This project aims to improve the safety of INCM's contrasting marks in precious metal artefacts (the precious metals are officially designated: gold, silver, platinum and palladium), making them unique and unable to be copied and faked. One of the objectives of this project is to allow the test of authenticity of the object to be made by goldsmiths, merchants and consumers equipped with verification instruments with a high level of ubiquity and therefore relatively easy to handle, inexpensive and simple to acquire, namely basic lenses or smartphone cameras.
