Gerard Quintin from the South American Gem Academy contacted All That Glitters about an upcoming article in Gemmology Today, as
he required photographs of fine examples of Ametrine. Geoffrey Dominy, whom we met and have been in contact with for about 30 years,
then reached out for more photos and info for this article. The article would be published by The World Gem Foundation,
of which Geoffry is the founder. Geoff is also the author of books on Gemology. The resulting article is:
The Legend of Bolvianite (Ametrine)
We have had the good fortune for more of our gemstones to be written up in Gems & Gemology Magazine, published by GIA.
(Our first publication in that magazine was back in the early 90s!) We brought a new find of unique quartz to the attention of GIA,
and these were intensively studied within their lab. The photos and technical information appear in the Summer 2018 Edition of Gems & Gemology:

GIA studys All That Glitters Unusual Cat's Eye Yellow Beryl.
To quote GIA regarding these Unique Gems - "...conducted the analysis and observed some very interesting and unusual inclusions in these heliodor samples...they all have very rare well-formed blue octahedral gahnite crystals (ZnAl2O4, spinel group mineral). The gahnite inclusions have never been reported before in beryl and maybe can be used as a diagnostic inclusion of the geographic origin of the stone after some more detailed research in the future."

Rapaport Article: New Discovery Same Name?
"On occasion, gem enthusiasts come across unusual specimens. It almost always occurs unexpectedly, while browsing the trade show floors or during a chance visit to a gem dealer's office. Sometimes they are presented as new minerals, trying to earn the public recognition. However, from time to time, we see something else - a familiar gem with an unfamiliar property or appearance. These are the one-of-a-kind pieces or collectors' items. Such were the gem specimens we found in L. Allen Brown's bag at the last Tucson show. He is the owner of All That Glitters in Methuen, Massachusetts."

The owner of All That Glitters, Mr. Brown, was recently contacted
by an individual who has a blog related to gemstones, and asked
whether he would be interested in writing an article for the blog.
The topic eventually decided on: 8 Tips on Purchasing Fine Gemstones Online
A website dealing in color within gemstones contacted Mr. Brown
about the interesting Bicolor "Demantoid" Garnet that GIA recently
had certed. An article on this gemstone now appears on the the
GemeWizard Website on the following page:
< Multi-colored andradite, or possibly Demantoid? >
If one calls it a Bicolor Demantoid, there is more of a likelihood that one would understand what this gem entails; whereas if called a Bicolor or Mulicolored Andradite, most people on the retail side or even within the gem trade, might not have any idea of the gem species involved. It was even certed as a Demantoid from one gem lab - whatever one wishes to call it, it is an oddity and rare.

Orangy Topaz Fades Dramatically on Exposure to Light - L. Allen
Brown of All That Glitters had seen large Orangy Topaz online back
in 2005 that was said to originate in Brasil and was supposedly
untreated. Upon seeing this material in Chantaburi, Thailand in
November of 2006, two parcels were purchased. One parcel was
placed into the sun where it proceeded to fade quickly to a beige
color - very attractive, bright sparkly and brilliant gemstones,
but no longer the color that had been originally purchased.
In contacting GIA in California, the other parcel was sent to the
GIA office in Thailand where it was studied in their lab. To read
this story, you may visit the following link:
