In the past 30 years, we have gained a valuable experience in the international gem industry. As a result, vast amounts of firsthand and and verifiable data have been accumulated from multiple sources, each serving a specific purpose; thus, over the years we have built an enormous data base, image bank, and reference specimens collection from many gem deposits situated in Colombia, Myanmar (Burma), Tanzania, Thailand, Sri-Lanka and elsewhere. In our archives include various cultural and ethnological features connected with the daily life in the globalize gem industry especially in Southeast Asia.
