago.



Sam Goldstein and Christa Simone are big fans of Souvla, a "fine-fast" restaurant chain specializing in spit-fired meats, Cali-fresh veggies, Greek wines and frozen yogurt in NYC coffee cups.

Goldstein told the dining guide site Eater SF that he had been contemplating a proposal long before the pandemic.

“I’m generally into big crowds," he told the site, "so I was trying to publicly embarrass Christa. But when the world shut down, that became increasingly hard.”

Goldstein's backup plan was to contact the principals of Souvla to see if he could set up a special proposal on the outdoor patio of the chain's NoPa location. That's where the couple's relationship blossomed as they dined on chicken salads and a bottle of rosé.



The love-struck young man was surprised when Souvla owner Charles Bililies quickly agreed to oblige. Not only did he open the shuttered restaurant for the couple, but also had a special sign made for the front window — “Come on in, Christa” — placed rose petals in the corridor leading to the patio and set up a table with sentimental photos, flowers and a bottle of wine.



On Saturday, Goldstein encouraged Simone to take a walk with him through the neighborhood, making sure Souvla was on their route. When the couple passed in front of the restaurant, Simone was surprised to see her name on the sign.



Bililies and his wife, Jen Pelka, greeted the couple and led them to the back patio, where Goldstein popped the question with a diamond ring and Simone said, "Yes."

“We were blown away by how incredibly generous and helpful Charles and Jen were,” Goldstein told Eater. “It just goes to show how kind people can be, even to complete strangers. It was one of those moments that restores your faith in humanity.”

Even though San Francisco allows restaurant take-out service, the Souvla chain has decided to remain closed through the shelter in place in an abundance of caution for the health and safety of its staff.

"We know San Francisco misses Souvla – we do too," the chain's representative told SFGATE. "We'll be reopening soon, in the safest way possible for our team and our guests. We hope everyone is staying happy and healthy, and we can't wait to see our customers again soon!"

Reservations were limited and visitors needed to bring their own tools, but the good news is that Arkansas' field of dreams — the Crater of Diamonds State Park — reopened on Friday, May 22, just in time for the Memorial Day weekend.



The 37½-acre search field in Murfreesboro is actually the eroded surface of an ancient diamond-bearing kimberlite pipe. Treasure hunters test their luck at the only diamond site in the world that's open to the general public.



More than 29,000 diamonds have been found in the crater since it became a state park in 1972.

“We are pleased to be able to welcome people back to search for diamonds at the Crater of Diamonds just in time for the Memorial Day weekend,” said Stacy Hurst, secretary of the Arkansas Department of Parks, Heritage and Tourism. “It is one of the most popular destinations in our system of state parks, and we have had many questions from people who are anxious to again have the opportunity to find and keep their very own gem.”

Due to health concerns related to the COVID-19 pandemic, the popular tourist destination will be limiting attendance and enforcing some restrictions.

The number of daily visitors has been capped at 500, and all of those tickets may be booked online. Be sure to check this site for ticket availability. It's very likely that the daily tickets will be sold-out and walk-up tickets will be unavailable.

Visitors are encouraged to bring their own diamond mining tools, because there are no rentals at this time. Even though prospectors have found plenty of gems on top of the soil, most diamond hunters like to do a little digging. They use a range of simple tools, from small flowerbed trowels to full-size shovels. Some bring their own sifting screens.

The park staff provides complementary identification and registration of diamonds found at the park.



Face coverings will be required for all persons present in the Visitor Center, Diamond Discovery Center, North & South Sluice Pavilions and all four sun shelters. Children under the age of 10 are not required to wear face coverings. Hand sanitizer will be available for guests in the Visitor Center.

To keep a safe distance in the search field, guests/associated groups will be asked to keep a 12-foot distance between other guests/associated groups, unless they are wearing face coverings.

The mining area is now open seven days a week from 8 a.m. to 4 p.m. The Visitor Center closes at 5 p.m. Ticket prices are $10 for adults, $6 for children 6-12, and kids under 6 get to search for free.

In an average year, amateur diamond hunters will find more than 600 diamonds in all sizes, colors and grades.

In 1990, Shirley Strawn discovered a 3.03-carat diamond near the East Drain section of the park. That rough gem was transformed into a world-class, 1.09-carat round brilliant-cut sparkler, and became the first diamond from the Arkansas state park to earn a perfect grade of “Triple Zero” (Ideal cut/D color/Flawless) from the American Gem Society.

The find was so momentous that the State of Arkansas purchased the diamond, now known as the “Strawn-Wagner” diamond, for $34,700 and made it the centerpiece of the park’s special exhibit. There’s even a prominent marker in the East Drain section of the park to show exactly where it was found.

The Washington Nationals unveiled the design of their 2019 World Series rings during a video presentation on Sunday night. Featuring 257 gemstones weighing a total of 23.20 carats, the 14-karat white and yellow gold rings document the team's unlikely road to the championship after starting the season with a 19-31 record.



The team had been enduring a miserable slump when outfielder Gerardo Parra chose "Baby Shark" as his walk-up song. Parra picked the popular children's song because his two-year-old daughter loved it, and so did the fans. The adorable tune — "Baby shark, doo doo doo doo doo doo"— had a way of galvanizing the energy in the stadium and the players used that energy to finish the season 96-69.



As a nod to the song that helped to turn their season around, the Nationals asked ring designer Jostens to include a baby shark holding a yellow gold trophy on the inside of the band. To the right of the shark are the team logos of each of the opponents the Nationals defeated during their postseason journey, along with the results of each series.

The rest of the ring is brimming with symbolism, as well.

The ring top features the team's "W" logo, crafted from 30 custom-cut genuine rubies framed in yellow gold. The number 30 was chosen because that's how many runs the team scored in the four World Series games in which they were victorious.

The logo overlays a ground of 58 pavé-set diamonds, and is circled with the words WORLD CHAMPIONS and 32 custom-cut genuine sapphires. The  number 32 represents the sum total of the team's 2019 walk-off wins (7), shutout wins (13), longest winning streak (8 games), and playoff rounds won (4).

An additional 108 diamonds are featured along the ring top, representing the number of regular season and postseason wins (105), plus one diamond for the World Series Championship, and an additional two diamonds as a nod to the duality of the franchise's history. The Washington Nationals originated as the Montréal Expos. The top and bottom edges of the ring top each feature 12 princess-cut rubies, representing the total number of postseason wins.



On the left side of the ring in raised yellow gold is the player's name. Beneath the player name, also in yellow gold, is the nation's flag waving majestically, along with the 2019 championship year date.

In the foreground, in contrasting white gold, are some of the U.S. capitol's most iconic buildings and monuments, including the Lincoln Memorial, Washington Monument, Capitol building and Jefferson Memorial. The bottom of the ring's left side serves to display the player's number, set in diamonds.

During the postseason, the team's motto was "Stay in the fight." The evolution of that motto is featured on the right side of the ring: "Fight Finished." Below, the stripes of the American flag fill the sky above Nationals Park behind the coveted Commissioner's Trophy, complete with the Nationals wordmark logo.

Also appearing on the right side are four diamonds set upon a star base, as well as a custom-cut, star-shaped ruby. The five stars represent the incredible five elimination games won by the Nationals in the postseason. The four diamonds on the stars represent the four previous National League East titles earned by the Nationals, while the red star signifies their World Series Championship.

The team's mantra of "Go 1-0 Everyday," appears along the ring palm.

In all, the ring features 170 round diamonds (4.20 carats), 31 custom-cut rubies and 24 princess-cut rubies (7.25 carats) and 32 custom-cut genuine sapphires (11.75 carats).

The team voted to receive their rings when they can be physically united. The Nationals had originally planned to host a ring ceremony before the team's second home game on April 4, but the season has been delayed due to the coronavirus.

Welcome to Music Friday when we bring you wonderful tunes with jewelry, gemstones or precious metals in the title or lyrics. Today, Philadelphia R&B legends Boyz II Men sing about a long-lost love in their 2014 release, “Diamond Eyes.”



In this power ballad about a man longing to be reunited with the dream girl of his past, the soulful singers croon, “And then the sun rose, our bodies unfroze / And it turned us both gold / Your diamond eyes glowed, yeah.”

Songwriter Coley O'Toole uses the precious metal reference to symbolize the innocent and exciting “goldenness” of youth, an idea first invoked in the 1923 Robert Frost poem, “Nothing Gold Can Stay." Her diamond eyes connote strength, brilliance and perfection. In the end, the song's protagonist says he will never lose hope that she will be found.

"Diamond Eyes" was the first single released from the group's 12th studio album, Collide. The album reached #6 on the U.S. Billboard Top R&B/Hip-Hop Albums chart and #37 on the U.S. Billboard 200 albums chart.

The four-time Grammy-winning act, which features the sweet harmonies of long-time members Shawn Stockman, Wanya Morris and Nathan Morris, has sold more than 60 million recordings and earned a star on the Hollywood Walk of Fame in 2012. The group was named by the RIAA (Recording Industry Association of America) as the most commercially successful R&B group of all time.

Originally known as Unique Attraction, Boyz II Men was founded in 1985 by friends Nathan Morris and Marc Nelson at the Philadelphia High School for the Creative and Performing Arts. The original group often rehearsed in a school bathroom due to its excellent acoustics.

By the early 1990s, Boyz II Men earned international fame with a series of Top 5 releases, including "Motownphilly" and "It's So Hard to Say Goodbye to Yesterday." The group originated as a quartet, but became a trio when Michael McCary had to leave the group in 2003 due to multiple sclerosis.

In 2017, a section of Broad Street in Philadelphia was renamed “Boyz II Men Boulevard.” That section of Broad Street happens to be the home of the high school where the boys got their start.

Check out the audio clip of Boyz II Men performing “Diamond Eyes.” The lyrics are below if you’d like to sing along...

“Diamond Eyes”
Written by Coley O'Toole. Performed by Boyz II Men.

When we were young, our hearts were strong,
And they beat as one, till the day had come
When I thought that you were gone

And then the sun rose, our bodies unfroze
And it turned us both gold
Your diamond eyes glowed, yeah, ohhhhh

When we were young, our love was strong
We beat as one, till the day had come,
And I thought that you were gone

And then the sun rose, our bodies unfroze
And it turned us both gold
Your diamond eyes glowed, yeah

I would search near and far
Drag the seas and mine the dark,
Search through every place I think you are
I would search near and far
Drag the seas and mine the dark
And never losing hope that you be found, ohhhh

And then the sun rose, our bodies unfroze
And it turned us both gold
Your diamond eyes glowed, yea,
your diamond eyes glowed,
your diamond eyes glowed,
your diamond eyes glowed, ohhhh

Be prepared to be blown away by the next stop on our virtual tour of the Smithsonian’s National Gem Collection. Featured today is an amazing topaz exhibit featuring four stones ranging in size from 12,555 carats to 251,744 carats.



Previous stops on the tour have included the Logan Sapphire, the Dom Pedro aquamarine and the Steamboat tourmaline.

The Janet Annenberg Hooker Hall of Geology, Gems, and Minerals typically hosts more than six million visitors annually. But with all the Smithsonian museums in Washington, DC, temporarily closed to support the effort to contain the spread of COVID-19, we're offering this virtual tour of the hall.



Here's how to navigate to the topaz exhibit.

— First, click on this link… The resulting page will be a gallery called “Geology, Gems & Minerals: Precious Gems 1.” The topaz showcase contains two mammoth crystals and two smaller faceted gems.

(Touch the plus sign to zoom in. Touch the “X” to close the map to get a better view of the gemstones. You may restore the map by clicking the “Second” floor navigation on the top-right of the screen.)



All of the gems in the showcase were sourced in Minas Gerais, Brazil, but the most famous of the four specimens is the colossal cushion-cut American Golden Topaz, the third-largest faceted gemstone in the world. The stone is seen, above, just in front of the little girl.

Tipping the scales at a whopping 22,892 carats (10.09 lbs), the American Golden Topaz was cut by Leon Agee over a period of two years in the late 1980s from a 26-pound stream-rounded cobble owned by Drs. Marie L. and Edgar F. Borgatta.

