More than 80 million dollars for a diamond. So many paid in the 2013 year for the oval-cut stone weighing almost 60 carats. Jewel went at auction Sotheby’s. Thus, the most expensive diamond in the world was the sample, which can be confused with spinel, corundum, or quartz. These minerals are often painted in pink, like the famous diamond. By the way, the cost has reached 80 million, including, due to the color. If it is saturated, thus the stone is transparent, jewel give more than its classic counterparts. This is due to the rarity of colored diamonds in nature. Look at how the mineral acquires a brilliance and why it happens not often.
The chemical composition of diamond is carbon. From it, for example, graphite is used in pencils. It’s not so much the element, but in the type of crystal lattice. The diamond it is the most durable in the world, and that makes the mineral is exceptional. Exceptional and conditions of its formation. Required: pressure 50 thousand atmospheres and temperatures of about 1 300 degrees Celsius. These are the conditions at the depth of 100-200 km. In the mantle contains not only carbon. The crystals can get particles of zinc, manganese, copper. It is through them colored diamonds appear. Aluminum ions make the stones blue and dark blue. Nitrogen gives yellow color. The most expensive mineral sold in 2013, the year, owes his color to manganese, pink made jewel. Green color is the merit of chromium.
Brandy paint indicates the iron impurities. And there are chameleons. They are the most rare and expensive. Collection of color changing crystals is presented, for example, in the natural history Museum of London. Here exhibit standard and colored diamonds. Photos on the Internet charm and beckon to visit the capital of England. In stores chameleons almost never to meet. It is worth mentioning about the black diamonds. Their official name is Carbonado. The exceptional stones that owe their color to impurities of metals, and a random set of third-party inclusions. It can be any fragments of other minerals, air bubbles and dirt. Usually, all this makes the crystals bargain. But, if the combination of defects gave black – the stones become valuable and prestigious.
Trace metals are not necessarily distributed uniformly in crystals. Blue diamond, for example, can be really spotty, in divorces. Yellow diamond Canary sometimes happens, and sometimes it is colorless. This reduces the value of the stones. They rejected jewelers. Go to the scrap and crystals, which are mixed and air bubbles. They reduce the transparency. It is expressed in degrees, specified in the certificate for diamonds and jewelry with them. So, a ring with colored diamonds the last 10 degree of cleanliness is not their investment value. Such stones acquire just to have at least some diamond.
Conclusion: only the valuable stones with uniform color, rich color without an abundance of air bubbles. Tiny crystal that meets these requests may be more expensive massive but low-quality sample. Therefore, before you purchase colored diamonds, the specialists ask for the documents to them. In the papers there is another important point – the origin. The stones are ideal, but synthetic. Such is not held in high esteem. Experts chase for natural samples because they are rare and unique.
The era of natural colored diamonds began later time classic options. Long colorful stones been confused with the very quartz, corundum, spinel. Modern experts distinguish more than 250 hues of colored diamonds. So, there were plenty of options with which they can be confused. The turmoil put an end to the creation of the mineralogical hardness scale Mohs and development of a method for chemical and radionuclide analysis of rocks, because the age of most diamonds is not less than 100 million years. This allows you to define the study of the radionuclides. In the 20th century began to see the term “fancy diamonds“. So the experts decided to christen samples of colored diamonds. They became popular in late century. The starting point is considered the 1987-th year. Then, at an auction in New York, posted $1 million for a red diamond weighing 0,95 carat. World realized that it was the era of veneration colorful diamonds. Soon there was a special name for them, advertising companies and famous brands.
In the list of the most-about 10 stones. I almost reached up to glory pink oval diamond “Pink count”. It is square , is inserted into a ring of white gold, sold in the 2010th for 46 million dollars. The crystal weighs in at almost 25 carats. Pink tone and has a “Perfect pink” stone, weighing 14 carats. For the sample paid $23 million. There is one in a series of celebrities and blue chip “Wittelsbach Graff”. The mass of the stone more than 31 carats. In 2008 valued at more than $ 24 million. Crystal found her in the 17th century. In 1664 the second king Philip of Spain 4th gave it to my daughter. Who presented the diamond is now kept in secret, like the name of the buyer jewels. It is only known that the last owner cut the diamond. Carat sacrificed to perfectly cut a specimen, showing all the beauty of its color.
Among celebrities and there are yellow diamonds. Price “Drops of the sun”, for example, equal to 12.5 million dollars. A striking amount of stone 110 carats. Cut teardrop-shaped sample. Found “hero” in South Africa. Last the purchaser for the diamond has shown in 2011 at the auction “Sotheby’s”. Owner, preferred to remain incognito. So buyers of the most famous colored diamonds are not less mysterious than the stones themselves born in the bowels of the planet and marked on its surface by a flow of magma. The origin of this mineral it is igneous. So, he’s hot like a flame, though, and sparkles cold glare.
