Rubin Alan Kaplan or Ruby Mogok

RubinAlan Kaplan, also known as Rubin Mogok in the world, was named after Alan Kaplan, a famous geologist in mineralogy, as well as a gemstone dealer. Alan Kaplan purchased a ruby ​​gem during a trip to Burma, in the 1960s or the 1970s. Rubin remained in the Kaplan collection until 1988, and after that he was put up for auction at Sotheby's in New York, where he beat all prices, and fixed the record for the hype.

The second name of the ruby ​​"Mogok" comes from the source of the best quality rubies all over the world, the Mogok mine in Burma.

The characteristic of the gemstone: Rubin Alan Kaplan is one of the best rubies in the world

Rubin Alan Kaplan weighs 15.97 carats, he is decorated with a perfect cut pillow. The pigeon's blood is rich in red, and clarity is excellent transparency. The quality of the ruby ​​is so perfect that it reached the highest price per carat of ruby ​​at auction in the 1988th year, and this price only increased until the year 2006.

Burma rubies and ultraviolet lighting

Burmese rubies of intense red color, become even brighter, almost glowing from the inside, with ultraviolet light, as well as with warm red. They are exposed to natural sunlight rich in ultraviolet rays, and shine. The presence of such an effect in ruby ​​may indicate the origin of the gemstone. The rubies mined in Thailand have less fluorescence in the ultraviolet, and the rubies from Sri Lanka become orange-red.

Causes of red rubies

Alan KaplanThe cause of red in rubies is chromium, which displaces certain aluminum atoms from the alumina crystal lattice, which constitutes corundum. The rubies in Burma and Sri Lanka contain only chromium as an agent affecting the color of the gemstone. Thailand rubies contain iron, in addition to chromium. Iron gives a deep red color to ruby, with brown or purple tones.

How to determine the ruby?

To distinguish the ruby ​​from the pomegranate and red spinel, you need to see how the light passes through it. Dichroism is peculiar to rubies, when one ray enters the gem and several leaves.

Rubies crystallize into trigonal or hexagonal crystal systems. When considering crystals in hexagonal syngony, strong dichroism is observed, two colors appear: purple-red and red with a light orange shade. Red garnet and red spinel crystallize in a cubic system, and dichroism is not inherent in these stones. This is how it is possible to distinguish a ruby ​​from other twin-stones and fake stones.

Ruby's story Alan Kaplan

Alan Kaplan bought the ruby ​​presumably in the 1960s and 1970s, during one of his trips to Burma. Most likely, the ruby ​​originated in the Mogok deposit, the world's most important source of rubies since the 15th century. The Mogok field is located about 650 kilometers north of the capital city of Rangoon, Japan, and about 100 kilometers northeast of the second largest city in Burma, Mandalay. The city of Mogok is located in the Katha region, this is upper Burma, at an altitude of 1,500 meters above sea level. The city is surrounded by hills, rising to a height of 2,300 to 2,400 meters above sea level. The area where the ruby ​​mines are located is only about 112 square kilometers.

The hills surrounding Mogok were formed as a result of the collision of the Indian subcontinent of the continental tectonic plate with the tectonic plate of Eurasia that occurred about 40-60 million years ago. The energy released during tectonic activity helped transform corundum, which contains igneous rocks, into metamorphic rocks. Crystalline limestones such as marble are mainly obtained from metamorphic rocks. But due to the fact that erosion lasted for millions of years, rubies were formed, descending down the hills, into the valley, where the modern deposits turned out to be.

Legend has it that rubies were first discovered by bandits in Mogok in the 15th century. The robbers settled there after the expulsion of the kingdom of Mandalay. For more than six hundred years, the deposit was plundered, having practically exhausted its reserves of rubies. Several new deposits of rubies were discovered there recently. One of these deposits is Mong Hsu, discovered in 1992-1993. The Mong Hsu rubies deposit is located approximately 60 kilometers southeast of Mogok. But the rubies mined in this field do not have a sufficiently good red color, and require heat treatment so that their color still plays.

