Technology and technicians are an important part of EGL USA's
capabilities. Our gemologists are highly educated and experienced
EGL USA's gemological team includes professionals from many
different fields, including geology, mineralogy, chemical
engineering, education, and mining. Few laboratories
can boast of such a diverse mix of talent; it's just another
important EGL USA difference.
In 2003 the JCK
Jewelry Industry Fund awarded EGL USA a significant research
grant for its ongoing work in the identification of natural
and synthetic diamonds modified by high pressure high temperature
Tools of Gem Identification:
Gem technology has advanced significantly over the last few
years. The jewelry industry is now faced with an array of
new gemstone enhancements and treatments, some of which are
identifiable only with advanced gemological equipment.
EGL USA continues to meet the challenges of gem identification
by maintaining a truly state-of-the-art gem laboratory. Some
of the tools in our laboratories include:
- Zoom binocular microscopes
and other basic gem-identification instruments such as refractometers,
polariscopes, and spectroscopes.
- Dimension machines for diamond
- A MacBeth color analysis machine
and numerous lighting units for the grading of diamonds.
- The most advanced and safest
laser-inscription machine available.
- An FTIR Infrared Spectrometer
- Spectrophotometers (important
for the detection of treated gemstones)
- Digital Pearl X-ray. EGL is
one of only three labs in the U.S. that offers X-ray analysis
