Alrosa: Nanometrics on diamonds

2021: Announcement of Technology for Tracing the Origin of Diamonds with Nanomarkets

On July 6, 2021, Alrosa introduced technology for tracking the origin of diamonds using nanometrics. As stated in the Russian diamond mining company, unlike the usual laser engraving, it is impossible to destroy or spoil the nanomark.

Nanometers uniquely identify Alrosa diamonds, distinguishing them from others, including laboratory-grown ones, and allows you to get complete information about their origin.

We are talking about applying a "laser nanometer to the crystal lattice at the atomic level," the report said. The nanometer "is distributed throughout the crystal and cannot be seen without a scanner." With the help of a laser, when applying a label, an effect is made on a gemstone similar to processes that occur in natural conditions "for millions of years," said Oleg Kovalchuk, who oversees the project at the Yakutniproalmaz Institute.

As noted in Alros, according to scientists, as the technology continues to develop, it also looks promising in terms of writing large amounts of data inside the diamond, including media files - up to images and music. By the beginning of July 2021, Alrosa offers its partners diamonds with marks placed in them, as well as reading equipment. Reading the mark takes less than a minute and will be optimized over time, the company said.

Alros added that this technology is first used for commercial purposes for tracing diamonds and diamonds. By the beginning of July 2021, the company is in the process of obtaining patents for it in the main diamond and diamond trading centers, the relevant procedures are launched in the USA, China, Hong Kong, Macau, Taiwan, Britain, Israel, Belgium and India.^[1]