KaplanAlan Kaplan - a dealer for gems and minerals

Alan Kaplan, presumably of Jewish origin, was born in New York or New Jersey on December 29, 1913. Already in childhood, he liked the natural sciences, interest in minerals appeared later - in high school. After the high school was over, in 1933, Alan Kaplan worked at the Museum of Natural Sciences in Denver, but he did not work there for long. He then began collecting fossils and minerals in the Colorado region. What he found, sold for small ads in journals on mineralogy.

Alan Kaplan completed a three-year course in geology and mineralogy in the years 1934-1937, at the University of Colorado. He then went to graduate school at a school in the state of Colorado, until 1938. Immediately after that, Alan Kaplan began to build his career as a collector of various minerals and a dealer.

A little later, he decided that it would be good to go on a trip to Brazil, to hunt for minerals. This trip was a success. Before World War II, Alan Kaplan managed to make ten trips to Brazil. He has become one of the most successful mineral dealers in his country. This man supplied minerals for places like the Smithsonian Institution, the American Museum of Natural History and Harvard.

Alan KaplanAfter recruiting during the Second World War in 1943, he served in Italy, where he stayed until 1945. At the end of the war, Alan Kaplan once again became a mineral hunter in Brazil. He visited this country 12 more times at least. At the end of 1958, the interests of Alan Kaplan changed dramatically, and instead of minerals, precious stones came out on top of his interests.

Alan Kaplan in search of precious stones makes several trips to Colombia, to purchase emeralds. He also travels to Burma, just for rubies. It was during one of these trips to Burma that Alan Kaplan bought a ruby ​​in his own name — an unprocessed ruby. Alan Kaplan has become one of the most famous and successful dealers in New York, a pearl dealer. He is credited with the acquisition of the world's largest emerald Mogul, as well as the ruby ​​Mogul. Alan Kaplan died in 1998, when he was 85 years old.

Rubin Alan Kaplan at Sotheby's auction in New York 1988th year

After the ruby ​​was bought in Burma, Alan entrusted his cutting and polishing to an expert working for his company. Under the leadership of Alan, a successful cut was carried out, and it turned out that with the ideal shape, the ruby ​​became the most expensive ruby ​​in the world.

In October 1988, Alan Kaplan’s ruby ​​was auctioned off at Sotheby’s in New York. After the bidding, Ruby acquired the company of British millionaire Laurence Graff for 3,630,000 million US dollars. Rubin bought at a price of 227 301 thousand American dollars per carat. At that time, it was the highest price ever paid for one carat of a ruby.

Laurens Graff installed the ruby ​​in a wedding ring, after which he sold this ring to the Sultan of Bunei, for one of his wives. By the way, Laurens Graff was the main supplier not only of diamonds, but also of other precious stones and jewelry to Sultan Bunei (Bunei), one of the wealthiest people in the world. It is to him Laurens Graff owes his condition and success.

Rubin Alan Kaplan Lost Price Leadership

After 17 years, Ruby Alan Kaplan lost his lead in price. On April 12, in 2005, a ruble weighing 8.01 carats was sold in New York for 2,200 million US dollars. The sale took place at Christie's auction in New York. It turns out that the price per carat of a new ruby ​​was 274,656 thousand American dollars, which was more than the price per carat of ruby ​​Alan Kaplan.

Another price tag per carat ruby

But the price per carat of ruby ​​did not stop there, and already on February 15, 2006, another ruby ​​installed in the Bulgari ring (Bulgari) was sold for 3,637,480 million US dollars. The sale took place at Christie's auction. Thus, the price per carat of ruby ​​amounted to 421,981 thousand US dollars. Ring Bulgari again acquired Laurens Graff, and may have resold it to the Sultan of Brunei, which he often dealt with.
