The world's first drill in the middle of the big drill is sleeved with a small drill more than 800 m

Original title: the world's first 'diamond in the diamond' appeared in Russia with a history of 800 million years

On October 4, local time, a strange 'diamond in the middle of a drill' was found in a diamond mine in Siberia, Sakha Republic, Russia, according to EURONET quoted the European Union News Agency. This priceless treasure weighs only 0.62 carat and is the first diamond of its kind ever discovered by mankind. It is believed to have a history of more than 800 million years.

It is reported that through X-ray, it can be clearly seen that there is a small drill nested inside the big drill, which can even move freely. Experts estimate that the small drill weighs about 0.02 carat. The diamond was named 'matryoshka'. It is so named because it is similar to the traditional Russian dolls.

This rare diamond was found in the nyurba diamond mine in the Sakha Republic of Russia. Diamond experts have studied it through a variety of methods, including Raman spectroscopy and infrared spectroscopy, as well as X-ray micro tomography.

Experts found that although the structure of this' drill in drill 'is complex, it weighs only 0.62 carat (0.124 g) and the maximum size is 4.8 x 4.9 x 2.8 mm. The internal cavity volume is 6 cubic mm, the internal crystal volume is 1.6 cubic mm, and the estimated weight is 0.02 carat (0.004 g). The inner diamond is plate-shaped and measures 1.9 x 2.1 x 0.6 mm.

The Russian diamond giant Alrosa, who owns the mine, said that the diamond may have a history of more than 800 million years and is unparalleled in the world.

Arrosa spokesman Oleg & bull; Oleg kovalchuk said that it is understood that such diamonds have not been encountered in the history of global diamond mining. This is indeed a unique work of nature, especially because nature doesn't like to leave a space in his works. Usually, some minerals will be replaced by other minerals without leaving a cavity.

According to the research results, scientists put forward hypotheses about the formation of crystals. According to experts, internal diamonds are formed first, while external diamonds are formed in their subsequent growth stage.
