ASET – The Diamond Evaluation Tool

Of all the diamond instruments and analytical devices on the market today possibly the most valuable is the ASET (Angular Spectrum Evaluation Tool). It is simple in concept, easy to use and to understand, and forms the graphical portion of the sophisticated light performance grading system used by the American Gem Society and its Laboratory. The cut quality analysis performed by the AGSL is widely considered to be the most comprehensive and critical of any lab in the world.

Gems of Afghanistan

Afghanistan is a country blessed like few others in its mineral wealth. By some estimates the untapped gemstone deposits in this country are estimated to be $300 billion USD. However, the geological surveying of the country has been less than 10% of the area! Precious minerals, oil and gas have been estimated to be in the 1 trillion to 3 trillion ranges. It’s no wonder why Afghanistan is quickly moving to try to mine and develop so many of these resources.

The Kimberley Process and the Chinese

One of the many presentations, education sessions and panel discussions that were held preceding and during the 2011 JCK show at the Mandalay Bay Convention Center in Las Vegas was a panel presentation organized by the World Diamond Council, called "Diamond Dialogue: The Challenges of a Robust Kimberly Process."

From the Bench: Handcrafting a Garnet and Pearl Necklace

Making a piece of jewelry is always a challenge but it’s easier if you work it through in your mind before you begin, and then convince yourself that this is a good starting point. The gem I am working with is a lovely and unusual cut, a square cushion shaped garnet with a modified step cut crown and multi-faceted pavilion. A stone like this gives me an opportunity to show off a little.The faceting on the top of the stone has a square pattern, so I will start my design by using this pattern on the back of the pendant.
