Once again, the AGTA GTC will be participating in The JCK Show – Las Vegas 2006, offering a range of gemological services, such as:

  • Identification reports for all kinds of gemstones, including the identification of clarity enhancement fillers.
  • Country-of-Origin reports for ruby, sapphire and emerald.

    The AGTA Pavilion has special dates and times, opening and closing one day before the main JCK show. The AGTA GTC Mobile Laboratory, located in the AGTA GemFair Cultured Pearl & Jewelry Pavilion, is open Friday, June 2nd to Tuesday, June 6th. Hours are 10:00 AM to 6:00 PM on June 2nd and 9:00 AM to 6:00 PM from June 3rd–6th. The AGTA GTC Mobile Laboratory is planning to deliver the reports to clients within 1–2 days and services will be available during normal show hours.
     But even better than submitting gemstones during the show is to submit them to the AGTA GTC prior to the show, where you can enjoy our normal rates (gems tested at the show will incur a slight surcharge). By doing so, you'll have the gemstones in your showcase ready for sale with reports. Gemstones submitted by Tuesday, May 23rd, will be returned to you at the show. Hurry up and have your gemstones tested today!

Colombian Gem News
Moderator: Stuart Robertson (Gemworld International)
Panelists: Loretta Castoro; Dr. Lore Kiefert (AGTA GTC); Ron Ringsrud (Ronald Ringsrud Co.); Robert Weldon (GIA)
Thursday, June 1, 2006
10:30–11:30 AM

Recently, this group of panelists closely witnessed mining and treatments of Colombian gemstones. What they discovered was a new generation of Colombian mine owners who have formed strategic alliances aimed at benefiting the region as a whole. Through cooperation, this group hopes to add value and restore confidence in the Colombian emerald market by implementing Fair Trade principles and product certification with meaningful disclosure. The Colombian market is actively pursuing international buyers by establishing an emerald center near the airport in addition to the major trading center in Bogota's business district. Hear from a reporter, a value-added specialist who is a former colored gemstone buyer for Tiffany, the head of the AGTA GTC, and a dealer specializing in Colombian gemstones in this session.

She will also deliver a lab update:
