The diamond with another one moving freely inside was unearthed at the Nyurba Mining and Processing Division. 
According to scientists, diamond may be over 800 million years old. Despite its complex structure, it weighs only 0.62 carats (0.124 grams) and has maximum dimensions of 4.8 x 4.9 x 2.8 mm. The internal cavity volume is 6 mm3 and the internal crystal volume is 1.6 mm3 with an estimated weight of 0.02 carats (0.004 grams). The inner diamond has a tabular shape and dimensions of 1.9×2.1×0.6 mm.
Specialists of the Yakutsk Diamond Trade Enterprise discovered this unusual diamond during a sorting process.
It is yet to be discovered how exactly such a diamond was formed, but it is assumed that both stones were formed simultaneously.
