The Most Famous Diamonds of The World:

It is no secret that along with the history of mankind, the history of diamonds also formed. Some diamonds were owned by emperors, others have been famous for their size, shape, color. This blog page of our website is dedicated to such famous diamonds in the world.

1-Diamond "Kohinoor" :

Once the diamond with the name "Kohinoor" (in the lane "Mount of Light") was the largest diamond in the world. Initially, its owners were the rulers of India, today this diamond is part of the precious crown of the British royal family. For the first time a huge diamond was mentioned in the annals of the early 12th century, then in 1526 the diamond was found in the treasuries of the Great Mongols. The diamond acquired its name in 1739 after it fell into the hands of the Persian Shah Nadir, who conquered the capital of India. Kochinor, and in the translation “The Mountain of Light”, stayed in Punjab and Afghanistan before becoming the property of the East India Company in 1849. The company, in turn, brought a gem as a gift to Queen Victoria of Great Britain. In the UK, Kohinoor acquired its modern look. The original location of the gem, and where it was cut, is still unknown. Most likely, this place was India, because the minerals of the rulers of this country are famous throughout the world. The diamonds of Orlov , Shah , Indore pears, Arkots, Dariya-i-Nor, as well as Kohinor today are the ornaments of private and public collections in different parts of the world. The third name of the gem is "the eye of the storm." For all the time of its existence, the gem has never been bought or sold, but managed to change many influential owners. At the same time, the “Mountain of Light” never differed in its special beauty, the magic of attraction of this mineral consisted in something else. It looked like a diamond Kohinor until 1852 Most of the legends tell that Kohinor was discovered more than 4,000 years ago in India. According to Indian legend, a charming child was found on the banks of the Yamuna River. On the child's brow, the stone shimmered and glistened - Kohinor. And the first historical mention of the mineral appears in the oldest "Notes of Babur." As one of the descriptions says, after the arrival of Mohammed Babur to Agra, such a valuable gem was handed to him by the Indian king, Vikramadity. Events date back to the spring of 1526. After that, for two centuries, the mineral was called "Babur's diamond". After the transfer of the golden throne of the Great Mongols to Nadir Shah, one of the servants of the harem of the former Shah Mohammed, wanting to become the favorite of the new Shah, revealed to him the place where Kohinor was: Mohammed constantly wore a precious gem in a turban on his head. Then Nadir Shah invented a trick: he ordered to arrange a grand celebration, coinciding with the return of the throne to Mohammed Shah. During the festival, Nadir-Shar, as a sign of eternal brotherhood and friendship, suggested that Muhammad exchange turbanas. He, of course, did not dare to refuse. During the night after the exchange took place, the cunning Nadir Shah entered his apartment, unrolled a turban and, of course, found the desired diamond in it. Later, together with the stone, called “Kohinor”, ​​the shah returned to Persia, where he was expected to be betrayed, mutinous, poisoned and, as a result, he would die by the hand of his own military leader. So began to look like the diamond Kohinor 1852 In the 19th century, the flag of the British Empire was raised in Punjab. One of the terms of the contract was that the precious stone, called Kohinor, is donated to the Queen of England. So, the famous gem on a warship left Bombay, apparently forever. However, as you know, the stone did not impress the queen at all, and it seemed to the royal nobility that the diamond was too dull. Even the fact that at that time the mineral still had a gigantic mass - about 109 carats - did not save the situation. After the arrival of the stone in England, Prince Albert, together with the jeweler Sebastian Gerrard, stated that the gem has an irresistible diamond shape of a rose and that the new cut will make Kohinor begin to play again. They decided to turn to experienced mineral cutters. In order to re-cut Kokhinor, a small machine with a steam engine was installed. After 38 days of painstaking work, which cost the British treasury a round sum, the mineral was almost spared from yellowness, and became lighter. Thus, a modern oval-shaped diamond, weighing 108.93 carats, appeared. In the process of recutting, a diamond lost 43 percent of its weight. The expediency of this procedure caused a storm of criticism and doubt, since the diamond, with its original Indian cut in the shape of a rose, was of tremendous cultural and historical value. In 1853, the magnificent diamond Kohinor became an adornment of the royal tiara, which already included more than two thousand precious stones. In 1937, the gem was transferred to the crown, which was made similar to the precious crown of Victoria, Queen of England. Cochinor was inserted into the Maltese cross, located in front of the new headdress of the rulers of England. Today, one of the most famous diamonds, Kohinor, is in the corona, which crowned Elizabeth. The product is stored in the Tower of London.

