Disclosure of Colombian Emerald Nondisclosure

In an online feature story for the New York based business and financial news Bloomberg.com, Colombia-based reporter Helen Murphy points fingers at nondisclosure of emerald enhancements in “Colombia’s Emerald Tricksters Tarnish Image for High-Grade Gems.”

Pointing out the well-known emerald enhancement tradition, Murphy notes a lack of enhancement information given by Colombian emerald suppliers. “Stones from the Boyaca mountains where Lozano works helped Colombia build its reputation as the source of some of the world’s finest emeralds.

The industry and the government are planning to bring greater transparency to the market and certify gems.”
