buyer news

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 launched in March 2007 which 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.

In a class all their own – Gemstones worthy of special praise deserve special treatment. The AGTA GTC is proud to announce the JewelFolio™! This hard-bound book contains a wealth of information and is a perfect companion to the perfect gemstone. Where a gemstone report ends, this well-written, beautiful work of art begins.

The factual information of the examined gemstone is illustrated through graphs, inclusion photos and data, but this unique tool also takes the process a step further and features origin information, a pictorial and romantic lore enriching the sale of these important gemstones. In addition to the above, the JewelFolio™ is individually numbered, making each a collector's item. JewelFolio™ is a lavish document for lavish objects and represents an entirely new paradigm in the realm of gemological laboratory reports.
