Diamond rattling inside another diamond unearthed in Russia

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.

As Tom Chatham points out “Diamonds do not take “billions of years to form or crystallize” in the earth and nothing scientific backs up this statement. Every crystal has an optimum growth speed, which can be slowed up and/ or speed up a little but not by much. A convincing argument against this “billions of years to form” premise is the unlikely event of conditions remaining stable and consistent where diamonds no doubt grew, 150 miles down. This is a growing trend of switching the AGE of diamonds found on the surface of the earth, which is likely in the billions of years, to the more romantic notion that it takes “billions of years to grow” in the ground… Carbon at high pressure and temperatures just wants to be diamond. Furthermore, it is the only gemstone that is 99.995% carbon, only one element… Hundreds of millions of years ago, the earth spit out diamonds through many pipes, quickly cooled (or else they would turn to graphite or carbon dioxide) and there they sat for millions of years!”
