Dear all,
some interesting research pdfs can also be found on the "News from the research" page of www.gia.edu Besides the pdf already available on the Bangkok website, you will also find pdf from GIA researcher working in New York and Carlsbad.
The most recent pdf is a very interesting study about a treated red diamond:
"Treated Fancy Red Diamond" by Paul Johnson and Christopher M. Breeding:
The other recent pdf is a great study by John Koivula:
"Micro-Magma Chambers in Natural Rubies and Sapphires: The Behavior of Some Mineral Inclusions in Corundum At High Temperatures":
The views expressed here are V. Pardieu’s opinions and do not necessarily reflect those of GIA Laboratory Bangkok (http://www.giathai.net)where he is an employee since Dec 2008.
