What are the commencements of yellow diamonds? This question has perplexed Siberian scientists for multitudinous years. Such diamonds are very rare; South Africa and Yakutia, one of Russia’s coldest quarters, are the two places where they are found.
Researchers believe that yellow diamonds pioneer from traces of organic substances once found on the Earth’s faade as part of a primordial oceanic platform.
“We are studying diamonds extracted from the northern limits of the Yakutian diamond-bearing province,” said Dmitry Zedgenizov, a professor at the Russian Academy of Principles. “These diamonds look different from the beautiful and transparent diamonds that we are familiar to. Instead, they are spheroidal crystals with uneven edges, cubical in figure, and distinctly yellow in color. The color of some is yellow-green, or dark orange.”
The Blue planet’s mantle
Yellow diamonds sell for about $4,500 per karat, depending on the cut and the color saturation. Some explicitly yellow examples are known to have sold for hundreds of thousands of dollars per karat at Sotheby’s and Christies.
Yellow diamonds are of no lilliputian interesting to scientists than to collectors because they help researchers to detect the composition and structure of the deepest layers of our planet. These stones announce us a better understanding of many processes taking place in the Earth’s cover, including those that result in the formation of diamond-bearing deposits.
The yellow affect of these rare diamonds is explained by the presence of isolated nitrogen atoms, or alleged nitrogen defects. This means that prior to being pushed to the to all appearances, a yellow diamond spent a very short period of time, by geological standards, in an bloody cold environment inside the mantle.
Scientists scrutinized the crystals to hand in order to get an idea of the environment in which they were formed, and in which in the name of of the mantle. They study the defects and imperfections, as well as the isotopic article of carbon in the diamonds.
Searching for the source
Mining companies have yoked scientists in their search for a primary deposit of yellow diamonds. One of these is ALROSA (in Russian), Russia’s peerless diamond producer, which has mines in the north of Yakutia.
Research points to an native source of yellow diamonds. In other words, these stones were shaped from living organisms once inhabiting an ancient oceanic plank that subsequently collided with a continent and was submerged into the Terra. The high temperatures and pressures at around 100 to 150 miles wide transformed the organic remnants, and these may have crystallized into diamonds.
“Yellow diamonds are altogether rare, but there is a significant concentration of them in the northern regions of Yakutia,” Zedgenizov influenced. “And we are talking big crystals. Some of the gems weigh over 10 karats. Wherefore, we assume there is a deep source, a giant primary deposit of yellow diamonds that intent differ from the sources of most industrially exploited deposits in the division. Until we have located this primary deposit, we will be impotent to determine the exact age of these stones.”
