Las Vegas--Two men working in tandem stole a 20-carat diamond from an exhibitor's booth in Las Vegas, the Jewelers Security Alliance said in an alert issued Thursday afternoon.
It is the biggest jewelry theft at a trade show so far this year, and one of the largest in recent years.
The incident began just before 3 p.m. on Saturday, June 2 at the booth of an "international diamond exhibitor" at one of the jewelry trade shows. (The JSA does not disclose the victim's name or the name of the trade show in cases such as this.)
The two suspects, pictured below, approached the booth and were able to reach over the showcase and slide it open while employees weren't looking because it was not locked.

They then placed a catalog on the showcase—placing objects on showcases is a technique commonly deployed in distraction thefts—and reached in again but did not remove any items.
About 10 minutes later, the pair came back and entered the booth. While one suspect chatted with the exhibitor at a table, the second man moved to the corner of the booth and took a 20-carat diamond from the open showcase.
JSA President John J. Kennedy said Thursday that he does not have a grading report from the diamond, so neither a price estimate nor additional details about the stone are available at this time.
He added that this is the largest jewelry theft at a trade show so far this year and one of the largest he knows of in recent years.
The JSA reminds exhibitors not to leave showcases unlocked at jewelry trade shows, expect when actually taking out merchandise or putting it back in.
They also need to have enough personnel at their booths so they can keep an eye on everyone at all times.

GIA's iD100 gem testing device
The Gemological Institute of America (GIA) is conducting a synthetic diamond seminar scheduled for June 19 in Hong Kong. The one-day programme, taught by GIA research scientists and experienced classroom instructors, will combine lectures with practical lab instruction, including the latest GIA instrumentation for differentiating natural diamonds from CVD and HPHT synthetic diamonds and diamond simulants.
"GIA examined and characterised the earliest gem-quality synthetic diamonds nearly 50 years ago. Since then, we have continued to build the Institute's expertise in identifying synthetics through robust, published research into their properties. This combination of decades of experience in delivering quality, relevant education and in-depth independent research into natural and synthetic diamonds is unique to GIA," said Dr. Wuyi Wang, vice president of research and development. "As the public becomes more aware of gem-quality synthetic diamonds – including melee sizes – it is imperative that the industry is prepared with training and expertise to address consumer concerns."
GIA senior research scientist Dr. Ulrika D'Haenens-Johansson will present the seminar along with bilingual GIA education staff. The seminar will be offered at other GIA locations later in the year.
Seminar participants will gain in-depth knowledge of advanced diamond identification techniques and will have hands-on experience with current production synthetic diamonds and the latest detection technology, GIA said.

Emerald has been the quintessential standard for all things lush, rich and green for centuries. There are many reasons why emeralds were one of the four gemstones originally deemed "precious."
We now know that all gemstones are precious, yet emeralds continue to be a symbol of wealth and abundance.
Those lucky enough to be born in May boast emerald as their birthstone, and the rest of us buy them anyway. Emeralds continually captivate jewelry designers, and today it feels like we have more stunning emerald jewelry than ever before.
Here are a few Amanda's Style File selections in every price range.

A wide array of coloured gemstones and fancy colour diamonds are expected to command attention at Bonhams' upcoming Rare Jewels and Jadeite sale in Hong Kong on May 27.
Headlining the lots is a 4.01-carat Pigeon's Blood Burmese ruby and diamond ring, which is valued at HK$3.5 million to HK$5 million or around US$445,000 to US$635,000. The ring is accompanied by reports from leading gemmological laboratories.
Another highlight of the sale is an 8.56-carat no-oil Colombian emerald and diamond ring with a pre-sale estimate of HK$5 million to HK$6 million or around US$635,000 to US$765,000.
Bonhams Asia Director of Jewelry Graeme Thompson commented, "The market has experienced the biggest price increases for emeralds and rubies which respectively have seen a 1,900 percent price increase for emeralds and a 1,100 percent increase for rubies in the past 10 years."
The sale will also feature a 12.92-carat Kashmir sapphire, which was recently discovered in a bank vault. The ring is estimated to fetch between HK$950,000 and HK$4 million or about US$120,000 to US$510,000.
"Kashmir sapphires are the rarest of gemstones and collectors are prepared to pay princely sums for top-quality specimens. Sapphires have experienced a 970 percent price increase over the past decade," noted Thompson.
A collection of rare fancy colour diamonds, including a 10.03-carat oval-cut fancy brown-pink diamond valued at HK$3.1 million to HK$5 million (around US$395,000 to US$636,000), will also be auctioned off.

This jadeite bangle was the highlight piece of the Sotheby's Hong Kong Magnificent Jewels and Jadeite auction, but failed to find a buyer on Tuesday.
The rare bangle was expected to sell for $10.2 to $12.8 million at the Magnificent Jewels and Jadeite sale on Tuesday but failed to reach the reserve price.
The auction house described the piece as having a full, emerald-green color with "fine texture." It was named as such for its circular form and for the ancient Chinese belief that jade is the "stone of heaven."
When contacted by National Jeweler for comment, a Sotheby's spokesperson said that while the jewelry and diamond markets continue to "enjoy solid support" across price tiers, the jadeite market remains price sensitive.
Some of the other notable lots sitting at the top of the pre-auction estimates didn't sell, including an unmounted D color, flawless brilliant-cut diamond weighing 17.63 carats, expected to sell for up to $2.8 million; a signed Monture Cartier ring featuring a 14.72-carat step-cut Colombian emerald and brilliant-cut diamonds that Sotheby's thought could sell for up to $1.4 million; and a ring with a 14.18-carat step-cut fancy blue diamond with pink-tinted brilliant-cut diamonds, expected to go for between $5.9 and $7.6 million.
The top lot of the sale turned out to be a ring, pictured below, featuring a cushion-shaped Burmese ruby weighing 24.70 carats, set within a surround of pear-shaped diamonds. The shank is pavé-set with brilliant-cut diamonds with a pink tint.
It garnered $11 million, falling within its pre-sale range estimate.
Falling at No. 2 was a pair of earrings featuring pear-shaped diamonds weighing 13.01 and 12.97 carats hanging from surmounts with 1.03- and 1.01-carat diamonds. They sold for $3 million.
There also was a 30.16-carat cut-cornered rectangular step-cut fancy vivid yellow diamond ring that went for $2.8 million and a 5.01-carat cushion-shaped fancy vivid purplish pink diamond with shield-shaped diamond shoulders that sold for $2.5 million.
A ring with a square emerald-cut fancy vivid orangey-yellow diamond weighing 10.30 carats set between two tapered baguette diamonds garnered $1.4 million.
Tuesday's Magnificent Jewels and Jadeite auction sales totaled $48.6 million. For all results, visit Sothebys.com.