2-Diamond Great Mogul:

The imperishable symbol of India, striking in its magnificence and tragic history, the Taj Mahal is the brainchild of the legendary ruler of the Mughal Empire, Shah-Jahan. But not only the glorious deeds and the majestic tomb brought to our day the name of a powerful ruler.In the middle of the 17th century, in the very heyday of the emperor's rule, the diamond mines of Golconda revealed a treasure to the world, the likes of which India had not yet known - a diamond weighing 787 carats or 900 Indian rati. Up to the beginning of the 20th century, the stone was considered the largest of those found in nature. Bloody history Diamond Great Mogul, illustration from the encyclopedia "Nordisk familjebok" Such an amazing treasure could not hide from the gaze of Shah-Jahan, who knew a lot about everything beautiful, especially jewelry. It is not surprising that the stone that adorned the treasury of Raja Golconda was stolen by the perfidious servant Mirgimola and ran under the protection of the emperor, seducing him with a great gift. So begins the story of the legendary diamond “Great Mogul” full of secrets. According to legend, the diamond became the cause of hostility within the royal dynasty, and the constant intrigues and conspiracies between relatives created a bloody halo around the stone. Aurangzeb, who took the throne from his father Shah-Jahan, became the new ruler of the Mughal dynasty and, of course, seized an amazing diamond. Only the best craftsman, who became the Venetian jeweler Hortensio Borghis, could entrust the cutting of the true natural miracle. Having been in the hands of an Italian, the stone has almost tripled in size, and the faceting has become the traditional form of roses in India. It is believed that the work of the master did not suit Aurangzeb, because “the Great Mogul”, as the diamond has since been called, has significantly lost weight, besides it had a barely discernable speck inside and a defect on the bottom. As a result, Borgis did not receive any payment for his work, having lost the advance payment, which was a fabulous sum of 10,000 rupees for those times. The only European, besides the jeweler, who saw the Great Mogul alive is considered to be the Frenchman Jean-Batista Tavernier. The French traveler, kindly invited to the court of Vladyka Aurangzeb in 1655, described the magnificent diamond in his Indian notes with sketches. According to him, the stone weighing about 280 carats was like a half of an egg, had a bluish tint and a rose-shaped cut. It seems that the Frenchman was the last official to see the diamond, because the fate of the greatest Indian treasure is covered in mystery. It is believed that the stone was the property of the Mughal dynasty until 1739, but due to the plundering of Delhi by the troops of Nadir Shah and the brutal massacre perpetrated by the Persians in the capital, was stolen along with the rest of the treasures. The references to the bloody diamond can still be found in the Persian chronicles for the period before the murder of its last owner in 1747, but after the death of Nadir Shah, the traces are lost, and the fate of the treasure forever becomes a mystery. Where did the legendary diamond go? For a long time, the fate of the stone did not give rest to the scientific minds and jewelers, different versions were born. Some claimed that the Indian diamond was divided into two equally legendary stones “ Kohinur ” and “ Orlov ”. And the gemologist Tennan did believe that there were three stones at all: a diamond, called the “Big Table”, was added to the decoration of the British crown and the wealth of the Russian Diamond Fund. According to the version peculiar, for example, to the Russian mineralogical scientist Fersman, it was believed that the “Great Mogul” and the “Eagles” were one and the same stone, and the difference in weight was due to Tavernier’s mistake in terms of carats. The hypothesis is confirmed by the external similarity of diamonds. Although the most plausible version can be considered recutting the "Great Mogul" in the "Eagles", as a result of which there was a weight loss.

3- The Jonker Diamond:

