On October 13-14, 2012, more than 160 industry colleagues from eight countries collaborated at the third World of Gems Conference. Eleven speakers presented over the two days and attendees learned, networked and enjoyed the social events planned during this high energy weekend. This niche conference combines gemological information, a little history, a little science, and of course pricing as only Gemworld can provide.
About our attendees:
- 72% were GemGuide subscribers
- The average subscriber has used the GemGuide for 9 years
- Almost 1,400 combined years of GemGuide usage.
