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.

The AGTA Gemological Testing Center encounters unusual gemstones in the midst of more routine submissions. Sometimes these unusual gemstones are set to drain consumer confidence and, consequently, the dealer or retailer's profitability. Learn what AGTA is watching for in the Center now and how GTC works on identification, treatments, and country of origin.
