Faberge, one of the world’s most recognized fine artist jewelers, have unveiled a new creation of their iconic Imperial Eggs. The lucky attendees of last week’s Doha Watch and Jewellery Exhibition in Qatar witnessed the first debut of the extraordinary masterpiece: the $2 million Pearl Egg.

Using a combination of white and yellow gold, the meticulously crafted egg features a total of 139 natural white pearls, gleams with a mother-of-pearl finish and adorned with over 3,300 diamonds and hand-carved rock quartz. The centerpiece is an incredibly rare, unique 12.17-carat natural grey pearl sourced from the Arabian Gulf. To reveal it, the outer egg shell is rotated on the base which allows the six sides to flower open simultaneously to reveal the treasure; reminiscent of how an oyster opens to reveal its’ cultured pearl.

The House of Faberge collaborated with the Al-Fardan family to create this egg in honor of the upcoming centenary marking the last Imperial Egg ever made. A renowned pearl collector and connouisseur, Hussain Ibrahim Al-Fardan personally hand-selected each pearl from his family’s collection to be used in making the Pearl Egg.

The Pearl Egg is the first imperial class egg made in almost a century – the last imperial class egg was created in 1917, under the supervision of Peter Carl Faberge himself. The Karelian Birch, also referred to as the “Birch Egg”, was commissioned by the last Tsar of Russia Nicholas II, intended as an Easter gift to his mother, the Empress Maria Feodorovna. The February Revolution began before the egg could be delivered, signalling the end of the imperial era of Russia and subsequently, Faberge’s eggs.

The Letseng mine in the small Kingdom of Lesotho, South Africa has just uncovered another massive diamond rough: a 198-carat stone, roughly the size of a large letseng 198 caratstrawberry.

A diamond over 100 carats is rare enough – with only about 10 to 15 found each year worldwide – but a rough that is nearly 200 carats is an exceedingly rare find. A stone of this size is expected to yield a polished diamond around 100 carats, or half the weight of the rough it originated from.

Even though the stone’s size is impressive, it is not even close to being the largest ever uncovered from the Letseng mine. In fact, the Letseng mine is well-known for churning out large, quality rough over the years, and has the highest price per carat production of all the mines in the world. Some of the largest include the Letseng mineLesotho Promise, the 15th largest diamond in the world at 603 carats; the Letseng Legacy at 493 carats, and the Leseli La Letseng at 478 carats which are 18th and 20th largest respectively.

What makes this rough even more valuable is its’ designation of Type IIa, which constitutes less than 2% of all natural diamonds. Type IIa diamonds have no measurable nitrogen impurities, making them chemically pure. This not only gives them exceptional optical transparency, but also a high likelihood of achieving a colorless (D-E-F) grade and a high clarity grade. Officials from Gem Diamonds Ltd, which own the majority stake in the Letseng mine, confirmed this after inspection of the stone noting it as “an exceptional white, high-quality diamond that displays no fluorescence”.

Martin Potts, a London-based mining analyst has estimated the 198 carat stone to fetch somewhere between $12 to $15 million.

After one month and 64 soccer matches played, and it is Germany who achieves the coveted title of FIFA 2014 World Champions. Coming into the tournament as #2 ranked in the world, they captured the World Cup Trophy after scoring 1-0 in overtime in the exciting final game with Argentina.jules rimet trophy

The trophy comes as the second redesign in all of FIFA’s history. The original trophy – named the Jules Rimet Cup after the former FIFA president – was a miniature statue of Nike, the Greek goddess of victory. The body was forged in sterling silver and plated over in pure 24K gold, which stood on a base of carved blue lapis lazuli. FIFA regulations at that time stipulated that any country that wins three times would be awarded the Cup permanently; just that happened in 1970, the year that Brazil won their 3rd championship and took the cup home. Unfortunately, in 1983 the cup was stolen in Rio de Janeiro and has never been seen again.

