This 2-in-1 diamond was found at a mining site in Siberia, Russia and was named the Matryoshka Diamond which took after the name of Russia’s traditional Matryoshka doll.
In reality, most of the diamonds discovered in the wild have holes or other kinds of materials stuck inside. But according to ALROSA, a leading diamond mining company in Russia, Matryoshka is extremely rare as it is a 2-in-1 diamond with a diamond within another diamond.
The outer gem of the diamond is about .62 carats. Its dimensions are 4.8 x 4.9 x 2.8 mm.
The inner gem is a lot smaller, roughly .02 carats. Its dimensions are 1.9 x 2.1 x 0.6 mm.
In the mining process, miners discovered that there’s something strange about this particular diamond. Right after that, it was sent to the Research and Development Geological Enterprise of ALROSA for assessment. There, the scientists used the Raman Spectroscopy technique as well as X-Rays to observe the structure of this unique diamond more clearly.
Oleg Kovalchuk from the Research and Development Geological Enterprise said that the most interesting for him and the team was to find out the way the air space between the outer and inner diamonds was formed.
The scientists have several ideas regarding the forming process of this 2-in-1 diamond.
“a layer of porous polycrystalline diamond substance was formed inside the diamond because of ultra-fast growth, and more aggressive mantle processes subsequently dissolved it. Due to the presence of the dissolved layer, one diamond began to move freely inside another, just like a matryoshka nesting doll," according to one of their hypotheses.
The diamond is estimated to date back over 800 million years ago, although that isn’t verified yet. Bloomberg reported that the researchers will send this diamond to the Gemological Institute of America so that it can undergo more analyses.
Because of its rarity, the company hasn’t estimated its worth.
Oleg Kovalchuk shared that in the history of diamond mining across the world, there has been no other diamond that has this uniqueness. He said, “This is really a unique creation of nature, especially since nature abhors a vacuum. Usually, in a case like this, the minerals would be replaced by others without forming a cavity."
