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.

Van Cleef & Arpels: Midnight Nuit Lumineuse watch

View fullsize

Van Cleef & Arpels' innovative Midnight Nuit Lumineuse was inspired by the glittering of of the stars. The scene depicted in the watch unfolds against a background of aventurine glass and diamond stars, and various constellations are traced out in the white miniature painting. Then, as if by magic, it lights up in a remarkable way.

While the scene is inspired by the wonders of nature, the watch itself is a marvel of human ingenuity. The illumination is thanks to the use of the piezoelectricity phenomenon. The phenomenon of piezoelectricity has been studied since the 18th century. The term refers to the ability of certain materials to accumulate an electric charge when they are subjected to mechanical stress. This is the first Poetic Complications™ watch that creates a luminous motif illuminating the dial. The Midnight Nuit Lumineuse watch contains a strip of ceramic which, when caused to vibrate by the movement, mechanically generates electrical energy. This is used to power six electroluminescent diodes which – on demand – back-light the six diamonds visible on the dial. I think we can all agree that the effect is magical!

Hemmerle Announces New Jewelry Project

Hemmerle has announced The [AL] Project, a new series of jewelry that explores the unique properties of aluminium through innovative design and exquisite craftsmanship.
 
The collection consists of over 15 pairs of earrings and a brooch. The one-of-a-kind pieces are inspired by eclectic themes such as nature, minimalism and geometry. Intricately crafted in aluminium and paired with gemstones such as diamonds, sapphires, aquamarines and garnets, the creations reflect Hemmerle’s strong visual identity. Aluminium is a metal with a rich history; once the most valuable and sought after material in the world, it went on to become used in almost every aspect of human life. Christian Hemmerle explains;

Aluminium’s natural strength and lightness in weight provided the perfect opportunity for us to experiment further with the metal and celebrate its past splendour. Its malleability enabled us to focus on innovation and create intricate works which are delicate in design yet highly durable, whilst remaining true to our dedication to craftsmanship. Informed by the aesthetic we have defined over several decades, the resulting creations are distinctly Hemmerle but imbued with an element of surprise.

Through a process of anodizing, Hemmerle created aluminium in a variety of hues that complement the natural colors of gemstones. A clematis flower brooch is exquisitely modelled in aluminium, its petals full of purple nuances anodized to match perfectly in colour its diamond and purple sapphire centre. Textured dark red ranunculus flower earrings glisten with diamonds enclosed in their petals, set upside down to give a spiky effect. Vibrant bluebells are studded with sapphires and pink blossom and white lily-of-the-valley sparkle with diamonds. In further works, dark-green tsavorites and deep-blue sapphires are set within electric coloured green and blue frames. In a pair of earrings, pave diamonds are layered with black aluminium min­i­mal­ist, sys­tem­atic geo­met­ric forms.
 
The [AL] Project will be previewed at TEFAF Maastricht, 11 – 20 March 2016.  A limited edition book will be published to celebrate the pieces.

Hemmerle is also participating in Beauty - Cooper Hewitt Design Triennial at the Cooper Hewitt, Smithsonian Design Museum in New York between 12 February – 21 August, 2016.

Hemmerle is a fourth generation family run jeweler at the vanguard of contemporary design. Founded in 1893, each jewel conceived is handcrafted and layered with cultural references; they are as original as a work of art with a design aesthetic of powerfully audacious modernity. Today, Christian Hemmerle runs the business with his wife Yasmin and parents Stefan and Sylveli Hemmerle.

Colombia: Treasure Galleon

Originally reported by the BBC:
The wreck of a Spanish ship laden with treasure that was sunk by the British more than 300 years ago has been found off the Colombian coast, says President Juan Manuel Santos.
"Great news! We have found the San Jose galleon," the president tweeted.
The wreck was discovered near the port city of Cartagena.
It has been described as the holy grail of shipwrecks, as the ship was carrying one of the largest amounts of valuables ever to have been lost at sea.
Mr Santos said the cargo was worth at least $1bn (£662m).
The San Jose was carrying gold, silver, gems and jewellery collected in the South American colonies to be shipped to Spain's king to help finance his war of succession against the British when it was sunk in June 1708.
The vessel was attacked by a British warship just outside Cartagena.
Colombian officials would not reveal the precise location of the wreck, but Mr Santos said the find "constitutes one of the greatest - if not the biggest, as some say - discoveries of submerged patrimony in the history of mankind".
He said that a museum would be built in Cartagena to house the ship's treasures. 
Ownership of the wreck has been the subject of a long-running legal row.
The Colombian government did not mention its long-running quarrel with US-based salvage company Sea Search Armada (SSA) over claims to the treasure.
A group now owned by SSA said in 1981 that it had located the area in which the ship sank.
SSA has been claiming billions of dollars for breach of contract from the Colombian government, but in 2011 an American court ruled that the galleon was the property of the Colombian state.

