The Las Vegas Antique Jewelry & Watch Show moved to the Las Vegas Convention Center in 2017 and will stay there. In 2019, when JCK Las Vegas relocates back to the Sands, AGTA's GemFair Las Vegas will co-locate with the antique show at the convention center.

 New York--The American Gem Trade Association and U.S. Antique Shows have announced that their Las Vegas trade shows will be co-located at the Las Vegas Convention Center beginning in 2019.

The annual Las Vegas Antique Jewelry & Watch Show, which features about 400 exhibitors, moved from the Paris hotel and casino to the Las Vegas Convention Center for the June 2017 event, a relocation it has now made permanent.

The AGTA GemFair Las Vegas event currently is held in the South Pacific and Islander Ballrooms in Mandalay Bay as part of JCK Las Vegas. In 2019, the latter will move back to the Sands Expo and Convention Center.

AGTA and U.S. Antique Shows said the move is designed to enhance their respective markets through an increased access to international buyers and cohesive exhibitions. The move also will provide AGTA with more opportunities to grow and market its GemFair Las Vegas event.

"We carefully researched all facets of this partnership prior to making the decision to align with U.S. Antique Shows at the Las Vegas Convention Center," AGTA CEO Doug Hucker said.

"Through on-going conversations with our members, as well as multiple discussions within the board and in committees, we came to the conclusion that it's time for an evolution for AGTA GemFair Las Vegas. The collaboration with Emerald Expositions was a logical choice; not only is the move mutually beneficial to both of our exhibitors and attendees, but there is also a commonality in the perspectives and goals of each of our organizations."

Gannon Brousseau, Senior Vice President of Emerald Expositions' Jewelry Group, said, "There is tremendous cross-promotional appeal between these two autonomous yet complementary events, and this partnership will ultimately contribute to the prosperity of the entire trade."

Further information about the 2019 events will be released in the coming months.

Meanwhile, JCK Events also announced Wednesday that it will expand its JCK Las Vegas show in 2019 to include a new International Gemstone neighborhood featuring gemstone suppliers from around the globe.

The new neighborhood will run alongside JCK Las Vegas in the Sands Expo and Convention Center. It will be held from June 1 to June 5, 2019, opening one day before JCK.

"Adding an international presence for gemstone suppliers offers a unique, unrivaled opportunity for our vast audience of 20,000-plus domestic and global buyers," said Yancy Weinrich, senior vice president of JCK. "With the move back to the Sands Expo and Convention Center we have the opportunity to offer new experiences and features in an upscale, more buyer-friendly environment."

 Ertswhile specializes in stocking exceptional antique engagement rings, as well as re-purposing older designs into more modern fare. This 0.94-carat transitional cut diamond accented by two smaller transitional cut diamonds needed no re-design. The Art Deco piece in 18-karat yellow gold was created by Tiffany & Co. in 1935 and is similar in style to the ring Prince Harry gave to Meghan Markle to mark their engagement. 

 On Monday, Clarence House announced the engagement of His Royal Highness Prince Harry to Meghan Markle, an American actress currently starring in the USA drama "Suits."

The public and the media were, of course, brimming with questions about the royal and his bride, who sat down for a television interview with the BBC to answer some of them, the most important of which was: Can we see the ring?

"The ring is obviously yellow gold because that's (Meghan's) favorite," said Harry.

Indeed, the only unorthodox element of the classic style, which features a cushion-cut white diamond center stone flanked by two round brilliant diamonds, is its metal.

Yellow gold has been making a comeback in recent years after plummeting in popularity in the late 1990s and early 2000s. But white gold and platinum still overwhelmingly dominate bridal styles, independent retailers told National Jeweler over the course of the 50 Jewelers/50 States store profiles conducted this year, so it was a pleasant surprise to see Markle exert a preference for something classic but unique, perhaps an indicator of future sartorial choices.

And while simply set, the diamonds in the design are noteworthy in that they hold sentimental significance for the couple, Harry explained.

"The main stone itself I sourced from Botswana and the little diamonds on the side are from my mother's jewelry collection to make sure that she's with us on this crazy journey together," he said.

"It's beautiful," Markle interjected, "and he designed it. It's incredible."