The current trophy has thus been used since 1974, but no longer carries the possibility of being owned by any one country as it remains the permanent possession of FIFA.

fifa trophySilvio Gazzaniga, the Italian creator of the current trophy, describes the depiction as thus: “The lines spring out from the base, rising in spirals, stretching out to receive the world. From the remarkable dynamic tensions of the compact body of the sculpture rise the figures of two athletes at the stirring moment of victory.”

According to FIFA’s official website, the trophy stands at over 36cm tall and made of a whopping 6.175kg of 18 karat yellow gold, which is worth approximately $175,000. The German team will be taking home a gold-plated replica of the trophy, while the actual trophy will remain at FIFA headquarters to only be used at the official ceremonies.

christies green diamond

christies green diamond

A 6.13-carat fancy intense green diamond set a new per-carat record when it sold at Christie’s on May 27 for a whopping $3.6 million, or $594,510 per carat. The square cushion cut diamond is the center of a rose gold halo style ring, accentuated by natural pink diamonds.

Next to red, green is the rarest of colors found in natural diamonds. For most colored diamonds, the color comes from trace amounts of mineral impurities or extreme pressure conditions while the diamond was forming. The tight chemical structure makes it very difficult for any impurities to enter, which is why colored diamonds are exceedingly rare. Small amounts of boron in the crystal lattice structure of a diamond, for example, will impart a blue hue; same goes with nitrogen for yellow, and hydrogen for violet. What gives a diamond a green hue however, is the presence of natural radiation over millions of years. Because the radiation exposure is an external force rather than internal force (such as mineral impurities and lattice defects), it acts on the surface only. As a result, green diamonds are not green all the way through; the color is concentrated on the outer layers and tends to be weakly saturated. That is why a fancy intense green diamond, especially one of a size like this one, is almost a once-in-a-lifetime find.

This spectacular diamond joins the ranks of other recently sold, record-breaking gems at Christie’s. At their Geneva auction just last month, there were three record-breakers alone. They include ‘The Blue’, a fancy vivid blue pear shaped diamond weighing over 13 carats, a 76.5 carat light pink square-cut diamond that sold for $10.2 million, and the ‘Ocean Dream’ – a 5.5 carat, vivid blue-green diamond that went for $8.8million.

jennymcJenny McCarthy is definitely not one to shy away from media! She shocked over 3 million viewers last Wednesday on live television via her morning talk show, The View by showing off a huge yellow sapphire and diamond ring and announcing her recent engagement to singer Donnie Wahlberg.

The former model, actress, one-time author and current co-host of The View was immeasurably ecstatic, jumping up and hugging co-hosts Barbara Walters and Sherri Shepherd. A slideshow of pictures of the happy couple played across the screen as Wahlberg made a surprise appearance from backstage, coming up to hug his sweetheart.

McCarthy’s bubbly and vivacious personality seems to match her engagement ring perfectly: a square brilliant cut yellow sapphire, surrounded by a halo of white diamonds set in a split shank pave white gold band. Known to be a spiritual person, she may have chosen a bright yellow stone to elicit inspiration, creativity, and optimism.jennymc

The actress and TV personality describes how Wahlberg had enlisted the help of her 11-year-old son, Evan, with the proposal. While sitting on the couch at their shared home, Evan brought out a card that said “Will” and handed it to her. He walked back into the other room, coming back with “You”. He returned a third time with a card meant to say “Marry” but spelled “Mary”. McCarthy was in laughter and tears before Donnie came out the last time, wearing a shirt imprinted, “Me?” and got down on one knee.

“Of course, I said ‘Yes,'” she related. “In that moment Evan yelled, ‘I have another dad!’ and it made all of us cry.”

McCarthy began dating the New Kids on The Block singer in May of last year. The pair plan to tie the knot sometime in August 2015.

wreathWe’ve seen many seemingly ordinary items bedazzled into creations of jewelry art: diamond studded shoes by Stuart Weitzman, Victoria’s Secret Fantasy Bras, and even Lady Gaga’s golden wheelchair chariot… but this is the first time expensive jewels are combined with Finnish flora to create a Christmas wreath.

