ISG releases a new newsletter with smoking gun proof of the treating of blue tourmaline. They are calling this treatment “dyefusion”.

Thomas Hainschwang with Gemlab Gemological Laboratory announced that he recently examined and tested three(3) Emeralds that were purchased in India. The stones were reportedly guaranteed by the Seller to be completely natural and untreated Emeralds. The stones were translucent, green in color as one would expect, and full of fibrous inclusions. When examined under a microscope Hainschwang reported that these stones were not full of fibrous inclusions but, instead, actually had a fibrous structure! It was also noted that the green coloring was concentrated within this fibrous structure. This of course indicates that the material is dyed and not an Emerald.

Now, I am sure by now all of you are thinking something along the line of, ‘What the heck does monitor calibration, internet browsers, and color profiles have to do with gemstones and for that matter what are they!!??”. Am I close? LOL. Well, that is the goal of this article, as well as to give you the consumer and you the Retailer the proper tools and know how in order to make the purchasing of colored gemstones on the internet even more like shopping in a Brick & Mortar Storefront!
