German museums might want to start beefing up their security. In late April, a group of thieves stole the world’s largest gold coin from the Bode Museum in Berlin—somehow going undetected as they made off with the 221-pound chunk of change. Now, another German institution has been hit by thievery. As the Associated Press reports, a diamond-encrusted tiara was recently pilfered from the Badisches Landesmuesum in the city of Karlsruhe.

The gold and platinum tiara is adorned with 367 diamonds and has been valued at about $1.31 million. It was locked up in a cabinet in the museum’s throne room prior to the theft, which was discovered on April 29.

The tiara once belonged to Grand Duchess Hilda von Baden, according to The Columbus Dispatch. She was married to Grand Duke Friedrich II, who ascended to the throne in 1907 and ruled over the territory of Baden. A statement from the Badisches Landesmuesum says that the headpiece may have been crafted for the occasion of Friedrich II’s coronation. The couple’s reign, however, was short-lived: Friedrich II was forced to abdicate in 1918, after Germany’s defeat in WWI.

Baden-Wuerttemberg criminal police said they are now looking for witnesses who may have seen something fishy around the time of the theft.

The Foxfire Diamond Bedazzles as Smithsonian's Newest Rock Star

The largest gem-quality diamond ever found in North America is on display at the Smithsonian for three months in its rough, uncut state. 

It's a really unusual chance for people to see this rare diamond,” says Jeffrey Post, curator of the National Gem and Mineral Collection at the Smithsonian's National Museum of Natural History. “It isn't something that happens very often. This may be the only chance in your life to see such a thing.”

Diamonds tend to be highly concentrated in small areas underground where ancient volcanic eruptions pushed magma upward through tubes. The magma solidified into an igneous rock called kimberlite. Scattered through the kimberlite left within the tube are diamonds that were pushed upwards with the magma.

The 187.63 carat Foxfire diamond was almost discarded when it was unearthed in August 2015 at the Diavik diamond mine, above the Arctic Circle in Canada's Northwest Territories. The mine was not known for large diamonds like the Foxfire, but rather much smaller stones. The chances of a large diamond coming through the sorting system were believed to be so slim that all large stones were assumed to be kimberlite, thus filtered and crushed. The Foxfire diamond could have been crushed, but because of its somewhat elongated shape, it slipped through the sifting screen. 

The name Foxfire pays homage to the aboriginal name for the aurora borealis, which Post says looks like "foxtails swishing away in the sky.” 

In June 2016, Deepak Sheth of Amadena Investments, who trades in historic or unique stones, purchased the uncut diamond at auction (the exact price has not been publicly disclosed) and then did an unusual thing. He allowed the Smithsonian's scientists to borrow it. 

“In some way, it's like diamonds are like meteorites from deep in the earth,” Post says.

Most diamonds appear to have been created between one and three billion years ago roughly a hundred miles beneath the surface of the Earth. Diamonds can help geologists understand Earth's history, says Post.

During past volcanic eruptions, “diamonds were brought to the surface, giving us a glimpse into a part of the Earth we can't otherwise study,” Post says.

In order to find out more about the Foxfire diamond's composition, Post exposed the uncut gemstone to different types of light and used a spectrograph to see how the various elements in the diamond were reflecting the light. A funny thing was discovered along the way.

“One of the interesting properties of this diamond is that if you go in a dark room and turn on a black light, it glows bright blue. It lights up the room,” Post says. “There are a number of diamonds that do this, but this does so quite a lot. This happens through trace amounts of nitrogen. By doing spectral analysis of that light, we can tell how much nitrogen might be there.”

It gets weirder.

“What is unusual, is that when you turn the light off [the diamond] continues to glow. First a deep orange color and then it fades to a creamy white glow. So that phosphorescence can tell us something about how that diamond was formed. . . . It gives us this interesting insight into its history that we wouldn't get just by looking at it.”

