What is a non destructive technique for examining fingerprints?
The inherent fluorescence method is usable on any surface, including surfaces that cannot be treated with powders or chemical methods, and may reveal latent prints that are not revealed by any other method. Like visual examination, examination by inherent fluorescence is non-destructive.
What is diamond fingerprinting?
Like a snowflake, each diamond contains a unique size, shape, and formation of inclusions, and these characteristics serve as a natural fingerprint that can help identify it and categorize its diamond clarity.
Can you leave a fingerprint on a diamond?
Dirt and grease will transfer from finger to diamond, and the stone will rapidly lose its sparkle. If you touch the diamond, use a clean polishing cloth to remove fingerprints and grease.
Do diamonds hold fingerprints?
Inclusions are what make a diamond unique. Just like no two people have the same fingerprints, the same can be said about diamonds and inclusions. A diamond's inclusion can be a great identifier.