Embed from Getty Images

While Markle's predilection for yellow gold, a slight departure from the stylistic norm, is representative of the trend of consumers desiring uniqueness in engagement rings, so is Harry's choice to have a hand in the design of the piece.  

A recent survey from The Knot showed that custom bridal design is an essential aspect of the engagement ring purchase, allowing customers to create something personalized to them (in Harry and Meghan's case, the inclusion of stones from the collection of Harry's mother, Princess Diana, and a stone with a special provenance, as the couple traveled to Botswana during their courtship.)

"I think everything about Harry's thoughtfulness and the inclusion of that and obviously not being able to meet his mom; it's so important to me to know that she's a part of this with us," Markle explained.

Like Markle's engagement ring, this style from romantic and modern designer Jade Trau also feature a cushion-shaped diamond, but with a unique pave diamond bezel setting. Trau designs the piece in yellow, rose or white gold, as well as in platinum. The style starts at $4,700 for a 14-karat gold version.

浪漫的粉紅鑽市場大夯了3、4年，也讓其中三類市場快速擴大：1至2克拉帶偏色粉紅鑽；克拉數小的正色粉紅鑽，如30至50分；30至50分的偏色粉紅鑽。價格因此變得親民許多。通常1克拉的正色粉紅鑽，價值大約台幣400多萬起跳，一般品質的約80萬。如今一些帶偏色，或克拉數不大的粉鑽價格已下降許多，讓人更容易下手。

 

新穎鑲嵌技術 粉紅鑽迅速崛起

　去年秋季起，粉紅鑽市場開始受到越來越多關注與詢問，成交比以往高出2至3倍。其中的改變，最大因素來自彩鑽鑲嵌設計與技術提升，某些傳統鑲嵌工廠引進最新彩鑽鑲嵌技術，可在視覺效果之下，很靈巧的使粉紅鑽顏色與主石發揮最大作用，售價卻相當親民。

 

　改變市場的另一項因素是消費觀念改變，現在消費市場普遍認知，稀有的粉紅鑽即便是一顆不起眼的10分大小都相當珍貴，小顆粉紅鑽市場因此門戶大開。以下將粉紅鑽市場淺析，以回饋忠實的讀者朋友：

 

小顆粉鑽火紅

　火紅的粉紅小鑽市場首推50分大小，新式鑲嵌使之看起來有時甚至比1克拉還大，依裸石顏色的定價大約在百萬台幣左右，比1克拉的彩鑽便宜許多。

 

淺色系性價比高

　以前的「買粉鑽、選正色」的觀念，使買家大多選正色品種，但現在Fancy Light Pink甚至Light Pink也開始走紅。因為新式鑲嵌法不僅令其顏色濃郁又擴大視覺效果，性價比特別高。

 

1.07克拉Very Light Pink淡粉色鑽石戒指，淨度為VS2。

 

 

帶橘色補漲來臨

　偏橘或帶橘的粉鑽一直都被認為是粉紅鑽帶著偏色，但其實橘色正是幫助粉紅鑽提升顏色的好偏色。橘色由紅色與黃色組合而成，紅色對粉紅色有絕對的加分作用，黃色使偏冷色調的粉紅色有暖化修色效果，因此視覺效果有時比正粉色來得更紅而柔和。帶橘的粉紅鑽品種漲勢可期。

 

0.54克拉Fancy Light Orangy Pink淡彩粉橘色鑽石戒指，淨度為VS2。

 

 

非主流色系抬頭

　粉紅鑽的偏色有寒色系與暖色系之分，大多數的寒色系會使粉紅色看起來重些，具有減分作用，如帶灰色的Grayish。暖色系則將對粉紅色有稍稍暖化的作用，例如帶一點點黃的Yellowish。

 

1.47克拉Fancy Light Purplish Pink淡彩紫粉紅色鑽石戒指，淨度為VVS1。

 

 

正色稀有度直線上漲

　在兩極化粉紅鑽市場當中，2至3克拉或更大的濃彩與豔彩級別在市場上難得一見。在供需明顯傾斜之下，售價直線上升，即便是一顆2克拉的Fancy Pink級別，以400萬人民幣的高額售出也比比皆是，3克拉Fancy Intense則接近2千萬人民幣，售價堪比1克拉紅鑽石。

 Zsa Zsa Gabor reportedly said she never met a diamond she didn't like. This Harry Winston diamond rivière necklace was one of the many pieces of jewelry that belonged to the late actress. It's being offered for sale by Bonhams next month. 