Jonker, as he is sometimes called, is named after the prospector Jacob Jonker, who found him on his land. It happened in January 1934 in South Africa, in the Transvaal. At the time of discovery, he was the second among the largest diamonds, and today occupies the eighth position. This completely transparent stone was rounded with a small chip on one side, weighed 726 carats and was distinguished by a bluish tinge. The size of the raw stone was 63 mm long and 38 mm wide. For 315 thousand dollars a diamond from Jonker bought the association of diamond producers. And next year, he was very successfully resold to the future king of diamonds - Harry Winston, then little-known American, for 700 thousand dollars. Winston was very risky, because the money was rather big, and no one could predict how the stone would behave during processing. The insurance company, of which Harry was a client, refused to pay the risk of failing to cut Jonker. The chances that a diamond will not crumble into the smallest particles when trying to split it were estimated at 50%. Lazar Kaplan was invited to conduct a dangerous operation. This hereditary jeweler from New York spent a year studying the structure of the stone, before starting to cut. As a result, 12 diamonds were obtained (total weight 370.87 carats), they all received the name Jonker with the corresponding number from I to XII. All of them, except for the largest, sold with a multi-million profit. The largest (142.9 carats) diamond, which received an emerald cut of 58 facets, was left to a successful businessman. First, he flashed in a luxurious necklace of platinum, but later (in 1937) was subjected to repeated processing. He received a new, more elongated shape, increased to 66 the number of its faces, and began to weigh less - 125 carats. In 1949, Winston still sold the diamond to the king of Egypt. The upheaval in 1952 led to the flight of King Farouk I, and with him all the valuables in the royal treasury were gone. There is no reliable evidence, but it was said that Jonker I was sold by the exiled king for only 100 thousand dollars, other sources claimed that for some time he was in the possession of the Queen of Nepal Ratna. The last mention of this perfect diamond dates back to 1974, when, according to rumors, it was acquired by a businessman from Hong Kong for $ 4 million.

4- Cullinan Diamond:


In January 1905, the largest diamond in the world, Cullinan, was discovered at the Premier mine in Transvaal (South Africa). The gem weighed 3,106 carats, and, apparently, broke away along the soldering plane from the crystal, which had twice the size. The story of how to find the largest natural diamond in the world, has long been overgrown with various fictions. There are several versions telling of finding such a gem of such an impressive size. One of them tells that the manager of the African mine, Frederick Wells, while conducting the evening round of the mine, noticed a strange brilliance at a height of about 9 meters on the wall of the quarry. From there, the mine workers extracted a large diamond, the dimensions of which were 10x5x6.5 centimeters. It was established that this diamond is only a fragment of a much larger stone, although it was not possible to find it. Photo by Thomas Cullinan (leftmost) The find was named after the owner of the mine of Thomas Cullinan. The crystal was strikingly clean, there were completely no cracks, inclusions and bubbles in it. The only defect of the diamond was the presence of a black spot in the center of the stone. The diamond color game was gorgeous. It varied depending on the angle of incidence of light, which indicated the presence of internal stress in the crystal, which is not uncommon for large-sized diamonds. However, due to the presence of stresses, there was a high probability of cracking. That is, the stone was heterogeneous, which excluded its faceting in its original form. Diamond Cullinan before processing Many wanted to see the largest diamond, but for a long time there were no people willing to buy a stone, due to its high cost. The rulers of the Transvaal Republic acquired a stone after the end of the war in 1907. The stone was a birthday present for the English king Edward VII. The nine largest parts of the Cullinan diamond after separation Initially, the ruler of England did not appreciate the gem. In 1908, the king ordered to split the mineral into several parts and cut it. Famous Asskar brothers - jewelers from Amsterdam studied the structure of a crystal for about half a year, choosing the most suitable place for a strike, in order to split the diamond into several parts. A half-inch long incision was made in the gem, into which a knife made especially for this was placed. One bounce cracked a diamond at its defective points. Glass copies of nine Cullinan diamonds after separation After four years, 2 large, seven 7 medium and about 96 small diamonds were made, the purity of which hit. Below we consider the largest and most famous of them. “ Cullinan 1 ” is a colorless transparent drop-shaped stone with a weight of 530.2 carats. Diamond has 74 facets. "Big Star of Africa" ​​adorns the rod of King Edward VII. It is the largest processed diamond in the world. Can be removed and used as a brooch. Storage - London Tower. “ Cullinan 2 ” is a large diamond having a mass of 317.4 carats. "The Second Star of Africa" ​​adorns the crown of the British Empire. Next to this gem is a ruby ​​"Black Prince". The crown is kept in the Tower of London. This crystal can also be taken out and used as a brooch, along with “Cullinan-I”. “ Cullinan 3 ” and “ Cullinan 4 ” are pear-shaped (94.4 carats) and square (63.6 carats) diamonds. The latter could be inserted into the crown of Mary, the wife of King George V. Queen Mary often wore a brooch from the Small Stars of Africa for important events, such as meetings and weddings. “ Cullinan 5 ” is a heart shaped ornament weighing 18.8 carats. In 1910, the ruling leadership of South Africa presented an unusual cut and shape stone as a gift to Queen Mary. The gem was made as a brooch with a frame of platinum and diamonds. The Heart Brooch was used as a removable center for a belt made for Delhi Durbar in 1911. Mineral " Cullinan 6 " - "King of Stones", having a cut "Marquis", weighing 8.8 carats. In 1907, the stone was a gift to Queen Alexandra from her husband, King Edward VII. Later, after the death of her husband, Alexandra handed over the diamond to the throne to Queen Mary. Soon, she decided to transform Delhi Durbar's Necklace, adding gem to it as a removable diamond-encrusted pendant. “ Cullinan 7 ” together with “ Cullinan 8 ” today is an integral piece of jewelry. “Cullinan VII” - a 11.5 carat gemstone with a “Marquis” cut - a pendant bought by Edward VII from Asher. His wife, Queen Alexandra, placed her on her royal crown. Today, the pendant, coupled with “Cullinan VIII”, an emerald cut crystal, weighing 6.8 carats, make up a solid brooch. "Cullinan 8" was donated to the English Queen Maria by the authorities of South Africa in 1910. The diamond "Cullinan VIII" was also used in the corsage prepared for Delhi Durbar. The Cullinan 9 gem is a 4.4 carat diamond that adorns the ring.

