At the world’s largest diamond mining company ALROSA‘s Nyubra mining and processing division in Yakutia region, Russia, a truly rare and first in the world diamond inside a diamond has been unearthed, which is stunning scientists and researchers all across. Something that has never been seen before, a tiny diamond weighing a mere 0.124 grams and admeasuring just 1.6 cubic millimeters freely rattles inside another diamond measuring 4.8 by 4.9 by 2.8 millimeters and weighing around 0.62 carats – the size of a lentil.
The “double diamond” resembles a traditional Russian Matryoshka doll, also known as ‘Nesting doll’ after which it has been named. Found during sorting process by Yakutsk Diamond Trade Enterprise, the Nesting Doll diamond was then turned over to ALROSA’s Research and Development Geological Enterprise where several studies were conducted including X-ray microtomography, Raman, and infrared spectroscopies.
What is puzzling scientists is how this implausible formation was developed, especially the air cavity present in the outer diamond. While several hypothesis are being formed, there is still not a clear explanation behind this uniqueness. Considering the rarity of the stone, it is going to be difficult to even estimate its worth.
However, in most media reports, it is mentioned that this unique creation of nature is believed to be over 800 million years old!! In all probability in this case also, like in case of all other mined diamonds, there is a general misconception that diamonds take millions or billions of years to form.
