GIA verifies estimated cut grades from improved DiaVision

Singapore Exchange Mainboard-listed Sarin Technologies Ltd, a worldwide leader in the development, manufacturing and sale of precision technology products for the planning, processing, evaluation and measurement of diamonds and gems, is pleased to announce that an in-depth comparison evaluation performed by the Gemological Institute of America (GIA), between their internal methods to determine the Cut grade of a round brilliant diamond and Sarin's new implementation of the Facetware database in Sarin's measuring systems, shows highly compatible results between the two methods.

GIA introduced its new standard for Cut grading of round brilliant diamonds in 2006 and uses a proprietary software package to assess it a combination of proportion data measured by Sarin's DiaMension, an analysis of variations affecting brilliancy (so called painting or digging out), and other visually evaluated parameters - polish, symmetry, girdle minimum and maximum and culet size. Sarin has recently completed improvements to the implementation of the optional Facetware package in its DiaMension and DiaVision products to exactly match GIA's methodology for calculating the proportion parameters, evaluating the brilliancy variations, and predicting the girdle and culet sizes.

To evaluate compatibility, the GIA measured more than 14,000 stones, randomly selected during their diamond grading processes at various geographic locations, using Sarin's DiaMension platform with version 5.0 of the DiaVision software. The measured data were processed twice – once by the GIA's internal software and once by Sarin's software. Comparison of the results showed that 99.8% were identical for the proportion-based and brilliancy-variation aspects of the cut grade evaluation, a truly significant improvement over cut grade estimates from previous versions. In addition, prediction of the effect on the cut grade from girdle minimum and maximum and culet size showed 98% agreement with reported descriptions of these parameters.

The GIA concluded that its reported cut grades and Sarin's estimated cut grades measured by DiaMension and DiaVision version 5.0 or later are highly compatible.

Uzi Levami, Chief Executive Officer of Sarin, commented “Sarin's customers can now be sure that when they use DiaMension, DiaVision and the embedded Facetware database, they will, with very high probability, get the same Cut grade as given by the GIA, provided that their systems are properly maintained.” He further noted that the recently introduced DiaMension HD will provide even better accuracy, as Sarin continues to strive for perfection.
