How It Works

gp_example1.jpeg

The green pattern is the GEMPRINT® of one diamond and the red pattern is the GEMPRINT® of another diamond. The computer rotates the pattern to find the best alignment and then marks the matching points. The sample on the left is only a 7% match and the one on the right is only a 3% match. Just like in fingerprint matching, positive identification requires a high percentage match.

This is an example of a matching GEMPRINT® pattern of the same diamond. The computer rotates the two patterns (red and green) to find the most accurate alignment, and then marks the matching points (image on right). This is a 99% match.
