Abstract
A method of re-identifying a rough gemstone comprises providing a 3D model of a first rough gemstone; generating a series of virtual 2D silhouette images of the 3D model; processing each 2D image of the series of virtual 2D silhouette images to obtain a dataset associated with the first rough gemstone; and comparing the dataset of the first rough gemstone with an existing dataset of a rough gemstone. Where the dataset of the first rough gemstone and the existing dataset match each other, the method comprises re-identifying the first rough gemstone as the same rough gemstone from which the existing dataset was obtained.

A method of re-identifying a rough gemstone, the method comprising:
- providing a three-dimensional (3D) model of a first rough gemstone;
- generating a series of virtual two-dimensional (2D) silhouette images of the 3D model;
- processing each 2D image of the series of virtual 2D silhouette images to obtain a dataset associated with the first rough gemstone;
- comparing the dataset of the first rough gemstone with an existing dataset of a rough gemstone;
- and
- where the dataset of the first rough gemstone and the existing dataset match each other, re-identifying the first rough gemstone as the same rough gemstone from which the existing dataset was obtained.
