Introducing the JewelFolio™
We have the pleasure of working with some of the most beautiful and rare objects on the planet, creations of wonder and awe. While laboratory documents serve to provide important factual information, wonder and reverence are absent.
Enter the JewelFolio™
The AGTA GTC JewelFolio™ is a custom-built, one-of-a-kind document for a one-of-a-kind jewel. Each JewelFolio™ consists of a hardcover cloth or leather-bound volume that will be a companion to an individual jewel. Volumes are based around a type of gemstone and/or origin.
The following types of JewelFolio™ are now available:
- Kashmir sapphire
- Burmese sapphire
- Burmese ruby
- Colombian emerald
Additional volumes are in preparation.
Contents
Every JewelFolio™ consists of approximately 32–36 full-color pages and features the following:
- History, legends and lore
- Modern and antique maps and photos
- Color photos illustrating both rough and cut gemstones and inclusions
- Detailed testing information on the specific specimen, including advanced tests
- Macro and microphotographs which will separate the specific specimen from all others
- Reproduction of the standard AGTA GTC Origin Report
- References for further reading and care instructions
In addition to the above, the JewelFolio™ is individually numbered, making each a collector's item.
Cost
JewelFolios™ are lavish documents for lavish objects, and represent an entirely new paradigm in the realm of gemological laboratory reports.
- Cloth-bound: $750 (nonmembers: $1250)
- Leather-bound: $950 (nonmembers: $1450)
All fees are in addition to the cost of preparation of a standard AGTA GTC Origin Report (for a single gemstone). Additional stones will be quoted on request.

Tanzanite Grading Reports
The AGTA Gemological Testing Center is proud to announce that it now offers Tanzanite Grading Reports in accordance with the Tanzanite Quality Scale™. The Tanzanite Quality Scale™ is a tanzanite specific, internationally recognized tanzanite grading system which has recently been launched in North America in March 2007 and Hong Kong in September 2007. The Tanzanite Foundation's vision is to establish a universal standard for grading tanzanite so as to facilitate for trade and consumer confidence, encourage a more comprehensive and consistent understanding of tanzanite's qualities and rarity, as well as encourage the development of a more formalized industry.
The AGTA is a leading industry force in the promotion of colored gemstones and provides education and research as an integral part of their mission and purpose. In 2002, the AGTA selected tanzanite as a December birthstone, adding it to a list of birthstones unchanged since 1912.
Gabriella Endlin, Technical Director of the Tanzanite Foundation comments, "We are extremely gratified to enter into this strategic cooperation with the American Gem Trade Association and its Gemological Testing Center. Their support of our vision for a universal, consistent tanzanite grading system is essential. The AGTA has the expertise and market positioning to play a key role in achieving this unprecedented goal."
AGTA GTC Laboratory Director, Dr. Lore Kiefert said, "I am very excited about this collaboration. The Tanzanite Foundation's vision is something very well worth sharing, and we are proud that Tanzanite Foundation has selected us to do so. Tanzanite is consistent in its properties making it a perfect gemstone to receive a grading report. We are looking forward to a continued collaboration with the Tanzanite Foundation."
The Tanzanite Quality Scale™ grades according to specific standards under the 4 C's criteria of Carat Weight, Color, Clarity and Cut. A fifth "C" stands for Confidence. Tanzanite Quality Scale™ grading certificates issued by AGTA GTC will provide the assurance that the tanzanite inspected is accurately graded, authentic and of natural origin, from the world's only known tanzanite source situated at the foothills of Mount Kilimanjaro in Tanzania, East Africa.