The final product has 172 facets, a warm honey-gold color and is the size of a honeydew melon, measuring 6.9 x 5.9 x 3.7 inches. The gem was donated to the Smithsonian Institute in 1988.

The tallest stones in the case are the 251,744-carat (111 lbs) Freeman Uncut Topaz and the 158,757-carat (70 lbs) Lindsay Uncut Topaz.



Positioned behind the American Golden Topaz is the fascinating Topaz Sphere, which weighs 12,555-carats (5.54 lbs).

Natural topaz is found in a wide array of warm colors, including brownish-yellow, orange-yellow and reddish-brown. Other topaz colors include white, pale green, blue, gold and pink.

The 28.86-carat D-color diamond that is slated to headline an online auction in June has been named by Christie's as one of the "10 Jewels That Made History — and Changed the Market."



The emerald-cut gem, which is estimated to fetch between $1 million and $2 million at Christie's Jewels Online sale, June 16-30, joined the likes of the $58 million Oppenheimer Blue diamond, the impossibly rare Hancock Red diamond and the world's most famous natural pearl, La Peregrina, in a feature article published last week at Christies.com.

While the 28.86-carat online offering doesn't carry the gravitas of the other gems spotlighted by Christie's, it is very significant in other ways. It is not only the first gem to be offered online with an expected sale price of at least $1 million, but it is also the highest-valued lot ever offered for sale online at Christie’s.

The value of the gem signals a move by the famed auction house to move higher-ticket items to the online sales platform.

“This year has presented unprecedented circumstances, enabling Christie’s new opportunities through our enhanced digital platform,” said Rahul Kadakia, International Head of Jewelry at Christie’s. “Year-over-year, we have seen an increase in online participation and the value threshold for transacting online. Recognizing greater client confidence, we are proud to announce the highest valued lot ever to be offered for sale in our June 2020 Jewels Online auction.”

The D-color diamond boasts a Type IIa purity grading, a designation earned by fewer than 2% of all gem diamonds. Type IIa diamonds have exceptional optical transparency and are the most chemically pure variety of diamonds. They contain no measurable trace of other elements, such as nitrogen, which could alter the color.

The Oppenheimer Blue diamond made Christie's list because it is the most expensive diamond in auction history. It sold for $57.97 million at Christie’s Magnificent Jewels auction in Geneva in May of 2016.

The Hancock Red diamond turned heads when it became the top lot at Christie's New York in April of 1987. Weighing just under 1 carat, the fancy-color purple-red diamond was described as "so rare that experienced diamond dealers would consider themselves extremely lucky to handle more than three in the course of a lifetime." It sold for $880,000 and was, at the time, the most expensive per-carat gemstone ever sold at auction.

With a 500-year history that linked royals, empresses and Hollywood stars, the perfectly pear-shaped La Peregrina natural pearl sold at Christie's New York in 2011 for $11.84 million. It was discovered off the coast of Panama in 1576 and soon became part of the Spanish Crown Jewels. In 1969, actor Richard Burton purchased the gem at auction for his wife, Elizabeth Taylor, on the actress's 37th birthday.

Mounted high above the lobby of the six-star Imperial Palace Saipan are two bejeweled dragons fighting over a flaming pearl. The installation spans more than 60 meters, weighs 40 tons and sparkles with 2.5 million Swarovski crystals.



Czech design firm Lasvit is hoping that its massive undertaking will be recognized by Guinness World Records as the world’s largest pieces of jewelry.



“In this project, we approached the limits of what is both technically and physically possible," noted Leon Jakimič, Lasvit’s founder and president. "Master glassmakers and metalsmiths brought the know-how of hundreds of years of craft tradition while their work was backed by a high-tech design process throughout.”



Jakimič added that the "Saipan Dragons" installation took more than three years to complete and required the expertise of hundreds of technicians from the Czech Republic. It's the company's largest installation to date.



Dragons battling to clutch the elusive pearl is a theme deeply rooted in Chinese mythology. The dragons are divine mythical creatures that symbolize strength, good fortune and transformation, while the pearl — often depicted as a red or white sphere ringed by a fiery blaze — represents wisdom, enlightenment and spiritual essence.

Saipan, which is an island in the western Pacific Ocean about 135 miles northeast of Guam — lies within an active seismic zone. For that reason, the main bearing part of the dragon is made of a stainless-steel truss structure which forms the complete shape and winds throughout the dragon’s body.



The dragons are covered with 13,000 golden scales and 2.5 million Swarovski crystals, which are illuminated by concealed multi-hued LED chips. The dragons have the ability to change color almost instantly.

Check out Lasvit's video, below.

Even though the Hyatt Regency Seattle had to suspend its normal operations due to COVID-19 health concerns, the brand new 45-story hotel at 8th & Howell has been lighting up the sky with love.



Each evening for the past six weeks, the 500-foot-tall, 1260-room landmark — the largest hotel in the city — has been honoring Seattle's first responders and health care workers with a giant heart rendered by lighting individual rooms on the upper floors.

On Thursday, the hotel was happy to oblige a special request by Seattle resident Mitesh Munot, and the lighting configuration became a 21-floor love letter to his girlfriend, Apoorva Prasad.



Right at dusk, the simple heart shape was amended to say "I Love You, AP," with the heart standing in for the word "love."

From the balcony of his home on 2nd Avenue, and with the Hyatt specially lit in the distance, Munot popped the question and Prasad said, "Yes."

Munot told komonews.com how he came up with the idea for the sky-high proposal.

"We can see the beautiful heart sign that the hotel shows with the use of lights in individual rooms," Munot said. "It would probably be the best proposal that I could ever hope for!"

The Hyatt's social media team got into the spirit with an Instagram post that included a photo of the couple and a caption that read, "Love is in the air! Congratulations on tonight’s engagement! Thank you for letting us be a part of your joyous celebration!"

Commenting on the post, Munot, a senior account executive at Amazon, wrote, "@hyattregencyseattle, I can’t thank you enough for making this happen for us! Thank you for giving us a memory we will cherish forever."

Prasad, a senior manager at Amazon, was more than delighted, commenting, "@hyattregencyseattle, your team is incredible! We’ve always loved Hyatt, but you’ll now hold a place in our hearts forever. Thank you!"

The Hyatt Regency officially opened in December of 2018, but was forced to temporarily suspend its normal operations due to COVID-19. The good news is that the hotel was given the green light to start serving customers again on June 1.

Welcome to Music Friday when we bring you chart-topping songs with jewelry, gemstones or precious metals in the title or lyrics. Today, country music duo Keifer and Shawna Thompson of Thompson Square fall in love, get engaged and tie the knot in their semi-autobiographical 2010 hit, "Are You Gonna Kiss Me or Not."



As the song begins, Keifer and Shawna are talking about "everything under the moon" on the roof of her mom's house. He's remembers the intoxicating smell of honeysuckle and her perfume. He also recalls how he was totally panicked — way too shy to make the first move.

Lucky for him, Shawna looks him straight in the eye and asks, "Are you gonna kiss me or not?" Later in the song, Keifer realizes that he wants the relationship to last forever, so he buys a ring and asks for her hand in marriage.

Keifer and Shawna share this key verse: "So I took a chance / Bought a wedding band and I got down on one knee / And you smiled and said to me / Are you gonna kiss me or not? / Are we gonna do this or what? / I think you know I love you a lot / I think we've got a real good shot / Are you gonna kiss me or not?"

Written by Jim Collins and David Lee Murphy, "Are You Gonna Kiss Me or Not" sold more than two million copies and zoomed to #1 on both the Billboard US Hot Country Songs chart and the Billboard Canada Country chart. It was the second single released from Thompson Square's self-titled debut album.

The song also earned Grammy nominations for Best Country Duo/Group Performance and Best Country Song.

Even though Keifer and Shawna didn't write the song, its theme very closely mirrored their own love story.

"The first time we heard it, we fell in love with it," Keifer told The Boot. "We knew we had to record it. It was semi-autobiographical. We just gravitated towards it. We were definitely blessed to get a hold of it."

"We got real lucky with Thompson Square," Collins admitted to The Boot. "They're husband and wife, and it was kind of their story — how they fell in love, even though I don't know if it was exactly up on the roof! When we wrote it, I thought it was a good song. But when I heard their record, the way they cut it, I thought, 'Man! This could be a hit!'"

