Instead of "I think this is a" we can now say "measurements on this make it fall in this range". We use laser light to measure the amount of brilliance, and computer comparison technology to analyze cut grade, and color grading on a numerical scale (i.e. "if it falls between x and z then it is this color"). Most of these are using light in some form, either through the stone or off the stone surface to give read outs analyzed by computer. These methods are repeatable and reliable.

Video Microscope

The SpeckFinder Digital Computer Microscope by Dazor is a visual imaging system used to see precise details of nature's inclusions within diamonds and gemstones. It is the next step up from the microscope. You will be able to see what the appraiser sees in real time.

Laser ASET

The AGS ASET is a device that allows the viewing of the color-coded mapping from where a diamond draws light. This will be a buzz in the industry very soon as many highly graded diamonds with excellent cut have very little optical symmetry. What does this mean to you? One is a rock that reflects very little light and the other has the fire to blind people across the room. Which one do you want? This device can measure this and explain on computer screen and printed reports why one diamond has it and another doesn't. Light can "Leak" out of a diamond. The ASET machine uses laser light to show the patterns of brilliance and leakage.

Cut Grade Analysis

This is done by passing light around the stone so that a "shadow" can be made. The turning platform takes many "pictures" of the stone and extrapolates the information into the shape. Very accurate and precise measurements can be made from this method. Now your stone can be contrasted to information in the database and conclusions can be made about the cut of your diamond.

Stone Color

Now we use a special designed "meter" to assess stone color. Light is passed through the stone and analyzed for color content based on its spectral color. This method measures the frequency of the light and reports back with the letter assigned to the frequency range reported. Amazingly accurate and fast. This is science at its best in a practical application.

This information is so new that most people in the retail jewelry stores won't even know about it. The Jewelry Judge stays on the front edge of the technology. We will be putting up more on this technology as it is being developed.
