FAQ

CAP to HPG Conversion

What are CAP files?

CAP is a scan file of a rough diamond made by Sarine Galaxy, a system that looks inside a rough diamond and maps the flaws that are hidden in it, the inclusions, without cutting any windows into the stone. The file holds the images and the data of the scan, from which the three-dimensional model of the stone is built, with the inclusions shown in their places. It is opened in Sarine Advisor, the planning software, where the manufacturer decides how to cut the stone. Sarine is an Israeli company that makes diamond scanning and planning systems.
