Diamond Tips by Excel Diamonds

Since we are often asked whether we use the Isee2 diamonds technology in tandem with our plethora of scientific info. for our listed diamonds, i'd like to post here with my documented reservations regarding the science behind this machine.

Although the company behind the Isee2 technology is a reputable company manufacturing beautiful ideal cut diamonds, I expressed reservations in that blog on Diamond Vues regarding the ability of the machine itself to be used as an accurate measure of a diamonds brilliancy, given that it was developed for use with this companies own signature diamonds.

I posed some legitimate questions and engaged in a very civil and meaningful discussion with the chief engineer for the Isee2 technology who had much to add and his own perspective to share.

While I am certainly not the final arbiter on the value of a scientific machine, I can only express my own cogent and salient points regarding our position (and that of many others in the industry) and to let the customer reach his/her own conclusion, re: the value of this machines measurement output.

Many consumers are constantly asking us for advice on their prospective diamond purchases.

They list their candidates and provide the diamond's numbers off the Lab reports and in some cases list additonal Cut information derived from
either the Sarin (www.sarin.co) or Megascope (www.ogisystems.com) machine.

For round brilliant diamonds it is easier to advise against purchase
when the numbers clearly indicate an overly shallow or deep stone that will display poor to mediocre light performance.

The difficulty presents when consumers provide "numbers" that look very good and/or ideal. The term "ideal" for the purposes
of this article is used in the context of the Marcel Towlkowsky Ideal-Cut, the "numbers" calculated by Towlkowsky
in the late 1900's to result in a diamond that displays superior light performance.

The Brilliancescope, manufactured by Gemex Systems (www.gemex.com) is an imaging spectrophotometer that measures
how well a diamond refracts and focuses light.

Past all of the numbers, a diamond's beauty is the result of how it returns light to your eye. When a diamond's facets have been cut to the correct size, angle, and aligned correctly, they act as mirrors, refracting light
with great intensity and with an even distribution across
the entire surface of the stone.
