About Don Kogen
With over 20 years' experience in the gemstone and jewelry industry, Don Kogen's lifetime passion for gemstones started when he travelled to Thailand with his Father, only to be abandoned on the streets of Chanthaburi at the age of 13.
While still in his teens, Don familiarized himself with every aspect of the local gem industry found in Chanthaburi, Thailand - from mining and cutting, to trading in the weekend gem markets. While watching dealer's haggle and trade Don taught himself how to speak Thai and quickly picked up the vocabulary of making deals.
During Don's travels he was fortunate to gleam a huge amount of knowledge and some well-guarded secrets of the trade from seasoned gemstone traders, but it wasn't until the 80's that his professional career seriously took off.
Frustrated by the inefficiencies of traditional gem trading, where numerous middlemen can increase the price of a gem, often by figures in excess of 1000% from mine to market, Don believes in developing businesses that give consumers the opportunity to purchase direct from the primary source, enabling the most direct connection between individual miners and customers, creating additional value for both sides.
Internationally respected and admired, Don has a huge impact on the gemstone industry. As a professional member of the ICA (International Colored Gemstone Association), an organization whose members include the top gemstone miners, cutters and dealers throughout the world, he has represented Thailand at the GILC (Gemstone Industry Laboratory Conference) on several occasions and was formally the ambassador for the CGA (Chanthaburi Gem and Jewelry Traders Association). Apart from numerous trade press articles, Don has also appeared in the international media multiple times regarding his influence on new gemstone discoveries.
Don has dedicated himself to his passion for over 25 years, traveling through 100 countries across 6 continents - relishing in the thrill of tracking down gemstones from around the globe, no matter how deep or how remote the area is. Don has been working with the Gemguys® for over 15 years, slowing building and developing the team to what we see now. With its head office in Houston, Texas, Don regularly travels to and from all the Gemguys® bases.
Don's focus in life is to introduce the world to the rarest and most beautiful treasures that Mother Nature provides.
Coming from humble beginnings, Don has always been grateful to Chanthaburi and the gemstone industry for giving him his passion and purpose, and as such Don gives much back to the town he called home for so many of his youthful years, by financing Schools, local businesses and the town municipal needs.
Through all these adventures Don's four children remain his main motivation. He states, "I just want to give my children the opportunities I never had.

The network has greenlighted a series ..., 3 Feb 2014 [cached]
The network has greenlighted a series titled Game of Stones about an "extreme gem hunter" named Don Kogen, who is described as a "legend" in the business. Kogen, who is CEO of Gem Guys Inc., specializes in rare stones "from the most dangerous and lawless places on earth, racing the clock to be the first to each new find, always staying one step ahead of the competition."
The series, set to debut at 10 p.m. ET/PT on Friday, Feb. 28, will follow the adventures of Kogen as well as his crew. Each episode will find them in a new country, including Thailand, Turkey, India, Tanzania and Brazil, as they try to beat their competitors to be the first to find the rare stones. They also must deal with the constant risk of being robbed, carjacked and ambushed.
The series joins a successful lineup of shows that also includes Discovery's top-rated Gold Rush and Jungle Gold, which follow crews on the hunt for gold in dangerous and remote locations.
Read more about Kogen and his team below:
Kogen left school in Houston as a preteen to travel to Thailand with his father. As a teenager, he was left to his own devices in a sink-or-swim situation and began to sell stones on the streets of a Thai gem trading town to survive. Kogen sacrificed much along his path to success, chasing his dreams for bigger and rarer stones which kept this gem addict's blood pumping. Kogen later returned to the U.S. and last year traveled to 50 countries in search of the rarest stones on earth, including Cambodia 'Sunset' Rubies, Royal Blue Sapphires, Canary Yellow Tourmaline and Transvaal Emeralds.
Kogen cornered the market on rare stones by building a tight and trustworthy team that includes Australian-born Gavin, a gemologist who will do anything to get his adrenaline fix. Tony is the broker, the money man, who has an acute understanding of the ups and downs of the rare stone industry. Fear is ex-military and a former bomb disposal unit member whose many talents are crucial to each success - he also protects the team and their cash, up to one million dollars at a time.
The Network's new series featuring America's most extreme rare stone hunter Don Kogen chases new finds in the world's deadliest destinations.
