CUT- THE MYSTERIOUS FOURTH “C”

Known for decades only by diamond cutters and diamond professionals, the mystery of diamond proportions has been unlocked by modern technology.

With the aid of the latest state of the art equipment and software, Sarasota Gem Lab is able to visually demonstrate, photograph and describe the effect of different diamond proportions on brilliance, fire and scintillation.

Instrumentation like the IdealScope developed by Garry Holloway of Australia and Hearts & Arrows
viewers developed by Japanese gemologists allow the light return perfomance and optical symmetry to be viewed firsthand by the layperson & gemologist alike.

The cutting edge DiamCalc software developed by the Russian scientists Sergey Sivovolenko of Octonus and Yurii Shelementiev of Moscow State University (among others) quantifies this light return in an easy to understand report produced by Sarasota Gem Lab.