 November 17, 2017 New York--An "over-the-top gorgeous" diamond necklace that belonged to one very quotable actress known for her glamorous lifestyle and multiple husbands is going up for auction.

Next month in New York, Bonhams will offer the late Zsa Zsa Gabor's diamond rivière necklace as part of its Dec. 4 Fine Jewelry sale.

Featuring 45 graduated round brilliants totaling 66 carats, the necklace was created by Harry Winston in 1964.

The five central diamonds weigh 8.07, 6.34, 6.33, 5.35 and 4.88 carats, and their quality ranges from F to I color and they are VVS2 clarity.

This image of Zsa Zsa Gabor accompanies the lot. Bonhams said that almost every photograph taken of the late actress shows her "dripping in diamonds."

According to Bonhams, the diamond rivière necklace was a "much-loved piece" in Gabor's collection, and she was photographed wearing it frequently when she was out and about, particularly in the 1960s.

At some point, the necklace was sold; Bonhams said it came to them via a private client, not Gabor's estate.

The necklace is estimated to sell for $1.2 to $1.5 million, though jewels with a known provenance, particularly a celebrity provenance, tend to easily top estimates. (See: the white-glove sale Sotheby's recorded with the jewelry of Vivien Leigh earlier this year and the remarkable Elizabeth Taylor results from Christie's back in 2011.)

One of three sisters born in Hungary to a Jewish family who immigrated to the United States, Gabor's film credits include the 1952 version of "Moulin Rouge." (Her two sisters, Magda and "Green Acres" star Eva, also were actresses and her mother, interestingly, was a jeweler.)

Aside from her acting, she is, perhaps, just as well known for her glamorous lifestyle and her many marriages--Gabor wed a total of nine times, including one very brief marriage that was quickly annulled (and might not have been legal in the first place).

She also was a known lover of jewelry, particularly diamonds, and the combination of the two provided some of the best quotes attributed to her, including "I never hated a man enough to give him his diamonds back," and "Diamonds are a girl's best friend, and dogs are a man's best friend. Now you know which sex has more sense."

"Zsa Zsa Gabor's life was all about 'more is more fabulous,' and when it came to jewelry, it was always 'more, more, more,'" said Susan Abeles, head of jewelry for Bonhams U.S.

She said this particular necklace epitomizes Zsa Zsa to a tee: "It's not just gorgeous, it is over-the-top gorgeous."

Gabor, the last surviving of the three sisters, died last year at the age of 99.

 

Another shot of Gabor's Harry Winston diamond rivière necklace, in which the five largest stones range in size from 8.07 to 4.88 carats.
Previews of the auction featuring the Gabor necklace will take place Nov. 18-20 in Los Angeles, Nov. 22-25 in Hong Kong and Nov. 30 to Dec. 3 in New York.

Bonhams Fine Jewelry sale is scheduled to take place Dec. 4 in New York. Bids can be placed online, via telephone, in writing and in person on the day of the sale.

A diamond of exceptional allure, renowned as the largest flawless D-colour diamond ever to come to auction, set a new world record when it fetched US$34 million at Christie's Magnificent Jewels sale in Geneva.

According to Christie's, the necklace was designed by Fawaz Gruosi, founder of de Grisogono, together with his team of 14 craftsmen. Having created 50 different drafts and devoted over 1,700 hours of effort, a perfect design – an asymmetric necklace with the 163.41-carat, D-colour, flawless, Type IIA diamond at the centre, with 18 emerald-cut diamonds placed on the left side and two rows of pear-shaped emeralds on the right – was made.

Cut from a 404-carat rough, the 163.41-carat diamond was discovered in February 2016 at the Lulo mine in the Lunda Sul Province of Angola.

A further highlight of the Geneva sale was Le Grand Mazarin, a light pink diamond of 19.07 carats, and one of the most famous and important Golconda diamonds in history. It was the final lot of the auction and sold for US$14.5 million.