Spanish Claims on the Ship

The Spanish government says it has rights to a sunken Spanish galleon discovered in Colombian waters.
The foreign minister says he is asking for more information about the galleon, the San Jose, found after decades of searching.
The galleon, which was sunk in 1708, belonged to Philip V of Spain. Its discovery was announced on Saturday.
The ship was attacked by the British navy as it set sail for Spain laden, it is believed, with treasure.
Spanish Foreign Minister Jose Garcia-Margallo said Spain wanted an amicable agreement with Colombia over the ship and its contents.
But he said Spain would be prepared to defend its interests at the UN if necessary.
The minister said that there was a UNESCO convention that stipulated that this type of wreck "belonged to the state, was the result of war, and was not a private boat".
"This can be resolved in a friendly way," Mr Garcia-Margallo said.
"They will understand our demands and that we are defending our interests just as we understand their demands and that they are defending their interests."
In 2013 Colombia approved a law to define sunken ships found in its water as national heritage.
Colombia estimates there are up to 1,200 such wrecks in its waters.
President Juan Manuel Santos said the cargo of the San Jose could be worth at least $1bn (£662m)
It has been described as the holy grail of shipwrecks, as the vessel was said to be carrying one of the largest amounts of valuables ever to have been lost at sea - gold, silver, gems and jewellery collected in the South American colonies to finance the Spanish king's war effort.

Harder than diamond

New Substance Is Harder Than Diamond, Scientists Say
By JONAH BROMWICHDEC. 3, 2015

Researchers at North Carolina State University say they have developed a technique for creating a substance they are calling Q-carbon, which represents a third phase, or distinct form, of carbon alongside graphite and diamond.

The discovery could have many applications, notably in the fields of medicine and industry. But Jay Narayan, the lead scientist on the study, has made one claim about the technique that is certain to turn heads.

“In 15 minutes, we can make a carat of diamonds,” Mr. Narayan said. A carat is 200 milligrams.

The process of creating Q-carbon — which involves concentrating a very short pulse of laser light onto carbon — can produce minuscule synthetic diamond “seeds,” which can yield gems.

Diamonds that have been “grown” by depositing successive layers of carbon atoms on the surface of a thin slice of a natural diamond in an intense plasma field.Borrowing From Solar and Chip Tech to Make Diamonds Faster and CheaperNOV. 11, 2015
While the amount of diamond is tiny compared with the yield of traditional industrial techniques, the process can be carried out at room temperature and air pressure, the researchers say, meaning it could be easier to reproduce on a large scale than other methods, including one that has been drawing interest in Silicon Valley known as chemical vapor deposition.

The technique used to create Q-carbon, which was pioneered over the summer, was described on Monday in the Journal of Applied Physics. A tiny laser beam is trained onto a piece of amorphous carbon for 200 nanoseconds, heating it extremely fast. The spot then cools in a process known as quenching, creating Q-carbon.

It isn’t known whether the substance exists in the natural world, but Mr. Narayan suggested it could be present in the cores of planets.

Wuyi Wang, the director of research and development at the Gemological Institute of America and an expert on diamond geochemistry, said that while he would like to confirm the findings himself, “if they are true, it will be very exciting news for the diamond research community.”

He added that the journal is “quite credible” and he “pretty much trusts what they say.”

André Anders, the editor in chief of the journal, echoed Mr. Wang’s excitement, as well as his note of caution.

“This is one of those ‘wow’ papers,” he said. “I put a sticky note on the manuscript that said ‘pay attention to this one’ before the peer review even happened. But the second thought I have, and this is the scientist in me, is that I’m always skeptical.”

Mr. Narayan described possible uses for Q-carbon in creating synthetic body parts, improving tools like deep-water drills, and producing brighter, longer lasting screens for televisions and cellphones.

Casey Boutwell, who works on commercial licensing for scientific discoveries at the university’s office of technology transfer, said he was bracing for strong interest in the technique. “We don’t know exactly how this can be best applied, and we’re excited to get the market’s input,” he said.

Neil Krishnan, the director of technology platforms at the Swedish industrial toolmaker Sandvik Hyperion, called Mr. Narayan’s discovery “extremely interesting.”

“I still think it’s at a nascent stage for us to consider it a competitive threat per se,” he said. “But it would definitely be a new technology that we’d be interested in.”

But Mr. Narayan and his colleagues say the potential for creating synthetic gemstones pales next to possible applications of Q-carbon, which the researchers said is magnetic, fluorescent and electroconductive.

History's Second Largest Diamond Found

Lucara President and CEO William Lamb said the 1,111-carat diamond workers found Monday at the company’s Karowe Mine is “slightly smaller than a tennis ball.” This picture provided by Lucara shows how big the diamond is when compared to a loupe. The 1,111-carat Type IIa diamond is the second-largest gem-quality diamond ever found. Only the 3,106-carat Cullinan Diamond, which was discovered in January 1905 at the Premier mine in South Africa and later cleaved by Joseph Asscher, is bigger.