Created by floral designer Pasi Jokinen-Carter, it takes the place as the most expensive wreath ever designed. With 32 diamonds and 16 rubies totalling 138 carats, the creation is priced at $4.6 million. Resting among the elaborate and rare greenery that includes Helleborus flower buds, hand-curled eucalyptus leaves, and blue Hedera berries, the gems add an unmistakable luxurious touch without overwhelming – they create a nice visual contrast with a little pop of color. Twenty-two loose round brilliant hellediamonds are nestled in the petals of one of the Helleborus flowers, and another cradles a 3.03 carat fancy yellow diamond. The largest gem in the wreath is a 17.49 carat ruby.

“I am passionate about my craft and this recent invitation to create an exclusive wreath, using natural materials and diamonds, has been an exciting and exceptional project,” says Jokinen-Carter. The wreath takes about a week to create, with most of the greenery and flowers sourced from his own backyard. All of the gems can be easily dismantled after the holidays, where they may find new (more permanent!) homes in jewelry pieces.

CitrineWith its range in color from sunny yellow to bronze deep orange hues, what better stone to represent the falling leaves of autumn than citrine? One of the official birthstones of November, citrine is a member of the mineral family quartz.

Currently the world’s largest faceted citrine resides in the “Special Exhibit Gems” of the Art Natura museum in Spain, a natural science museum that is home to an extensive collection of colored gemstones. Known as “The Malaga” in tribute of its host city, this oval shaped gem is an enormous 20,200 carats – equivalent to 4 kilos! It neighbors another gemstone of gigantic proportions: the “Eldorado”, a 31,000 carat imperial topaz which also happens to be the other birthstone of November.

Despite its size, “Malaga” has very minor imperfections and is considered nearly flawless. Along with its exceptional color, even distribution, transparency and purity, “Malaga” is truly a world-class gem. Citrine crystals that are found usually measure only a few cm across, and the ones that are larger in size generally lack in quality and are used for decorative purposes rather than jewelry.

The rough that formed “Malaga” was originally discovered in 1990 in Brazil. Due to the complications of the process of cutting and polishing a stone this large, the rough was left untouched for nearly two decades until 2009 when a team of gem cutters took on the challenge. With all of the special considerations needed for a stone of this size, it took over a year to bring to its polished form.

Brazil is the largest producer of the world’s supply of citrines; other important sources include Bolivia, United States, and Madagascar.

kimberly diamondThe New York Museum of Natural History is having an exhibition for the rare 19th century 55 carat diamond that was once part of the Russian Crown Jewels.

The stone is named “Kimberley Diamond” after the Kimberley Mine where it was discovered in South Africa in 1868. It had been cut from a 490 carat crystal. In 1921 it turned into a 70 carat gem and later in 1958 was re-cut and improved for brilliance and proportions.  In the re-cutting process the stone lost some weight 14.92 carats. Now weighing 55.09 carats it was valued at $500,000 but is probably worth considerably more now.

Kimberly Diamond has been perfected to a champagne coloured, emerald cut, rectangular flawless diamond. It is about 1.25 inches in length. It has been described as a “cape diamond” which is an Old World term meaning “deep colour.”

In order a diamond to survive the Earth’s surface it has to get there really fast this stone got a ride on magma. Magma starts very deep in the earth and moves towards the surface at 35-40 km/h. During a volcanic eruption the magma creates bubbles like champagne and can reach speeds up to Mach 2 (twice the speed of sound).

Diamonds were first found along rivers where people would look for gold. In the 1870’s lots of diamonds were found at the bottom of rivers and streams in South Africa. They would follow the river upstream and find a grey blue rock which contained a diamond. Now days a gem the size of the Kimberley diamond wouldn’t survive in modern mining techniques it would be crushed in the process.

The diamond will be on display with “Patricia Emerald” and “The Star of India.” Patricia Emerald is a 632 carat 12 sided emerald crystal from Columbia. The Star of India is the world’s largest gem quality blue star sapphire it is 526 carats in weight and is 2 billion years old!

