Welcome to AIGS
In 1977, Jeff Wildman (USA) and AIGS Chairman Henry Ho (Thailand) invented the "Porta-Lab" which was the world’s first portable gemological laboratory. AIGS was the first laboratory in the world to purchase a Raman spectrophotometer for gemstone reports, thus setting a trend which would subsequently be followed by all other major international laboratories.
In 1988, AIGS founder W. K. Ho headed up a group consisting of Dr. Edward Gubelin, Alan Jobbins, Ken Scarrett and Dr. Adolf Peretti becoming the first foreign-based laboratory team to enter the Mogok gemstone tract since Burma’s military coup d etat in 1962. Alongside representatives from Switzerland’s Gubelin Laboratory (Dr. E. Gubelin) and Gemmological Association of Great Britain (A. Jobbins), AIGS became the first Asia-based laboratory to visit Vietnam’s Luc Yen ruby mines.
In 1993, AIGS became the first laboratory in Asia to participate in an exploratory trip to Sierra Leone’s diamond deposits. AIGS was chosen to be the first laboratory to certify the Queen Sirikit Diamond in 1992, as well as being given the same honor for the King Bhumipol Diamond six years later.
AIGS was the first laboratory to perform a comprehensive gemological report on the Golden Jubilee Diamond - then owned by a consortium led by AIGS President, Henry Ho - which, at 545 carats, remains the world’s largest faceted diamond.
AIGS was the first laboratory in Thailand to produce a comprehensive report on ruby glass-filling treatments.
AIGS invested in the DFI Mid-UV, a high performance device for detecting HPHT and CVD synthetic diamonds of any size, and is able to test up to 3,000 melee stones per hour.
AIGS developed Ruby, Sapphire and Emerald identification charts for laboratory and office use.
AIGS is one of the organizers of the World Ruby Forum, in cooperation with the Gem & Jewelry Institute of Thailand and Thailand's Department of International Trade Promotion, Ministry of Commerce.
