Russia develops counterfeit diamond solution

Russian scientists have come up with a method that can help distinguish real or fake diamonds.

Researchers at the Institute of Physics of the Institute of Physics at the Russian Academy of Sciences have proposed at the same time two methods for accurately marking diamonds in micro-size. This invisible marking can be accomplished using femtosecond laser technology , which generates super-short momentum for 10-15 seconds.

Laboratory staff, Alexey Levchenko, say the laser waves will produce a defect in the crystal lattice by electrons or currents of any high energy particle.

These defect points will form the shape needed to mark. The missing points can be filled with nitrogen atoms in the diamond. As a result, these atoms start to emit light. This can be read in the diamond in the microwave.

Russian scientists have successfully tested the method and registered the copyright.

The second marker also uses femtosecond laser technology, but instead of creating defects, diamonds form carbon-like spots called amorphous . These dark microscopic spots can be seen in the microscope, but the naked eye is not visible.

According to senior researcher Sergey Kudryashov, Russian scientists have even made a three-dimensional microscope sign.

The head of the laboratory, Andrey Ionin, said 80% of the world's diamonds were used for technical purposes, and the remaining 20% were of good quality for jewelry. Islands get a lot of profits when faking diamonds.

Therefore, the development of diamond marking methods that no one sees and does not damage them is one of the most important tasks of the jewelry industry today.