Kimberly Diamond is on loan from Bruce T. Stuart. The stones will be added to the Morgan Memorial hall of Gems and is on display in the NYC museum through to June 2014.

cheapsidehoardfullA treasure that was uncovered 100 years ago by a workman is going to now be on display for the first time next fall in the Museum of London.  The entire chest called the Cheapside Hoard which includes hundreds of gold and gem studded Tudor and Jacobean jewellery.  There are many questions and possible murder mystery tales surrounding this jewellery which makes its value more than just its weight in gold. It also can tell us about the life during this time in London a period from between 1558 to 1625. Some questions that arise are whose jewels were these? Why was it hidden? Why hasn’t it ever been claimed?

It was first discovered in 1912 when it was buried in a cellar on Cheapside in the City of London.  A workman’s pickaxe smashed through the brick floor more than a century ago and it was left forgotten. When an old house was being demolished on Cheapside the hoard was found and remains priceless.

Swan

“Nothing in the world comes close,” said Museum of London curator Hazel Forsyth. He has been studying the pieces for a long time now. Some of the jewelry includes necklaces, rings, brooches, chains, pearls, rubies, fan holders, scent bottles and two carved gems dating back 1,300 years ago. The most delicate of items are fine gold enamel chains with gems on them up to two meters long they were stitched on gowns and hung from collar to waist as a dazzling display. “This collection has been misunderstood and misinterpreted, dismissed as jewelry for the merchant classes,” Forsyth said. “But at this date the merchants were among the wealthiest people in the land; they had far more disposable wealth than the aristocracy.” Along with the massive rubies, and pearls the size of acorns there are sapphires, emeralds and some fake stones made of quartz crystal which have been dyed and carved to look like precious gems.

New research of a specific gem known as “The Stafford Intaglio”, an oval shaped piece of engraved cornelian, suggest the time it was buried between 1640 and 1666.  The engraved piece is a badge of Stafford with a swan and a wreath, there was only one Viscount Stafford by the name of William Howard in 1640.

broochTwo other pieces from the Cheapside Hoard is a salamander shaped brooch set with Colombian emeralds and table cut diamonds from India. The other is a gold enamel ring set with moonstone and engraved with a frog.

Another extremely rare piece is a hexagonal emerald watch, one of the most unusual and decadent pieces found, one of a kind no other in its era had ever been recorded.

All these jewels will be displayed together they are the single most important knowledge of early modern jewelry worldwide.

DiamondsThe short answer is yes, they can – and it’s not that uncommon.

Diamonds are the hardest material on Earth, however that doesn’t make them indestructible. To understand how and why they chip, we must first separate the concepts of hardness and toughness. These two terms are often confused for one another, but they are not related in any way. Hardness essentially is a measure of how resistant a substance is to being scratched. Hardness depends on the strength of bonds between atoms in the crystal, and also can vary depending on the direction (along the crystal planes) in which this property is measured. This is why, although much less likely, diamonds can be scratched; and they most definitely can be scratched when coming in contact with other diamonds.

Toughness is the measurement of the ability of a material to resist fracturing, breaking, chipping, or cracking in general. The toughness scale ranges from: Exceptional, Excellent, Good, Fair, to Poor, in which diamond only ranks at a Good. A diamond has a cubic crystal matrix, in which there are four perfect cleavage directions. A cleavage direction can be described as a series of side-by-side straight grains running in one direction, such as the graining on a piece of wood. It is a plane of weakness in the molecular crystal of the diamond. Due to these points of weakness in the diamond structure, it is very possible for a diamond to chip and fracture in everyday wear and tear – it wouldn’t necessarily need a big impact for a diamond to chip, only enough of an impact at the right angle.

The shape of a diamond also factors into how likely it is to chip. Acute angles are much more chip-prone than obtuse angles. For example, in round diamonds the areas most likely to chip would be along the girdle edge or the culet (if pointed). However when round diamonds are set in a piece of jewelry the culet is almost always protected, so it is more common to see chips occur on the girdle. For fancy-shapes with pointed girdle edges, the risk of chipping increases. Princess, Marquise, Pear, Heart and to a slightly lesser extent Emerald and Radiant have a higher percentage of damage on the pointed girdle edge. This is why they are always set with prongs protecting the sharp edges.
