Products for measuring and grading of polished diamonds

DiaMension™ / DiaExpert™ Platform

DiaMension™ (see picture above) is an assessment system for the cut of the polished diamond. It enhances diamond manufacturing and diamond grading efficiency in all phases of production by combining computerized machine vision and advanced three-dimensional image processing technologies to evaluate and display geometric properties of stones and present accurate on-screen proportion and symmetry measurements.

DiaMension™ was introduced in 1992 and many gemological institutes worldwide, such as the GIA, have acquired the DiaMension™ for use in their certification process. Successive generations of the DiaMension™ have incorporated additional features, such as more accurate imaging and measuring, recut software which is used to evaluate the potential benefits of re-cutting and re-polishing a polished diamond, and "finger-printing" software. Subsequent models also address the varying needs of different market segments (manufacturing, wholesale trading, retail) such as portability, stone sizes and pricing.

DiaVision™ (see picture on the right) is an enhanced version of the software in the DiaMension™, which enables the measurement of the cut of the polished diamond by analysing the proportion and symmetry of the polished diamond.

It is able to measure virtually any shape (round or fancy), a wide range of sizes (up to 70 carats) and accurately quantifies all the angles and facets of the polished diamond. The software can be set to grade the various cuts according to major gemological laboratories' grading standards and provides reports of the grades.

It incorporates enhanced modelling accuracy and proprietary software, enabling both inspection and documentation of previously unattainable data, as well as the simulated quantification of new parameters defining the beauty of the polished diamond by the brilliancy, scintillation and fire. It also offers the user a realistic threedimensional model of the diamond cut and has a photorealistic viewer for assessing the light performance of the measured diamond.

It includes a new visual editor for quickly customizing on-screen views of the diamond's appearance, labels and full-sized reports for printing. It is an add-on software module and is compatible with all our hardware platforms including our DiaMension™series of diamond grading machines, DiaScan and Brilliant Eye.


Brilliant Eye is designed to increase the consumer confidence in the quality of the stone, providing the consumer with information on the stone (including an animated threedimensional display of the stone) and generating an accurate measurement report endorsed by major gemological laboratories worldwide. This system assists the diamond merchants and jewellers in sales to the end customers. It is based on the same technology as the DiaMension™.

DC 3000 Colorimeter

The DC3000 Colorimeter (see picture above) is a computerized colour measuring system for polished diamonds up to 20 carats in size. It is able to measure all grades from a D (optimal colour) to a Z (inferior colour) and provides an accuracy of up to a half grade.


The SAM software allows the user to scan a gemstone and save its data as a standard stereo-lithographic file using our machine. This enables the user to incorporate the exact stone dimensions into a three-dimensional CAD program for the jewellery designer, thus aiding its incorporation into the final jewellery design.

It is capable of measuring virtually any shape (round and fancy), in a wide range of sizes and measures all the angles and facets, including the upper and lower girdle of the stone. It has an easy to use graphical interface and is a simple two-step operation (scan and save). It is compatible for use with our DiaExpert™, DiaMension™and DiaScan hardware platforms.

The Sarin Web Viewer is a freely distributed program for viewing Sarin files, which may contain stone reports, measurements and three-dimensional stone models without the need for our machines. It enables users to inspect the stone in detail without actually physically holding the stone. It is designed as an aid for our customers to market their stones on the Internet. Our web viewer can be operated using standard software programs, like Microsoft Windows™