5-Diamond The Promise of Lesotho:

The White Diamond, dubbed the “Promise of Lesotho”, was found in 2006 in the Letsing mine of the South African Kingdom of Lesotho. With a size of 603 carats (121 g), he was not included in the list of the 10 largest diamonds in the world, but at that time headed the 15th position in the gemstones rating in terms of size, was recognized as one of the wonders created by nature. After research, the diamond “The Promise of Lesotho” was assigned a class D - the purest diamond. Since then, it began its history and travel across the European continent. After a month and a half, the diamond was delivered to Belgium, where it was sold at an auction in Antwerp for $ 12.4 million to Lawrence Graff, the owner of the British company Graff Diamonds. Lawrence Graff recruited about 35 specialists to make several large cut diamonds from a large raw stone. Thanks to their painstaking efforts over the course of 5 months, the largest of 224 carat transparent jewels found a pear shape and became the “heart” of a beautiful necklace of 26 stones (all the stones of the necklace are parts of a diamond, the Promise of Lesotho). All components of the product were polished and acquired an impeccable look. Each diamond has a laser engraving with the graff inscription: however, it can only be seen at a tenfold magnification. The total cost of the decoration is 50 million dollars. Potential buyers crave to seize diamonds separately. But all applications Lawrence Graff answers the same thing: "The necklace can be sold only in full."

6-Orlov Diamond:

"Orlov" (or "Lazarev" or "Amsterdam") is the largest of the seven famous gems in the Diamond Fund of the Russian Federation. This stone is an ornament of the Imperial scepter of Catherine the Great since 1784. The diamond "Orlov" is related to the equally well-known diamond "Shah" , as they were found in one place. Stone found in India at the beginning of the 17th century. At that time it was a piece of 300 carats, most likely separated from an even larger diamond, which had the shape of a dodecahedron. Gem is about two-thirds of the main diamond, which was supposed to weigh about 450 carats. Transparent and pure diamond has a nice blue-green tint. The base of the gem is not a very smooth cleaved surface. The shape of the stone resembles a chicken egg, divided across. The stone cut is a form of Indian rose and has a large number of small faces, which are arranged in tiers. The stone has retained the original cut, so it is of immense historical interest. The first owner of the gem was a descendant of the great Mongol dynasty - Shah Cihan. A solid stone was sent to the jewelry workshop for artistic cutting. According to the legend, Shah was extremely upset that the weight of the stone had greatly decreased, and Cihan not only did not pay the master for the work, but also confiscated all the jeweler’s property for “spoiling” the gem. According to legend, “Orlov” is one of the diamonds, paired with “ Koch-i-Nor ”, which served as the eyes of the statue of Brahma. The statue stood in a temple in southern India. The gem stole from a Hindu temple a French soldier who managed to ingratiate himself with the priest of the temple. And one evening, because of the raging storm, there was no one left in the temple except for a stranger. Taking advantage of the opportunity, the Frenchman takes out a diamond from the statue's eye. The temple had a lot of jewels and besides the stone, but the thief did not have enough restraint and calm. Taking only a diamond, he embarks on flight, fearing that the servants of the temple will return. The Frenchman sells the gem to the captain of an English ship for a ridiculous price, and he resold it to a Jewish trader in London. But is the legend right? The early history of the stone is little known to us. The reliable fact of history is that Prince GG Orlov, a former favorite of Catherine the Great, in Amsterdam, bought this stone from the Armenian merchant Lazarev (hence the second name of the stone). Orlov knew that the ruler loved diamonds and even preferred to play cards on stones, not on money. With this gift he hoped to return to the Empress's favorites. Catherine II received a generous gift, but Orlov remained the former. Catherine named the stone after the donor and ordered her to be inserted into the upper part of the Russian scepter. Today, the Orlov diamond is the largest stone in the Diamond Fund of the Russian Federation.

