Until the1870s, due to the poor mining conditions, the king began to negotiate with external companies to mine the mine. He finally gave the mining right of the mine to Mumbai Trading Company, but in 1882, they cancelled the mining right of Ruby. This behavior, as well as other provocative actions against the timber industry controlled by the British government, led Britain to send 30,000 troops to Myanmar territory in 1886 to control various resources in Myanmar. In the same year, Britain annexed the Indian colony in northern Myanmar. 1887 10, the regulations on ruby in upper Burma were promulgated, and the so-called "stone zone" clause was created. In June165438+1October of the same year, Mogolz Stone Road was officially promulgated. From 65438 to 0889, the British government, through the Indian Minister of State, handed over the control of the Gu Mo mining area to Edwin Streeter, a jeweler in Bond Street, London, and established the Myanmar Ruby Mining Company in Myanmar.
When Myanmar Ruby Mining Company entered Gu Mo, they began to face a series of problems, the most important of which was that they found that the richest ruby mining area was actually located in a small town below Gu Mo mining area. Before mining, they had to move the whole town to mine rubies. In the following years, the British built roads, bridges, buildings, five mine washing plants and hydropower stations here. In addition, the company also faces the problem of high-quality and large proportion ruby minerals smuggled by miners. In order to protect local miners, Life Myanmar Ruby Mining Company shall not disturb existing miners at work or dismiss them without reason. However, as a British company with the monopoly right of Mughal stone mining area. Ruby mining area in Gu Mo mining area was very prosperous at that time, and five concentration plants handled thousands of tons of ore every day. With the increasing prosperity of this area, large and small mines have been established in the vicinity of Gu Mo 12 km. All mining areas are open-pit mining, and large-scale hydraulic monitoring or "cannon" high pressure is used to clean gems and ores.
It was not until 1908 that a large number of synthetic rubies entered the global market that the region was controlled by Myanmar Ruby Mining Company. However, with the entry of synthetic rubies, global ruby traders are in a panic, and the sales of natural rubies are also greatly reduced.
Although the mining of Gu Mo mining area was going on during World War I, the ruby mining industry in Myanmar began to enter the asset liquidation in 1925. At that time, the company still had control over the mining area for six years, but it struggled until 193 1 year to return the control to the government. Keely is the manager of a mining company, and he has a profound insight into modern ruby mining in Gu Mo. He pointed out that several heavy rains in 1929 caused frequent floods, destroyed all electric pumps and flooded all drainage channels in the mining area. The great lakes caused by floods still exist today. People have tried many times to repair the flood disaster, but they have never succeeded.
Later, because the cost of modern mechanical mining reduced the economic benefits, local miners and their century-old mining methods regained control of the Mogol area again. All restrictions on leasing have been lifted, and the government only charges each miner a monthly mining license fee of 10. Except during World War II, that is, from May 1942 to April 1945, during the Japanese occupation of Myanmar and the subsequent US-Japan war, the local mining industry maintained active mining at other times. 1963, when the Burmese government nationalized all industries in the country, it also banned all private enterprises, including mining and selling precious stones. Nowadays, the declining gem mining industry is controlled by the army, and all gems can only be sold at the annual auction held by the mining development company in Yangon, but these auctions are not very successful because most gems are of poor quality. In 1969, * * sold $2.4 million in the fifth auction, but jumped to $5.8 million in 1973. At present, the Myanmar government has completely banned the opening of the ancient animal husbandry mining area to foreigners, and only provided limited special entry permits to Myanmar nationals. The area is also surrounded by Burmese government forces and large minefields laid by them.
Military rule, harsh natural conditions, limited technical application and political blockade have led to a large number of high-quality Burmese rubies circulating in the market. Since the beginning of the last century, Burmese rubies in trade may have passed through several generations, and the huge demand for high-quality Burmese pigeon blood red in the market has made many previous Burmese rubies undergo heat treatment to obtain better appearance, and high-quality Burmese rubies that have not been fired are rare. Multiple conditions determine the high value of Burmese ruby and its unique origin significance ~
