Christopher P. Smith, G.G., President: American Gemological Laboratories (AGL)
 Chris Smith
is a 25 year veteran of the gem and jewelry industry with a distinguished international career. He began his interest in
gemology in 1986, when he joined the GIA Laboratory, then in Los Angeles, CA, after graduating from their graduate
gemologist and graduate jeweler's programs. Although initially a diamond grader, he quickly transitioned into the
Gem Identification department where he worked with such notable gemologists as Shane McClure, Robert E. Kane, Chuck
Fryer, Emmanuel Fritsch, and many others.
In 1991, Chris went to work for the Gübelin Laboratory of Luzern, Switzerland, where he eventually became Director
of the Laboratory. At that time, he was the first gemologist ever to have worked for both the GIA and Gübelin
laboratories. In his nearly 12 years at the Gübelin Laboratory, Chris oversaw operations, developed key new
services, and expanded the scope of Gübelin's operations globally.
He also pioneered research into several areas of gemology, including
the further development and refinement of country-of-origin criteria
for rubies, sapphires, emeralds, alexandrites, and other gemstones.
This innovative work included the characterization of ruby and sapphire
from a number of newly discovered deposits, such as rubies and sapphires
from Mong Hsu, Nepal, Tajikistan, and Vietnam, as well as other localities.
As part of his research activities, he has visited a number of gem mines,
including those in Myanmar, Sri Lanka, the Ural Mountains in Russia, Australia,
Tanzania and Thailand. While focusing a great deal of his efforts on the
determinations for country-of-origin, he also has worked extensively on the
distinction between treated and non-treated gems, including research on a
variety of heating techniques for corundum, HPHT treatment of diamonds, and
other treatments. The origin-of-color and its identification in ruby,
sapphire, diamond, coral, tanzanite and other materials, the identification
of and distinction between natural and synthetic gems, and the further
development of analytical techniques and their applications in gemology
also have been focuses of his work.
In 2003, Chris returned to the GIA Laboratory, this time in New York.
As the Director of Identification Services, he was involved with the
development of colored gemstone services and research. In December of 2006,
Chris joined the American Gemological Laboratories (AGL) as Vice President
and Chief Gemologist to spear-head the growth and development of their
colored gemstone services. In April of 2009, Chris became President and
owner of AGL.
Chris has made innovations to several areas of gemological testing and
its applications for the gemstone industry, including: landmark studies on
the detection of HPHT treatment of type II diamonds; methods for examining
the internal growth structures of gemstones; the application of infrared
spectroscopy for the distinction between non-heated and heated rubies and
sapphires; the 'TE' system of classifying and quantifying
the heat treatment and presence of heating residues in rubies and sapphires;
the development of 'off-site' gemological testing for major
laboratories; and most recently, a revolutionary classification system for
gem-quality rubies and sapphires.
Along with his identification and research work, Chris has published
and lectured extensively on various gemological topics. In 2010 he was
awarded an honorary Fellowship (FGA) by the Gemmological Association of
Great Britain (Gem-A) for his career-long commitment to the advancement
of gemology. In 2009 Chris received the Antonio C. Bonnano award for
Excellence in Gemology from the Accredited Gemologists Association (AGA).
In 2007, Chris was awarded the Richard T. Liddicoat award by the American
Gem Society (AGS). He is a past recipient of the Most Valuable Article Award
in Gems & Gemology and has been a member of their technical review board
since 1993. He also was a founding member of the Laboratory Manual
Harmonization Committee (LMHC).
ELIZABETH QUINN DARENIUS, B.Sc., G.G., FGA, Senior Gemologist
 Elizabeth ('Betsy') Quinn Darenius received her degree in
Geosciences from the University of Arizona, Tucson in 1993. While
attending the University, Betsy realized her passion for mineralogy,
gemstones and jewelry. In 1996, she enrolled in the Graduate
Gemologist resident program at GIA in Santa Monica. After earning
her G.G., she joined the staff of European Gemological Laboratory (EGL)
, Professional Gem Sciences in Los Angeles working for Tom and
Myriam Tashey as a staff gemologist. Betsy gained immeasurable
experience in diamond grading, colored gemstone identification,
publication, industry networking, and photomicrography by working
closely with the Tasheys, Gary Roskin, and Richard Hughes. Three and
a half years into her employment at EGL/PGS, she was promoted to the
position of Colored Gemstone Division Manager.
In 2001, she joined the West Coast Identification Department of
GIA where she had the opportunity to work with Shane McClure, John
Koivula and Dino DeGhionno. There, she spent four years performing
identification of colored gemstones and identification and
origin-of-color of colored diamonds in addition to authoring and
co-authoring several Gem News International and Lab Note entries for
Gems & Gemology [link to publications: Elizabeth Quinn]. While at
GIA, Betsy completed the FGA (Fellow of the Gemmological Association
of Great Britain) diploma course and passed her examinations the
first time through.
Betsy was chosen by GIA to relocate to Geneva, Switzerland in
2005 to work with Franck Notari and Thomas Hainschwang as a liaison
between the GIA Gem Tech Lab and the U.S. based laboratories. In
early 2007, she relocated to New York City and acquired the position
of Senior Gemologist at AGL.
Betsy has been a member of the Women's Jewelry Association for
thirteen years and was on the board of the Los Angeles Chapter for
just under five years, positions held include publicity chair,
secretary and vice-president.
