ABOUT OUR SEMINARS

This highly acclaimed seminar-workshop is conducted in selected locations around the world by the veteran and authority on gem treatments Ted Themelis based on his 30 years experience in actually treating gems. The most updated information and samples are presented and gems are examined by the participants. More than 350 gemologists have attended this semimar since August 2010. The seminars provide a quick, update, and in-depth, discussion into the current gem treatments as practiced in Ted's thermo-chemical Gemlab in Bangkok, Thailand. The seminars blend concepts of thermo-chemistry and gemology interacting with actual specimens provided for examination to attendees; past erroneous gemological concepts are brought into light and misleading information on the country-of-origin reports are discussed. Documentary videos on gem treatments as performed in Sri Lanka, India, Thailand, Vietnam, USA and Thailand will be shown. Lastly, attendees have the opportunity to examine rubies, sapphires, spinels, spessartites heated by Ted's new proprietary methods and techniques.

Objectives of the seminar:

  • to promote true understanding of the gem treatments
  • to provide education and learning experience in treating gems
  • to address complex technical issues in treating gems
