Fifth Edition of the Antwerp Diamond Trade Fair - January 26 to 28, 2014

For three days in January, ADTF takes over the diamond district
The fifth edition of the Antwerp Diamond Trade Fair (ADTF) will be held from January 26 to 28, 2014. For three days, the Antwerp diamond district's main thoroughfare, the Hoveniersstraat, will be red carpeted. The three trading halls of the Antwerp Diamond Bourse, the Diamond Club of Antwerp and the world's only rough diamond bourse, the Antwerp Diamond Kring, will be converted into three fashionable exhibition halls housing 80 of Antwerp's finest diamond firms as exhibitors. Exclusive, diamond-buying jewellery retailers and manufacturers are scheduled to visit from Europe, Russia, the Middle East, Hong Kong and China, the USA and South America.

Jacky Korn, a member of the ADTF Organizing Committee said the decision to add the Kring's impressive trading hall to the ADTF's exhibition venues enabled the number of exhibitors to grow to 80. "With 80 booked exhibitors and a waiting list of companies, we needed more space and the Kring provided the logical solution. We are currently in the process of redesigning the floor plans in order to improve the flow of traffic and enhance both the exhibitors' and buyers' experience". "This will be the largest and most exciting ADTF ever held," Korn added.

Committee member Nele Bouchier, who is Senior Manager of Public Relations and Communications of the Antwerp World Diamond Centre (AWDC) said that with the expansion of the fair to the Kring, the entire diamond district would fall under the spell of the ADTF," Bouchier noted. "Visiting buyers will be fully exposed to the character and charm of the district and understand even better what a unique opportunity they are given by being invited to this annual prestigious event," she stated.

The ADTF's buyers' registration will take place on the ground floor of the Kring building at Hoveniersstraat 2, with the exhibition halls located at both ends of the street.

The Antwerp Diamond Trade Fair is powered by the AWDC.

#Call4Entry - Ganoksin's Fourth Annual International Online Jewelry Exhibition

Ganoksin is pleased to announce its 
Fourth Annual International Online Jewelry Exhibition.

This year's theme will be 
"Changing Hues: Color Embraced by Metalsmiths Around the World."

The exhibition is open to all metalsmiths, professional and amateur, 
advanced and beginner, around the world.

(Image: Testing Japanese Patina Solutions from the book  Japanese Patinas)
The exhibition is seeking works whose primary theme is color, whether that be using colored materials, exploring creating colored surfaces, or encasing the object in color. Works should be about COLOR - not color as an accent or focal point, but with color embraced as their primary visual focus. Works where color is not the primary visual element will be rejected.

As this is an online exhibition the work will only be seen via the photographs metalsmiths submit. It is therefore vital that these be in focus, on a neutral background (preferably not textured), and do an excellent job allowing the viewer to really see the piece and the workmanship involved. 

Any photographs not meeting exhibition standards will not be used, and the submitting metalsmith will be asked to re-submit the entry with a higher quality of photograph. Works will be juried by the curator and director.

Fall 2013 Gems & Gemology looks at the Cheapside Hoard

Gems & Gemology Offers Behind-the-Scenes Look 
at the Cheapside Hoard Jewelry Collection

Fall 2013 issue reviews latest gemological research

The Fall 2013 issue of Gems & Gemology is 
now available.

The Fall 2013 issue of GIA’s (Gemological Institute of America) industry-leading peer-reviewed quarterly journal Gems & Gemology (G&G) journeys to the Museum of London’s astonishing new Cheapside Hoard exhibit of centuries-old jewelry; discusses “digits,” a naturally occurring pattern resembling fingers that is most often found in Ethiopian opal; unveils a useful clue indicating corundum heat treatment; reports on agates from Morocco; and much more. The issue is now available in print, and online with exclusive video content.

G&G’s cover story offers a remarkable preview of the Cheapside Hoard, an unrivaled collection of nearly 500 gems and jewelry pieces believed to have been buried in the seventeenth century that lay undisturbed in London until 1912.  Museum of London Director Sharon Ament and Senior Curator Hazel Forsyth discuss the remarkable history and gemological significance of the collection, which is being exhibited for the first time since the Hoard’s discovery.

Among the pieces chronicled are a gold locket featuring an image of Elizabeth I, a delicately carved cameo inspired by the Aesop fable “The Dog and His Reflection,” and an enameled gold ring set with a table-cut diamond, an evolutionary cut developed in the mid-fifteenth century. The exhibit is now on display through April 27, 2014.

Next is an examination of finger-like digit patterns mostly found in gem-quality Ethiopian opal. In another feature article, John Koivula, GIA’s chief research gemologist, documents a useful visual clue that indicates possible heat treatment of corundum, resulting from the conversion of limonitic residues to hematite in surface-reaching inclusions. The issue also includes a report on the chemical and mineralogical analysis of solid inclusions in Moroccan agate.

The Fall 2013 issue introduces a new G&G article category, the field report, which chronicles GIA expeditions to gem-producing areas and details future lines of research and publication. This issue recounts the July 2013 journey of Duncan Pay, G&G’s editor-in-chief, and a GIA research team to three sources of Oregon sunstone.

Since the first issue of Gems & Gemology was published in 1934, it has been recognized as one of the leading academic journals in its field. In 2013, G&G was made available in its entirety online. Today, the award-winning quarterly journal is available both as a print subscription and at no cost on GIA’s website. 

Additional details about G&G, full articles, more in-depth coverage, hundreds of additional photos, and exclusive video footage are available on GIA’s website at
