The last stage in manufacturing is the quality control, which inspects the diamond by facet to make sure the desired result has been achieved.

Once that is determined, an in-house gemologist will set the grade of the diamond by analyzing its size, color, clarity and fluorescence, before being valued.  This is achieved using various tools.

The virtual 3D simulation of the Advisor program in the DiamMark-Z-Eye allows for the user to visualize how a polished diamond would look like based on the make decided by the already as of the rough stage. This simulation is important to visualize the brilliance and fire in the diamond both in the planning to be polished and as a final outcome.
