beryl, synthetic beryl, emerald, gems

Recently submitted to both the Los Angeles and New York offices of GIA'S Gem Trade Laboratory, Inc., were several faceted examples of a sophisticated type of synthetic emerald. The stones resemble in many ways synthetic emeralds of Russian hydrothermal manufacture that were recently obtained by Mr. Thomas Chatham in Hong Kong (see figure 2) and generously provided by Mr. Chatham to the Los Angeles lab for research.