7-President Vargas Diamond:

In 1938, a huge crystal was accidentally discovered near the Santo Antonio River in Brazil. It was a transparent diamond weighing 726.6 carats.Flat in shape, on two edges with a pale yellow color, a large cleavage surface and two distinct faces of a rhombododecahedron. The stone was named after the country's president, Hethulio Dornelles Vargas. There are two stories about the founders who were lucky to bring the stone into the eyes. The first one says: these were workers who worked near the river. The other is that two farmers, wandering along the bed of a dried-up reservoir, noticed a stone glistening in the rays of the sun. After going through a lot of hands, in 1939, the diamond acquired Harry Winston. The price was 600,000 dollars. 29 diamonds were made of stone. The largest was a mass of 48.26 carats; it was called the diamond President Vargas. 14 large stones gave emerald faceting, 10 medium - triangular. From 1944 to 1958, the diamond was with the wife of Robert Windorf. Then he again came to Harry Winston. In 1961, the stone was transferred to an unknown owner. A diamond of 28.03 carats in 1989 at Sotheby's auction cost 781 thousand dollars. A crystal of 25.4 carats in 1992 at the same auction - 396 thousand dollars. The 27.33 carats stone is from Robert Muawad, an Arab collector.

8-Regent Diamond:

In antiquity, diamonds were said to be the light of the sun, condensed in the earth and cooled by time. Behind the famous stones, the train of mysterious stories always stretched, giving them even greater uniqueness and often raising their price considerably.Stones weighing more than 100 carats are considered unique. Of course, after the discovery of a diamond of 1,100 carats in November 2015 at the mines of Botswana, which was considered one of the largest Regent's diamond, it no longer seems so significant, because it weighed only 400 carat. Later, a diamond, cut to 140 carats, served as an ornament to a collection of jewelry belonging to French monarchs. His story of the rise to the heights of royal power began on the famous Indian mines in Golconda in 1701. The Hindu, who found a huge diamond, wanted to get his freedom with his help. According to legend, he hid it in his wound under a bandage and gave the stone to the captain of the ship. The story then claims that the slave was killed and thrown overboard, and the stone fell into the hands of the then governor of Fort St. George in Madras, a certain Pitt, after whom he received his first name. Further contradictory information agrees that after returning to Britain, Pitt found a jeweler who agreed to cut the diamond, which cost the former governor about 5,000 thousand pounds sterling, and the jeweler 2 years of hard work. In 1717, the diamond was acquired by the then regent of the minor king Louis XV, Duke Philip of Orleans. It was in his honor, the stone was given a different name, which eventually stuck with it in history. In the years of the French Revolution, after the execution of Louis XVI, the diamond was stolen during the Republican revision. But a year later, he unexpectedly found himself again among the treasures of now Republican France. He was sold to the Russian merchant Treskov in order to equip the troops of the French army with the proceeds. Diamond Regent. Illustration from the encyclopedia "Nordisk familjebok" Then the Regent's diamond returned to France again. This time its owner was Napoleon Bonaparte, who decorated him with the hilt of the sword that was on him during the coronation. After his abdication, the diamond traveled for some time around the courtyards of European monarchs and again found itself in Paris as a gift from the Hapsburgs to Napoleon III. The diamond was set in the diadem of his wife - Empress Eugenia. The sparkling snow-white handsome with a barely noticeable bluish tint, since 1886 the Regent's diamond, as the historical heritage of France, forms part of the exposition of the museum heritage of the Louvre.