Workers recovered the stone in the mine’s south lobe, an area that has produced three 300-carat-plus rough diamonds this year (including a 342-carat stone that Lucara sold in July for $20.5 million). As to estimating the value of this amazing stone Lucara Diamond Corp. President and CEO William Lamb saidthat is is “almost impossible” to estimate a sale price for the stone, or what it could yield in terms of polished diamonds.

Buyer's Beware: Fake Pink Sapphire Discovered after 16 Years

Recently a truly buyer beware story has come out of Delaware where a woman has found out she’d been showing off a fake on her finger for the last 16 years. An expert deemed the pink sapphire in the ring her husband had bought for her birthday was worth only $30, instead of the $12,500 the couple thought.
They couple are now suing the jeweler who sold the diamond-and-sapphire ring to the husband in 1999. They are claiming the husband paid $9,000 just for the stone alone, yet it's value would have been allegedly only $10 according at that time, according to The News Journal.
“I was extremely proud of that ring,” the woman said. “I wore it a lot and got an awful lot of compliments. And all these years, I was wearing that fake. I feel like a fool showing off that ring. I can’t get that out of my head. Here all that excitement and Sam spent all that money, and it’s a fake.”
The husband has sued the business and its owners, seeking $37,000 to replace the ring, plus another $2,500 that he paid in insurance over 15 years. The jewelers had offered to replace the stone, but the woman said she didn’t want another sapphire from them.
The lawsuit in Delaware Court of Common Pleas alleges the business owners engaged in deceptive trade practices and breached their contract to sell a natural pink sapphire.
The jewelers responded to the lawsuit saying the couple’s claim is barred by the statute of limitations, and that the owners extended no warranties to the man when he bought the ring. They say the claim is because of wrongdoing by a Pennsylvania appraiser, and have filed a third-party lawsuit against that company.

This is yet another illustration of the importance of finding and consulting a qualified gemologist-jewelry appraiser at the time of purchase. If you have doubts or are considering a major gemstone purchase please consider a second opinion from a non-biased third party who is an expert in the field of gemstone identification! Take the "beware" out of buyer beware and purchase with confidence. 
You can find qualified gemologist-jewelry appraisers through national organizations such as NAJA.

An 8.52-carat diamond was discovered in Arkansas' Crater of Diamonds State Park

An 8.52-carat diamond was discovered in Arkansas' Crater of Diamonds State Park on Wednesday.

On Wednesday June 24th Crater of Diamonds State Park visitor Bobbie Oskarson of Longmont, Colorado uncovered an 8.25-carat diamond. The stone is the fifth-largest diamond found by a visitor to the state park since the site was established in 1972. 

At first she thought the diamond was a quartz crystal because of its size and shape, but a park staffer confirmed later that it was indeed a diamond.

"Ms. Oskarson and her boyfriend Travis Dillon saw the Crater of Diamonds State Park on an Arkansas highway map while in the nearby town of Hot Springs and decided to visit the park. And what a lucky first visit it was for her!" park interpreter Waymon Cox said in a press release.

Oskarson named her find the Esperanza Diamond, after her niece, and plans to keep the gem.

More than 30 diamonds have been discovered in the park's search area this year. Cox said above-normal rainfall this year is one reason for the frequent finds.

"Rain, plus the regular plowing of the search field by our maintenance staff, increases visitors' chances of finding diamonds in the search area," he said.

More than 75,000 diamonds have been unearthed in the park since the first diamonds were discovered there in 1906.

The largest rough diamond ever discovered in Crater of Diamonds State Park (and the largest ever found in the United States) is the Uncle Sam Diamond, which was found in 1924 and was a hefty 40.23 carats, according to the park website.

Excavation Reveals a 2,000-year-old Natural Pearl Found in Australia

Australian scientists said Wednesday that they have uncovered a "very rare" 2,000-year-old natural sea pearl while excavating a remote coastal Aboriginal site. The pearl is the first found on the continent. 

Australia's University of Wollongong on June 3, 2015: a "very rare" 2,000-year-old natural pearl (the first found on the vast island continent) uncovered while excavating a remote coastal Aboriginal site

Kat Szabo, an associate professor at the University of Wollongong said that archaeologists came across the pearl while excavating the site on the north Kimberley coast of Western Australia.

"Natural pearls are very rare in nature and we certainly -- despite many, many (oyster) shell middens being found in Australia -- we've never found a natural pearl before," Szabo, who specialises in studying shells at archaeological sites, told AFP.

