Abstract
An assembly for analyzing a light pattern caused by refraction and reflection at a precious stone, comprising a light source for illuminating the precious stone, a retaining device for retaining the precious stone, a diffusing screen for imaging the light pattern, and a camera for recording the light pattern imaged on the diffusing screen. The assembly comprises a semi-transmitting optical element for deflecting, in a direction of the precious stone, light emitted by the light source and transmitting the light refracted and reflected at the precious stone.
