GIA Upgrades Cut Grade Measuring Systems

The Gemological Institute of America (GIA) has begun replacing its current DiaMension systems with Sarin's new generation of measuring devices – the DiaMension HD, Sarin said in a news release.

DiaMension HD uses a high resolution digital camera, specially designed interchangeable optical lenses and a unique lighting module for unmatched precise scanning and optimal accuracy across a wide range of stone sizes (from 3.0mm to 28.0mm).

According to Sarin, GIA’s initial evaluation of the DiaMension HD system has found that it generates high fidelity 3D modeling and improved precision for the measurement of polished diamonds. The phased upgrading will allow the GIA to further evaluate the performance of the DiaMension HD and explore its suitability for measuring polished diamond symmetry features.

DiaMension HD is supported by Sarin’s DiaVision software. In July, Sarin said that GIA evaluated the software and found that it provides estimated cut grades, which are highly compatible with the GIA's own reported cut grades.