Le Grand Mazarin is a legendary diamond of historic Royal French provenance, Christie's noted. The stone has been in the collection of four kings, four queens, two emperors and two empresses. This was the first time that the spectacular diamond has been sold at public auction since the famous sale of the French Crown Jewels in 1887.

The Christie's Geneva November series of sales achieved a total of US$145 million, attracting over 4,600 visitors to the Four Seasons Hotel des Bergues. This brings the total for Christie's Geneva auctions in 2017 to US$258.58 million with 27 lots sold for over US$1 million.

  This diamond engagement ring from Sylvie Collection embodies many of the characteristics that were most popular among consumers who took The Knot's 2017 engagement study: made in 18-karat white gold with a 1-carat round diamond and 0.27 carats of pave melee. It retails for $1,690 (not including center stone). 

 November 16, 2017 New York--The Knot's biennial survey on marriage proposals shows that the average engagement ring spend has increased 25 percent since 2011.

According to the wedding planning website's 2017 Jewelry & Engagement Study, which surveyed 14,000 engaged or recently married U.S. brides and grooms, the average amount spent on an engagement ring is now $6,351.

That is up 25 percent from $5,095 in 2011, and is a 6 percent increase from $5,978 in 2015, the last time The Knot conducted this particular survey.

The $6,351 figure is also a couple hundred dollars above the average of $6,163 shared in The Knot's 2016 Real Weddings Study, which surveyed 13,000 couples who got married last year. The results of that survey came out in early 2017.

The Knot does its Jewelry & Engagement Study every other year and releases the results at the end of the year--when the greatest percentage of couples get engaged.

Below are six more points from the 2017 edition of the study, which came out Nov. 9.

1. Those $6,000+ rings are most often set with …
The most popular stone shape for engagement rings was, not shockingly, still round at 52 percent, while the average carat size for the center stone was 1.2 carats. Counting side diamonds and melee, the average total carat weight increases to 1.8.

The most popular setting metal was white gold, cited by 61 percent of respondents.

2. Consumers today do value shopping locally.
A total of 86 percent of respondents said they bought their engagement ring at a brick-and-mortar retailer and, among those, nearly half (45 percent) said they went to a local or independent jeweler.

While this is good news for the smaller brick-and-mortar players, The Knot's survey also showed that the number of men buying engagement rings online is inching up.

The 14 percent of survey-takers who said they bought their engagement ring online is up from 10 percent in 2011.

Better pricing was the main reason for an online engagement ring purchase, cited by 63 percent of survey takers. That was followed by finding the perfect ring while browsing (45 percent), convenience (40 percent) and wanting to build a custom ring (29 percent).

3. They love custom.
Nearly half of survey takers had the engagement ring they bought for their fiancée personalized in some way, whether it was a total custom job (18 percent) or just touches of custom design (27 percent).

Optimum Diamonds LLC in New York paid an undisclosed amount for this 2.11-carat fancy red diamond dubbed the "Argyle Everglow."

 

 November 15, 2017

Melbourne, Australia--Earlier this year, Rio Tinto presented the largest red diamond it's ever recovered from its Argyle mine in Australia.

Now, the miner has announced that the stone is the most valuable diamond in its 33-year tender history.

Optimum Diamonds LLC, a company that specializes in rare, natural fancy color diamonds, bought the 2.11-carat radiant-cut fancy red "Argyle Everglow" for an undisclosed sum. Optimum also won the tender's fifth lot, the "Argyle Liberte," a 0.91-carat violet diamond.

The Argyle Liberte, a 0.91-carat violet diamond, was purchased by Optimum Diamonds LLC, the company that also bought the Argyle Everglow.

Optimum Diamonds' CEO David Shara commented in a news release, "Optimum Diamonds is delighted to have won the Argyle Everglow. This historic red diamond is one of the diamond world's rarest treasures and it is a privilege to be able to add it to Optimum's collection. The Argyle Liberte is a mesmerizing violet diamond that fits perfectly with Optimum's quest for the truly exceptional in the world of fancy colored diamonds."

Rio Tinto said that its entire 2017 tender, comprised of 58 pink, red and violet diamonds, earned a record result for the company, proving there is high demand for rare, fancy color diamonds.

Graff Diamonds won the tender's third lot, a 2.42-carat cushion-cut pink diamond called the "Argyle Avaline," the largest pink diamond Rio Tinto offered this year.

The Argyle Avaline was the largest pink diamond offered in Rio Tinto's tender in 2017. Graff Diamonds purchased the 2.42-carat stone.

Graff founder and Chairman Laurence Graff said: "We have always been passionate about pink diamonds; acquiring these incredible miracles of nature is a pleasure and an honor. We will take great care to respect the delicate beauty of Argyle Avaline as we craft a setting for this exquisite and exceptionally rare diamond."

GIA Reports Finding Lab-Grown Diamond with Fake Inscription

 Carlsbad, Calif.--In the latest issue of Gems & Gemology, the Gemological Institute of America reported finding a man-made diamond inscribed with a report number matching a mined diamond.

The article, authored by Christopher M. Breeding and Troy Ardon, states that the stone in question came through the lab's Carlsbad facility.

A client, whom the GIA did not identify in the article, submitted the diamond for an updated grading report because they "noticed inconsistencies" with the GIA report information, the article states.

The diamond was inscribed with the number of a GIA report issued in 2015. That report was for a natural, untreated diamond graded as 1.74 carats, round brilliant cut, D color, Excellent cut grade and VVS1 clarity.

But when graders looked at the stone, the article states they found it was a round brilliant with Excellent cut grade but 1.76 carats, with F color and VS1 clarity.

Moreover, the GIA's screening processes--which are done on every stone to determine if it is natural, treated, lab grown or a simulant--indicated that the diamond needed additional testing to determine its origin.

Examination with the DiamondView machine showed that the submitted stone was not a natural diamond but was grown using the high-pressure, high-temperature (HPHT) process.

The article also states that the FTIR (Fourier Transform Infrared) Spectra showed that the natural diamond from the original report--the one that matches the report number inscribed on the girdle of the man-made stone--was Type IA (about 95 percent of natural diamonds are this type) with aggregated nitrogen impurities, while the newly submitted diamond was Type IIb with boron impurities.

In addition, the GIA said upon closer examination, the font used for the number inscribed on the diamond's girdle was different from the one used by GIA.

When asked if the GIA was investigating the source and scope of this fraudulent inscription, the lab said: "While we are aware of reports of fraudulent inscriptions, we rarely encounter this type of blatant fraud."

The lab added that the stone was returned to the submitting client, which, it reiterated, was the one that noticed inconsistences with the GIA report information and sent in the diamond for an updated report.

In the article, the GIA advises members of the trade with any doubt about some aspect of a diamond to send it to a gem lab for verification.

〔即時新聞／綜合報導〕西非的獅子山共和國蘊藏豐富鑽石，繼今年3月挖到一顆709克拉重的超大鑽石原石後，又發現一顆高達476克拉的巨大鑽石，專家指出，這將成為世界上第29大的鑽石。

綜合媒體報導，獅子山國家礦業局總局長汪戴伊（Sahr Wonday）表示，在東部的科諾地區再度出土一顆巨鑽，這顆鑽石原石重達476克拉，汪戴伊說，這項最新發現標識著該地「礦藏含量豐富強而有力的證據」；今年3月同一個地區也挖出一顆709克拉重的超大鑽石原石。

這顆709克拉重的鑽石被命名為「和平鑽石」是該國史上第2大顆的鑽石原石，更是世界前20大的鑽石，為了洗刷過去「血鑽石」的污名，「和平鑽石」在5月於國內公開拍賣，但僅喊價到780萬美元（約2.34億台幣）而流標，預計12月初移師到紐約再度拍賣。

獅 子山是世界上最貧窮的國家之一，在1991年到2002年間爆發長達11年的內戰，造成12萬人死亡，數百萬人流離失所，當時叛軍的資金就是仰賴著非法鑽 石交易，而那些非法鑽石就被稱為「血鑽石」，其中協助叛軍奴役工人採鑽石，並走私販賣的商人迪賽狄爾（Michel Desaedeleer）於去年9月在比利時監獄中過世。

內戰結束後，獅子山致力於鑽石交易透明化，盼拍賣鑽石所獲之收益，用來改善國內基礎建設，包含飲用水、生活用電、教育、醫療衛生、道路交通等。

Trapiche gemstones are a great example of this. The geometry and symmetry of the stones created by their rayed patterns are truly spectacular and valued for both their beauty and uniqueness.

