GIA iD100™

GIA has introduced an easy-to-operate, sophisticated desktop diamond testing device to reliably identify mounted and unmounted natural diamonds. You can see the device in action at both venues during the show. The iD100 may be reserved at the list price of $4,995 USD at the booth.

The GIA iD100 combines the advanced spectroscopic technology with GIA’s 60 years of diamond and gemstone identification research to distinguish natural diamonds from synthetic (HPHT and CVD) diamonds and diamond simulants. It is the latest in a series of instruments and services from GIA that addresses concerns in the trade about the possibility of undisclosed synthetic or treated diamonds in the supply chain.


GIA M2M™ is a new digital storytelling platform: an innovative way to combine scientific information with engaging content to involve your customers in the fascinating story of their diamond. Ensure they know the facts they need to make an informed purchase, while connecting on a deeper level with the romantic journey of their diamond. GIA representatives will share more about M2M and how you may be able to get involved.

Melee Analysis Service

The GIA Melee Analysis Service separates natural, untreated diamonds from simulants and potentially synthetic or treated diamonds, and sorts the screened diamonds by color range. See a video at the booth and find out more.

In addition, ask about diamond grading and colored stone analysis using the convenience of You’ll also discover more about special savings on the GIA DLScope and other GIA instruments.


Attend GIA GemFest Hong Kong during the fair. These presentations are timely and relevant to new developments and issues in the gem & jewelry marketplace.

Synthetic Diamonds & Their Identification – Current Status

Thursday, 14 September
Room 201B
11 a.m. to 12 p.m. Seminar

Wuyi Wang
Vice President, Research and Development, GIA

Significant numbers of synthetic diamonds – from melee to gem-quality diamonds over 10 carats – are being produced for the jewelry industry. It is critical to understand how to effectively and accurately separate these from natural diamonds. In this presentation, GIA will report on the developments in synthetic diamonds and their identification. The presentation will include GIA’s fully automated Melee Analysis Service and a demonstration of the GIA iD100 instrument to identify natural diamonds in jewelry pieces.

Large Diamonds Examined at GIA

Saturday, 16 September
Hong Kong Convention & Exhibition Centre
Room S421
8:30 a.m. Continental Breakfast
9 to 10:30 a.m. Presentation

Tom Moses
Executive Vice President and Chief Laboratory Research Officer, GIA

The Constellation, an 812 carat rough diamond, was discovered in November 2015 at Karowe along with several other similar pieces of rough. GIA studied diamonds from this group using gemological and spectroscopic techniques to determine if perhaps they originated from a single large crystal. GIA Executive Vice President and Chief Laboratory and Research Officer Tom Moses will discuss the examination of three pieces, and the implications of the findings for our understanding of diamond formation.
