Gem Labs To Present Latest Innovations At June Hong Kong Jewellery & Gem Fair

Industry stakeholders who want to stay on top of the latest innovations, research studies and evolving technologies impacting gemmology should visit the Gemmological Laboratories Zone of the June Hong Kong Jewellery & Gem Fair.

Scheduled for June 20 to 23 at the Hong Kong Convention & Exhibition Centre (HKCEC), the June Fair will bring together the major names in the world of gemmology, including the Asian Gemmological Institute and Laboratory Ltd, DANAT (Bahrain Institute for Pearls & Gemstones), Gemological Institute of America (GIA), GRS Lab (Hong Kong) Ltd, Gübelin Gem Lab Ltd, Guild Gem Laboratories, ICA GemLab Ltd and Swiss Gemmological Institute SSEF.

“It’s imperative that we keep up with the latest advances in the gemmological field because these are indispensable to inspiring consumer trust and confidence in the gemstone and jewellery sector,” says Celine Lau, Director for Jewellery Fairs at Informa Markets.

DANAT – the Bahrain Institute for Pearls and Gemstones – will offer pearl and gemstone testing services at the show, noting that it will be the only lab to provide unique pearl testing services onsite. The lab will also have a display of natural Bahraini pearl jewellery pieces and historical pearling equipment, and a transparent lab section where show attendees may view and observe onsite testing. According to the lab, “DANAT stands out because of its commitment to excellence and unique reporting format.”     

GIA will give show attendees the opportunity to see live demonstrations of its newest instruments: The GIA iD100™ gem-testing device, the GIA UV Lamp and Viewing Cabinet, and the new GIA Polariscope.

The GIA iD100 gem-testing device combines advanced spectroscopic technology with GIA’s decades of diamond and gemstone identification research to separate all laboratory-grown (HPHT and CVD) diamonds and diamond simulants from natural diamonds. The desktop instrument can screen loose and mounted diamonds as small as .005 carat, with clear audio and visual results – “pass” for natural diamonds and “refer” for potential laboratory-grown diamonds and simulants that require further testing.

Those who require a device that could help evaluate fluorescence “consistently and accurately” might want to check out the GIA UV Lamp and Viewing Cabinet. This portable desktop device provides the same narrow band UV illumination used by GIA laboratories to evaluate fluorescence. The compact viewing enclosure includes a calibrated reference for the intensity of blue fluorescence in diamond, ranging from “None/Very Faint” to “Strong.”

The new GIA Polariscope tests the optical properties of gemstones to determine whether a stone is singly refractive, doubly refractive or is an aggregate. The updated device can further determine whether doubly refractive stones are uniaxial or biaxial. The Polariscope can also detect pleochroism in doubly refractive coloured stones.      

At the June Fair, SSEF will present GemTrack™, a service linking cut stones to the rough stones from which they originated using gemmological techniques. According to the lab, the service involves the combination of crystallographic, structural, chemical and microscopic analyses, which allow for a detailed and potentially unique characterisation and fingerprinting of a rough stone. These same features can later be identified during the investigation of a resultant cut stone, following the cutting and polishing process, and then documented on a GemTrack™ report.

“Given the growing demand for provenance and traceability in our industry, we felt that SSEF can provide a truly independent gemmological documentation for a gem on its journey from the rough to cut state, and even to its being set in jewellery,” says Dr. Michael S. Krzemnicki, director of SSEF.

A GemTrack™ document may also be issued if a gem is later mounted in jewellery, in order to document the stone all the way from rough state to an item of jewellery.

The report will not make any specific claims of mine of origin. However, when credible documentation is provided – such as transparent sales receipts from a rough auction – it may state that based on provided documentation, a gemstone was sourced from a specific company or auction, SSEF notes.

Led by company director Omar Wahid Hatta and chief gemmologist Dietmar Schwarz, ICA GemLab will offer its Premium Report at the show, with the express service charge waived. Same-day service for the Standard Report may also be availed of and issued by 6pm if the stones were received for testing before 11am. Mobile lab services will be available on a first-come, first-served basis.

ICA GemLab will also actively encourage gemstone industry stakeholders to take part in the ICA Congress in Bangkok, which is scheduled for October 12 to 15. The congress will focus on the theme, “Ruby: Eternal Love.”      

GRS Lab (Hong Kong) Ltd will launch its “Platinum Award Report Book,” which is presented only to the rarest gems it has tested. In addition to a detailed description of the gemstone and the results of the comprehensive tests done on the stone, the book will include historical and geological background information about the source of the gemstone.

The lab has implemented new AR (Augmented Reality) technologies, which allow a seamless combination of the handmade and fully customised book with modern video technologies. Printed images inside the book become animated, which allows one to observe the tested stones on a 360-degree rotating surface, in addition to videos about the mining of the stones at the source, according to GRS Lab.

Clients may submit and collect the stones to be tested directly at GRS Lab’s booth at the HKCEC.  

Acknowledged as the oldest gemmological laboratory in Hong Kong, the Asian Gemmological Institute and Laboratory Ltd (AGIL) will provide onsite gemstone testing and identification services, and present its latest diamond-screening instruments at the June Fair. It will also highlight its newly designed Professional Jewellery Grading Lamp and ABCD+S testing set, and its AGIL Special Professional Gems and Jewellery Courses.

Some of the advanced instruments currently being used by the lab are the Gemray 5000-EDXRF Spectrometer, PL-Image Spectrometer, Natural Diamond Detector and Toptek Dual Source Raman Spectrometer.