9-River Oye Diamond:

The “Uoe River” is a diamond that is among the ten most important in the world. According to the latest data, he is in ninth place, behind “Cullinan”, “Excelsior”, “Star of Sierra Leone”, “Great Mogul”, and Botswana with a weight of 1111 carats, found in the fall of 2015. The diamond “River Uoye” was discovered in West Africa in early 1945. He was found at the reservoir of the same name near the town of Sefadu in Sierra Leone. The stone was diamond shaped. The weight of a unique find is 770 carats. He received another name - "The Diamond of Victory", he was given in honor of the defeat of the Nazis in the same year. From the “Diamond of Victory” turned out 30 diamonds. The largest of them was a stone weighing 31.35 carats. The fate of precious products is still unknown. The owners keep the secret, so now nobody knows what they looked like. Their descriptions and photographs are not even in specialized jewelry editions.


10- The Shah Diamond:


The story of the famous stone Diamond "Shah" is of Indian origin. In Russia, this stone appeared in 1829, when, as a result of the massacre in Tehran, the Russian embassy was killed, headed by A.S. Griboedov. This stone received its name only on arrival in Russia: it did not have a proper name in Persia. The stone is not faceted, the edges are merely polished: a part of the natural faces of the octahedron has been preserved on it. The Shah diamond has an elongated shape, and a ring-shaped groove indicates that it was worn as a talisman. On three well-polished diamond planes inscriptions were inscribed: the names of the three rulers of Persia. Currently, the stone has a weight of 88.7 carats, but it is believed that before processing it weighed about 95. The mineralogist and geochemist AE Fersman who studied the stone in 1922 noted the perfect transparency of the stone. Diamond "Shah" has a yellowish color with brown patches. The beginning of the history of this gem dates back to the 16th century. Diamond was found on the banks of the river Krishna, in the mines of Golkonda (India, shortly before they were completely abandoned. By 1591, the diamond belonged to the ruler of one of the Muslim states in India - Burkhan II. A large transparent stone struck the imagination of the ruler, it was he who ordered the first inscription engraved on the diamond, calling itself the "Lord of Order." We know that diamond is the hardest stone, it is extremely difficult to even scratch it. Today, in addition to mechanical grinding (when diamond is polished with diamond), three more processing methods are used: an electric spark, a laser beam, and chemical etching. One can only wonder at the master's patience, who managed to cut out the inscription on such stubborn material, given the primitiveness of the tools of the day. But the diamond was not long in the treasury of Burkhan: in 1592, Shah Akbar, who conquered this state, appropriated a stone. Thus, a large diamond became the regalia of the Great Mongols. For about forty years, the stone was in the treasury, until it was noticed by Akbar's grandson - Shah Jihan, who exalted the Mongolian state even more. Having settled with all the claimants to the throne, Cihan began to rule. This ruler led a controversial policy: simultaneously with a twofold increase in taxes, Cihan built irrigation canals in certain parts of the state. The life of this ruler was decorated with love for a single woman - the beautiful Mumtaz Mahal. The emergence of the Taj Mahal - one of the wonders of the world - we owe it to Shah Jihan: after the death of his wife, he ordered the best masters to build a mausoleum, which is not equal in the whole universe. It is curious that this ruler combined government affairs with the faceter's craft — he spent a lot of time in his workshop, devoting time to processing the gems. Cihan gave the order to cut the second one on the stone: his name and the dates of his reign. At this time, the unknown master used all the properties of the graphics of the language: now the inscription looked like an ornate, whimsical pattern, and not like ordinary text. Tavernier, we know that the throne of the Persian rulers was endowed with a canopy, richly decorated with various precious stones. Diamond “Shah” was hung on this canopy so as to be constantly in sight of the ruler. The third inscription on the stone ordered Fatah Ali Shah to be made in 1827, in honor of the thirty-year anniversary of his reign. Writing on the last free face of diamond amazes with talent, perfection of work and intricate fantasy. After victory in the Russian-Persian war, Russia sent ambassadors to Tehran led by A.S. Griboyedov to sign a peaceful conversation. After the massacre of the Russian ambassadors, the ambassadors of Persia went to Nicholas I. The price of spilled blood was a diamond, which received the name "Shah" in Russia. Due to this stone, the death of the great writer and the last two kururs were forgiven - about 4 million rubles. Before the October Revolution, the diamond "Shah" was kept in the treasury of the Winter Palace, after the revolution the stone was transported to the Kremlin. Today this stone belongs to the diamond fund of the Russian Federation.
