MEMORABLE MOMENTS

OUR BEGINNING

Waing Kong Ho began his career in the gem trade in Burma. However, in 1964 when the country was being nationalized, he moved his family to Thailand with only $30 in his pocket. Ho's honesty and modesty was appreciated by buyers and sellers alike, and his name soon became well known throughout the international gem and jewelry community.

Ho was one of the true pioneers of the Thai gemstone industry and is recognized for bringing modernity and growth to a country that was fast becoming the "Gemstone Capital of the World." His vision brought forth the founding of AIGS nearly 40 years ago. Waing Kong Ho is also credited for building Asia's largest gems and jewelry marketplace, the Jewelry Trade Center(JTC).

Ho's success is attributed to his sacrifices, dedication and a relentless commitment to sharing his knowledge to help others. Waing Kong Ho's spirit lives in our hearts as we express our sincere gratitude for all that he accomplished during his life.
