(Kitco News) - Russia's ALROSA, a leader of the world diamond mining industry, announced today that it has introduced a ground-breaking diamond-tracing technology using non-invasive laser marking.

Unlike traditional laser engraving, this laser marking cannot be destroyed or polished off. The company said that this technology distinguishes ALROSA's diamonds from other ones, including lab-grown, and allows them to be uniquely identified, providing detailed information about the diamonds' origins.

Additionally, unlike other tracing methods which are based on keeping a digital copy of the diamond, ALROSA physical nanomarking allows the precious stone to be identified with 100% accuracy. It also differs from other engraving technologies which mark closer to the surface of the diamond. ALROSA's laser nanomark is imprinted inside the crystal lattice, across the atomic structure of the entire diamond, making it invisible without a scanner.

The mark is a three-dimensional code linked to the ALROSA Provenance platform. It offers in-depth information about the diamond's origin and characteristics, as well as a unique identification number, photo, video and details about how it has been cut.

Scientists believe that, as the technology evolves, it is likely to become an important way of embedding large amounts of data within the diamond, including media files, images and music.

The company said it is offering its partners marked diamonds and the equipment to read them. Scanning the code takes less than a minute and will eventually be optimised to ensure even greater efficiency.

Patent research has confirmed that it is the first time this technology is being used for commercial purposes to trace rough and polished diamonds. ALROSA said it is currently seeking patents in the world's major diamond-trading centres, and has started application processes in the US, China, Hong Kong, Macao, Taiwan, the UK, Israel, Belgium and India.
