FOR IMMEDIATE RELEASE GIA Qualifies Sarin's DiaMensionTM HD for Symmetry Grading Kfar Saba, Israel, 23 January 2012 - Singapore Exchange Mainboard-listed Sarin Technologies Ltd ("Sarin") (U77:SI), 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 the Gemological Institute

of America (GIA) has found that Sarin's DiaMensionTM HD has the necessary accuracy and
repeatability to be used to evaluate symmetry.
The DiaMensionTM HD, introduced in late 2009, is the most advanced and most accurate ever measuring system from Sarin's standard-setting DiaMensionTM family. Initially introduced nearly twenty years ago, it is still the most widely used family of systems for measuring a
polished diamond's geometric proportions and deriving its Cut grade. Following the DiaMensionTM HD's introduction in late 2009, a test was done by the GIA to determine whether the system's improved accuracy is sufficient to ascertain data necessary for deriving the polished stone's symmetry grade, a key parameter of the Cut grade, previously
determined only manually, as "the measurement of a round brilliant diamond to evaluate symmetry requires a high degree of accuracy and repeatability for every element of the measurement", in their words. They indeed found that "Sarin Technologies' DiaMensionTM HD tested by GIA, demonstrated an apt capacity to deliver accurate and repeatable symmetry results". They have now concluded, as reported in their article GIA's Symmetry Grading

Boundaries for Round Brilliant Cut Diamonds, appearing in the Winter 2011 edition of the

Gems & Gemology quarterly magazine, that "improvements in the operation and accuracy …
now enable us to also measure … symmetry parameters during the grading process".