Larger diamonds have been found elsewhere in the world. South Africa's enormous Cullinan diamond weighed 3,106.75 carats before it was cut into numerous stones. But diamonds from North America are particularly valued because of their relatively clean provenance. Unlike many African diamonds, the stones that come from Canada's mines are not associated with conflicts or wars. Environmental protection standards are high. The microscopic maple leaves and polar bears etched into each diamond helps ensure that buyers know what they are getting.

This geology allows diamond mines to be relatively compact mining operations that can be restored to a healthy wild condition after mining operations are completed. The Canadian government requires that plans for restoration be made before mining even begins.

“With a diamond mine, it's not like oil where you have to pump it some place,” Post says. “You've got one hole in the ground that is a very well defined area, but the area around it can be pretty well returned [as habitat for wildlife]. This one mine, they are literally mining through a lake. In the end, this thing might very well fill up with water again and just be a deeper lake.”

With the passage of time, the Diavik mine will eventually become that deeper lake and for a brief period, the Foxfire diamond is available for anyone who wants to see it.

“It's a one time opportunity,” Post says.

The Foxfire diamond will be on view in the Harry Winston Gallery next to the Smithsonian's famous Hope Diamond at the National Museum of Natural History through February 16, 2017.

Ron Arad Rocks!

Ron Arad, Hot Ingo, 2016, Earrings, silver & red laser sintered polyamide, edition of 100

24 February - 8 April 2016 Louisa Guinness Gallery will be hosting Ron Arad Rocks!; a solo exhibition of new jewellery by internationally renowned artist, architect and designer Ron Arad. The exhibition will offer unique and editioned works including necklaces, bracelets and earrings made from silicon, laser sintered polyamide, quartz, gold and silver.

 Ron Arad (1951) is among the most respected and influential designers working today, he is celebrated for his fluid, curvaceous style, crafting deceptively simple, highly skilled pieces from materials such as aluminium, bronze and steel. Arad's work cannot be easily categorized as he is constantly reinventing the everyday object, transforming it into something daring, witty and provocative. Bookshelves wind their way up walls, tables curve up corners, chairs unravel like ribbon, all retaining their essential function while questioning their perceived limitations. His penchant for playful but daring designs is also reflected in Ron's jewelry work. 
 
Far from the precious stones the title suggests, Arad's Rocks series are made from solid silicon. Though the silicon is soft and pliable to the touch, each piece appears heavy and dangerously jagged; the effect is of bare shards of glass hanging a breath from the wearer's skin.  Not until the viewer has the piece in their hands are they able to detect Arad's sophisticated manipulation of silicon. Far from smashing and threading glass, he chips away at a plain of prepared silicon, shaving each fragment off. 

NAJA, FREE HAND, 2015
vermeil with amethyst, smoky, rutilated or quartz lens

The impression of opaque or colored glass is created by dropping lengths of colored or graphically patterned silk into the silicon, adding an ingenious layer to the optical illusion. Sculpted by the hands of the maker each work is unique varying in shape, color and form.
 
The Hot Ingo earrings and Hot Ingo Necklace derive from Arad's early experimentation with laser sintered polyamide and rapid prototyping in Not made by hand not made in China launched in Milan over a decade ago. One step in the artist's long exploration of what computers and machines are able to achieve, the necklace and earrings take their name and inspiration from Arad's long standing friend and collaborator Ingo Maurer.
 
"I have always been inspired by Ron's work," says Guinness."I am astonished by his consistent ability to solve practical problems with simplicity, intelligence and aesthetic panache. Take Naja not only beautiful and wearable but an ingenious solution to the middle aged drama of short sightedness."
 
Naja, the final series, is a magnifying glass pendant made of a solid quartz lens, surrounded by a serpentine coil of silver or vermeil. The work is named after the distinctive "be-spectacled" markings on the hood of a Naja cobra. Not only a beautiful object, artwork and jewel, with a typically Aradian twist it can also be used to decipher a cocktail menu.
