The diamond has the dubbed the Matryoshka diamond, thanks to its resemblance to the traditional Russian Matryoshka dolls - a set of wooden dolls of decreasing size placed one inside another.
Oleg Kovalchuk, Deputy Director for innovations at ALROSA's Research and Development Geological Enterprise, said: 'As far as we know, there were no such diamonds in the history of global diamond mining yet.
'This is really a unique creation of nature, especially since nature does not like emptiness. Usually, some minerals are replaced by others without cavity formation.'
Based on expert analysis, the researchers suggest that the internal diamond grew first, and the external one was formed during subsequent stages of growth.
Mr Kovalchuk explained: 'The most interesting thing for us was to find out how the air space between the inner and outer diamonds was formed.
'We have two main hypotheses.
'According to the first version, a mantle mineral captured a diamond during its growth, and later it was dissolved in the Earth's surface.
'According to the second version, 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.
The diamond was mined in Yakutia at the Nyurba mining and processing division of ALROSA.
While it has a highly complex structure, the outer diamond only weighs 0.62 carats (0.124 grams), and has dimensions of just 4.8 x 4.9 x 2.8 mm (0.18 x 0.19 x 0.11 inches).
Meanwhile, its internal cavity volume is just six cubic millimetres, and the internal crystal volume is just 1.6 cubic millimetres, with an estimated weight of 0.02 carats (0.004 grams).
The inner diamond has a tabular shape, and has dimensions of 1.9 × 2.1 × 0.6 mm (0.07 x 0.08 x 0.02 inches).