Born in Miami, OK, Keifer Thompson met his future wife, a native of Chatom, AL, at a singing competition in Nashville, TN. Together, they have produced three albums and placed 10 singles on the Hot Country Songs and Country Airplay charts.

Please check out the video of Thompson Square's live performance from the Bing Lounge in 2013. The lyrics are below if you'd like to sing along...

"Are You Gonna Kiss Me or Not"
Written by David Lee Murphy & Jim Collins. Performed by Thompson Square.

We were sittin' up there on your momma's roof
Talkin' 'bout everything under the moon
With the smell of honeysuckle and your perfume
All I could think about was my next move

Oh, but you were so shy, so was I
Maybe that's why it was so hard to believe
When you smiled and said to me

Are you gonna kiss me or not?
Are we gonna do this or what?
I think you know I like you a lot
But you're 'bout to miss your shot
Are you gonna kiss me or what?

It was the best dang kiss that I ever had
Except for that long one after that
And I knew if I wanted this thing to last
Sooner or later I'd have to ask for your hand

So I took a chance
Bought a wedding band and I got down on one knee
And you smiled and said to me

Are you gonna kiss me or not?
Are we gonna do this or what?
I think you know I love you a lot
I think we've got a real good shot
Are you gonna kiss me or not?

So, we planned it all out for the middle of June
From the wedding cake to the honeymoon
And your momma cried
When you walked down the aisle

When the preacher man said, "Say I do"
I did and you did too, then I lifted that veil
And saw your pretty smile and I said
Are you gonna kiss me or not?

Are we gonna do this or what?
Look at all the love that we got
It ain't never gonna stop
Are you gonna kiss me or not?

Yeah baby, I love you a lot
I really think we've got a shot
Are you gonna kiss me or not?

Lucapa Diamond Company has recovered a 171-carat, gem-quality, white stone at its Lulo alluvial mine in Angola, the same mine that produced the famous 404-carat “4 de Fevereiro” diamond in 2016. That unusual thumb-shaped stone, which nearly ended up as road filler at the mining plant, was eventually cut into a 163-carat emerald-cut stunner that sold at auction for $33.7 million.



The Lulo Diamond Project in Angola, which is owned by Lucapa and its partners — Empresa Nacional de Diamantes E.P. and Rosas & Petalas — has earned a reputation for producing some of the largest and highest-value diamonds in the world.

Since commercial diamond production went online at Lulo in 2015, the mine has generated 15 100-plus-carat diamonds. The 171-carat gem, shown above, is the second 100-plus-carat diamond found in 2020 and the fourth-largest ever recovered at Lulo.

Upstream of the Cacuilo River valley, Lucapa is testing five kimberlite pipes that were likely the hard-rock sources of the exceptional Lulo alluvial diamonds.

“The recovery of this 171-carat, gem-quality, white diamond continues to underpin the potential of the kimberlite-exploration program,” said Lucapa CEO Stephen Wetherall.



Back in 2016, we recounted the wild story of how Angola's most famous diamond was nearly discarded at the Lulo mine by mistake.

On February 4, 2016, as Angola celebrated its national independence day, a thumb-shaped 404-carat rough diamond miraculously found its way through a hole in the sorting screen at the Lulo processing plant because it was oriented vertically, not horizontally. It was aptly named the “4 de Fevereiro” (February 4th in Portuguese) and continues to retain the honor of being the largest diamond ever found in Angola.

Had the gem — which was eventually sold for $16 million — passed through lying flat instead of standing up on edge, it would have been rejected and discarded. It would have likely joined the other rejected, oversized “rocks” Lucapa had collected and used to fill the road beds throughout the Lulo project.

The diamond recovery plant had been configured to capture diamonds up to 280 carats in size. Before that day in February, no rough diamond larger than 278 carats had ever been recovered from the mine.



The 404-carat stone was eventually cut by de Grisogono into a D-flawless, 163-carat emerald-cut stunner that became the centerpiece of an emerald and diamond necklace that fetched $33.7 million at Christie's Geneva in November of 2017.