The discovery's location is particularily significant because "the Kimberley coast of Australia is synonymous with pearling, and has been for the better part of the last century, " says Szabo 

The pink-and-gold-coloured pearl is almost completely spherical, and measures five-millimeters in  diameter. Because the pearl was nearly perfect round researchers were able to use a micro CT scan to test its age as well as prove that is was naturally occurring rather than a modern cultured pearl.

Pearl producing oysters have been used in rainmaking ceremonies in indigenous cultures, and their shells have been found in the central desert more than 930 miles away. Archaeologists have known about the rainmaking rituals but were not aware of how far back in history they had been practiced until now.

"Studying the pearl has led us to the study of the layer in which it's found," Szabo said.

"In indigenous terms, that's telling a really interesting story about a cultural tradition to do with pearl shells which we knew historically but we've never been able to prove that it went back into the past." 

The pearl is set to go on display at the Western Australian Maritime Museum in Perth later this month, with details of the find published in the Australian Archaeology journal.

Continuing the westward move of auction houses Doyle will hold its Inaugural West Coast Auction in Beverly Hills on Thursday, May 21, 2015 at 10am. These important sales address an entire demographic that has been ignored in the past by the established Eastern houses. 
The sale of Fine Jewelry will feature exquisite designs by such prestigious makers as Van Cleef & Arpels, Cartier, Bulgari and Tiffany & Co. Comprising over 250 lots, the sale showcases jewelry set with diamonds, colored gemstones and pearls, as well as gold jewelry, fine watches and gentlemen's accessories.
One star of the show will be the dazzling collection of jewelry once owned by film star Mae West, comprising a circa 1950 platinum and diamond bracelet-watch by Fred and a platinum, moonstone and diamond ring.

'Sunrise Ruby' Steals the Show at Sotheby's Auction

The “Sunrise Ruby,” a 25.59-carat untreated pigeon’s blood red-colored stone set a new world auction record for price paid for a ruby on Tuesday at the Sotheby's Geneva sale. The ruby was initially estimated to sell at between $12-$18 million but bidding soared to $30.3 million, demolishing the existing ruby auction record that was held by the $8.6 million sale of the “Graff Ruby.” The ring also set a record for the price paid for a jewel by Cartier. It was sold to an million to an anonymous buyer.
The high price of the ruby heavily contributed to the Sotheby’s Magnificent and Noble Jewels auction which the highest-ever total for any jewelry auction at $160.9 million, deposing the Christie’s November 2014 sale of Magnificent Jewels in Geneva, which totaled $150.2 million.

Also performing well but not meeting pre-sale expectations was the “Historic Pink." The 8.72-carat fancy vivid pink diamond sold for $15.9 million, below its pre-sale high estimate of $18 million.
David Bennett, worldwide chairman of Sotheby’s international jewelry division had this to say about the sale: 
“(The) record result is the reflection of outstanding quality of the pieces in the sale across the board,...The galleries have been brimming with collectors during our worldwide exhibitions, and this translated into lively bidding throughout the sale … with truly global demand for the finest diamonds, gemstones and signed pieces of the very highest order.”

The entirety of the auction results can be viewed at Sotheby's 

Alert from GIA Lab

The Gemological Institute of America has cut off four clients traced to hundreds of diamonds submitted with an undisclosed treatment that improves their color by as much as three grades but fades over time. 

On May 12, 2015 GIA Laboratory sent out notifications about the still-unidentified temporary treatment Tuesday and is asking anyone in the trade with these 424 potentially treated stones to turn them back into the GIA for reexamination. According to the National Jeweler approximately 76 of the 500 already have been reexamined by the GIA.)  The majority of the stones are 1 carat or larger. 

GIA has confirmed that they have terminated the client agreements of the companies linked to the stones. GIA spokesman Stephen Morisseau said the lab “reasonably suspects” that the companies knew the diamonds were treated and did not disclose it.  

The companies are listed online as: E.G.S.D Diamonds Ltd., L.Y.E Diamonds Ltd., Abramov Romok and Yair Matatov.

 The GIA also said it notified the diamond bourses. In a statement issued Wednesday, the Israel Diamond Exchange said it called an emergency meeting of its board of directors upon hearing the news and has “resolved to identify the suspects” and act immediately to “take the needed measures.” 
The lab became aware of this potentially new color treatment when a client purchased one of these diamonds and the treatment began to wear off, leaving him with a diamond that had a much lower color grade than what he had paid for. He returned the stone to GIA for reexamination. It was then that the GIA discovered the treatment and the stone was connected with hundreds of others that had been submitted by the four companies. 
GIA hasn’t drawn any solid conclusions yet, Morisseau said they “reasonably believe” that all of the approximately 500 stones have been treated, but cannot definitively say anything until the lab reexamines them. 
Morisseau said the GIA has not yet identified the treatment but are “actively researching it.” He added that they are monitoring other GIA labs worldwide for similar submissions.