Trapiche emeralds were first on the scene, at least according to written records, with the name adopted because of their resemblance to "trapiche de caña de azucar," the Spanish name for the six-spoked cogwheel used in sugar mills.

Beyond the almost-immediate fascination trapiches spark with their beauty and rarity, there's plenty to know about these stones, starting with these five points below.

1. Trapiche gems have equivalent crystallographic growth patterns separated by boundaries of inclusions.
According to the Gemological Institute of America's "Gems & Gemology," these boundaries intersect at a central point or extend from a central core, creating a pattern that, often, resembles a wheel.

Trapiche gems also are characterized by their high symmetry--which appears in a hexagonal manner, for example, for emeralds--and feature inclusions of organic matter.

2. There are a number of gemstones that can be found in trapiche variations.
The spoke patterns that define trapiche gemstones are best known in the popular green beryl, but one can also find trapiche corundum, garnet, tourmaline and chiastolite, though chiastolite only exhibits four arms, InColor said.

3. The history of (finding and studying) trapiche is long.
Or at least for emeralds, that is.

According to Gems & Gemology, Colombian trapiche emeralds were first described by French mineralogist Emile Bertrand in 1879 at a meeting for the Société Géologique de France, though they did not yet have a name.

The first known use of trapiche emeralds in jewelry is in an early-19th century gold ring by an unknown artist that was bequeathed to the Victoria & Albert Museum in London.

Trapiche rubies from Burma, meanwhile, were first documented by the GIA in 1995, according to InColor, but the stones also have been found in Guinea, Kashmir, Pakistan, Nepal, Sierra Leone and Tajikistan.

Trapiche sapphires first appeared on the gem market in early 1996, when samples were offered in Basel by a Berlin gem dealer, and have been found in Australian, Cambodia, China, France, Kenya, Madagascar, Nepal, Sri Lanka, Tanzania and more.

 

 4. Supply and demand have stayed fairly consistent.
As with any rare gemstone, trapiches are still pretty hard to come by, goldsmith and jeweler Paul Farmer said.

But there may be an opportunity, however big, with pieces or partial trapiche stones, he said, which can make unique pieces such as butterfly wings.

He sees some opportunity in this area as more lower-quality gems come onto the market, noting that they can "make fun, inexpensive pieces," he said.

Jeffery Bergman of Primagem said emerald trapiche continue to be the most available and in highest demand of all trapiche gems.

Trapiche rubies from Burma, meanwhile, tend to be mostly under 1-carat in size, he added, and rather dark, requiring thin slicing to get the best color and trapiche pattern, which has had the effect of restricting their use in jewelry.

Bergman also said fine trapiche sapphires from Mogok, Burma are still in high demand with very limited supply.

"Most of the material on the market is semi-translucent to opaque, and the occasional gemmy translucent example fetches several thousand dollars per carat," he said.

He added that Vietnam has been producing some semi-translucent-to-opaque trapiche sapphires ranging in size from 5 to more than 50 carats and reasonably priced at about $50 per carat for finer pieces.

Simon Watt of gemstone dealer Mayer & Watt also said that supply hasn't changed much, with the fine stones still hard to come by and with the bulk of demand from gem connoisseurs.

What's more, "There's never enough (supply) for the demand to be so great," he said.

In fact, he hasn't seen a resupply of trapiche sapphires in the past year.

The difference for him, though, is that he's been marketing the material for years, and it's paid off with an increased buzz around the gemstones.

5. Prices have increased.
The downside to the buzz he's created, Watt said, has been a price increase; he said he's seen prices double in the past five years for fine material.

This is not to mention the rarity of the stones keeping prices high.

Bergman also noted that prices of emerald trapiche have doubled and tripled over the past several years as well-known jewelry designers like Selim Mouzannar, Omi Prive and Erica Courtney have incorporated them into award-winning designs.

Still, Watt is hopeful prices will start leveling out, if nothing else, and notes that when he does get trapiche stones, he has rarely has trouble selling them.

"The end user is really looking for something very unique that blows their mind. Trapiches do just this because you look at them and think, 'Nature is truly incredible, isn't it?'"
