JGGL was founded in 1995 by Masashi Furuya who
had extensive experience in both gem testing and
trading. He and his family lived in Idar-Oberstein,
Germany in the 1960s where he was immersed in new
findings of gemstones, expert cutting and carving
techniques, as well as the development of analytical
methods in gem identification. His passion for gemstones led him to the sapphire rush in Ilakaka,
Madagascar in 1999 as a geological advisor. The
philosophy of Furuya and JGGL has always been that
gemstones are more than just a commodity; there is
an emotional aspect attached to them because they
carry the special attachment of miners, cutters,
dealers and customers. With this philosophy, Furuya
set up his laboratory to share his knowledge and
passion for gemstones with consumers, dealers, miners and all people related to gemstones.
Journal "Gem Information" & enlightenment for gemstones
From its establishment, JGGL focused on research and
sharing knowledge related to gemstones, such as in
contributions to The Japanese Journal of "Gem
Information" and special editions for gemstones, such
as on Paraiba tourmaline in "World of
Gemstones" that were highly appreciated in
Japan.
At the same time, Furuya gave many lectures to
gemstone dealers and end-users. He held a
seminar at the Institute of Gemology and
Jewelry Art Yamanashi Prefectural Government
for gemstones and appeared on television in
Japan to explain the theoretical formation of
gemstones. These activities have been
continued by his son, Masaki Furuya, after
Masashi passed away in 2007.
Furuya Collections
More than 15,000 gemstones and 2,000
minerals are in the collections of JGGL founder,
Masashi Furuya, who spent over 40 years collecting
them from all over the world. The specimens were
collected directly from the gem mines where he had
strong relationships with worldwide gem dealers. It
goes without saying that the wide variety of localities
of the sample stones helps with gem identification
and origin determination. The older stones, without
recent treatment, are quite helpful for the identification of new treatments using newly
developed equipment such as EDXEF (elemental
analyzer) and many kinds of spectrometers, including
microscopic Raman spectroscopy. These important
gem collections serve as the "brain" of JGGL.
Analytical Instruments
JGGL uses all necessary advanced analytical instruments. Specially, most of them are modified for testing gemstones with original attachments, and also for high throughput to test many samples quickly for routine gem testing. JGGL enjoys collaborations with manufacturers of analytical instruments, such as fluorescence and phosphorescence imaging for screening melee-sized synthetic diamonds and the Raman spectrometer for quick gem identification.

Founder: Masashi Furuya, D.Gem.G., F.G.A., C.G.J.
Japanese delegate of I.G.C., Assistant professor of
Institute of Gemmology and Jewelry Art Yamanashi
Prefectural Government. Spent more than 30 years in
the gemstone industry in Idar-Oberstein and Kofu city
and was the first to introduce agate cameo to
Japanese market. Co-directed sapphire mining in
Ilakaka, Madagascar from 1999 to 2002. Founded his
gem laboratory with his enthusiasm for gemstones in
the trend of decreasing natural beautiful gemstone
and the increase of new treatments for gemstones.
Passed away in October 2007.
