On February 15, 2006, Christie's in Geneva auctioned a 8.62-carat Burmese ruby ​​for $3.44 million, or 25 million yuan. This ruby ​​is called "Graf Ruby". In 2014, this Burmese ruby ​​returned to the auction. This time, it shot a price of 60 million. In just eight years, its value has soared by 35 million. In addition to the "Grav Ruby", most of the rubies that have recently appeared on the auction floor, with a carat price of more than 50,000 US dollars, are mostly produced from the Valley. Ruby shoes with 4,600 rubies made by HARRY WINSTON Why are Burmese rubies so popular? Quality guaranteed When we talk about the quality of ruby, then we must avoid the color, clarity and carat number. colour Color is one of the most important factors in evaluating the quality of rubies. We know that the type and mass fraction of trace elements in ruby ​​is the main factor in their coloration. The trace elements in ruby ​​have a certain relationship with the surrounding rock. [Grinded ruby] polished ruby According to the different types of ruby ​​surrounding rock, ruby ​​can be roughly divided into three types: (1) Marble type ruby. This type of ruby ​​usually has a low Fe content and a strong fluorescence, and most of the Burmese and Mongolian rubies belong to this type; (2) Basalt type ruby. This type of ruby ​​contains high Fe content and weak fluorescence, and Thai and Cambodian rubies belong to this category; (3) Gneiss type ruby. This type of ruby ​​contains Fe content between marble type ruby ​​and basalt type ruby. So we can know that the Burmese Ruby Ruby is pure in color, bright in color and high in saturation. And because the content of iron in the ruby ​​ruby ​​that can suppress the fluorescence effect is very low, the top-level ruby ​​ruby ​​has a pure red fluorescence. This makes the Burmese ruby ​​look brighter in the sun and more vibrant than the rubies of other places. Secondly, the ruby ​​inside the Mogok in Myanmar contains a large number of acicular rutile inclusions. The internal reflection effect of the densely distributed rutile inclusions makes the ruby ​​color of the Mogok in Myanmar more uniform and soft. This is not what other regions of ruby ​​do not have. For another high-quality ruby ​​origin in Thailand, due to its high iron content, it is dark in color and mostly dark red or brownish red. This makes it look like no Burmese rubies. In addition, the Thai ruby ​​has no star ruby ​​because it lacks rutile inclusions. Carat number As the saying goes, things are rare. Due to long-term mining, the ruby ​​resources of the Mugu mine in Myanmar are on the verge of exhaustion. In the international market, more than 5ct of the ruby ​​ruby ​​has been very rare, more than 10ct can be regarded as a rare treasure. In contrast to the rubies in Mozambique, the ruby ​​of the Grand Carat is rare, but it still has a stable output. It is because of the rareness of the Dakla Mogu Ruby that it has frequently sold high prices on international auction sites. Cleaness In terms of clarity, the Myanmar ruby ​​can be a little flattering. The long-running saying of “ten red and nine cracks†in the market means that the cracks in most Burmese rubies are very developed. Therefore, most Burmese rubies are heat treated to improve clarity. This also makes the natural, non-burning transparent Burmese Mogok ruby ​​more precious. The strong competitor of the Myanmar ruby ​​Mozambique ruby ​​is more exciting in terms of clarity. Extremely high visibility The Mugu Valley mining area in Myanmar has a long history. Since the 15th century, Myanmar has continued to provide high quality rubies. Therefore, many famous rubies in history have been produced in the Mugu mine area in Myanmar. These “stars†are often embedded in royal jewellery and hidden in museums. With the popularization of auction houses in recent years, the concept of inheritance has been promoted at the auction, while the concept of inheritance of the royal family, celebrities and movie stars has been popularized. This has made the Mugu mine in Myanmar more widely known.

The "sunrise" ruby ​​that currently maintains the highest record price of ruby ​​comes from the Mugu Valley in Myanmar. It was evaluated by Knight, the director of Sotheby's (International Weibo) International Jewelry Department. "Reviewing the past 40 years, this is the only one I have ever seen, and the ruby ​​with such a special color can no longer use 'rare' To describe it." The "pigeon red", considered to represent the highest quality ruby, has historically been the proper term for high quality rubies in Meguro, Myanmar. It was not until 2013 that “pigeon red†began to be used to describe rubies from other sources. Compared with other producing areas, new mining areas like Tanzania and Mozambique do not have enough historical precipitation; the ruby ​​producing areas like the famous ruby ​​producing areas like Thailand and India are not as good as the ruby ​​rubies. Extremely expensive As everyone knows, gem resources are a non-renewable resource. After a long period of mining, the ruby ​​resources of Mogok in Myanmar are now on the verge of exhaustion. There are fewer and fewer high quality rubies that can be mined. Before 1962, the ruby ​​industry in Myanmar was very developed. However, the coup in Myanmar in 1962 caused all the mining areas in Myanmar to be nationalized. For a long time, only a very small amount of Burmese ruby ​​ruby ​​was circulated on the international market, and recently Myanmar has frequently closed mines. Perhaps in the near future, it is difficult to see Myanmar rubies again in the market. Although the Mugu Valley ruby ​​is highly sought after at the auction, when we buy rubies from ordinary people, we don't have to over-purchase the origin of rubies. "Heroes don't ask for the source", good gems don't have to pursue too much. Even a high-quality mining area such as Meguro in Myanmar will produce a rare ruby, so learning to identify the quality of ruby ​​is the most important.
