South Asia and South America and Africa are the main producing areas of colored gemstones, especially in Myanmar, Brazil, Sri Lanka, Madagascar, Russia and other countries. The top minerals with several kinds of gemstones are really enviable. Let us understand the geography of these areas. Humanity. Myanmar: Geological activities include “Royal Blue†and “Pigeon Blood Red†Located in Southeast Asia, Myanmar is located at the collision boundary between the Asia-Europe plate and the Indian Ocean plate. The intense geological activities from ancient times have created Myanmar's status as a global jewellery producer today. The royal blue in the top quality of sapphire, the top quality of ruby - Pigeonblood, all produced in this country, so the national stone of Myanmar is also set to ruby. In addition, high-quality spinel, tourmaline and olivine are also produced in Myanmar. Since Myanmar was a Chinese genus in the Ming and Qing Dynasties, it often tributes high-quality gemstones to China's princes and nobles. At present, most of the jewelry materials collected in the Palace Museum of China are sourced from the country. Myanmar is a multi-ethnic country. The armed forces of government forces and ethnic minorities often have conflicts. At the same time, Myanmar is located in the Golden Triangle. There are a large number of people engaged in drug cultivation and trafficking. Therefore, there are often local armed forces and black and evil forces. If you want to enter The gem mining areas controlled by these armed forces are inevitably insufficient to buy insurance. Brazil: the world's largest producer of gemstones Brazil is the world's largest producer of gemstones, with color gemstone production accounting for around 65% of world production. The gemstones produced are large and of high quality, such as amethyst, citrine, tourmaline, topaz, aquamarine, emerald, etc. The country also produces a mysterious Paraiba tourmaline with electric light. The color is fascinating, the price per karat can reach tens of thousands of dollars, still far from meeting the market demand. Brazil's gem processing industry is also very developed. In the southeast of the capital Brasilia, there is a small town called Cristina. There are more than 100 gem shops and jewels and workshops in the city. Gems are designed, cut and inlaid. Locally, at a low price, 70% of the gems in Brazil "flow" from Christina to the world. Sri Lanka: "Gem Island" in the shape of a pendant Sri Lanka is rich in gems and is famous in the world! If you are interested in looking at the outline of the country on the map, would you think it is like a pear-shaped cut gemstone pendant? The gems produced in Sri Lanka are: sapphire, ruby, gold emerald, moonstone, sea sapphire, garnet, etc. Almost all the high and middle grade colored gemstones are produced in Sri Lanka, and the quality is very good, so it is Known as the "Gem Island". Sri Lanka has a wealth of gem resources, which is related to its special stratum structure. In addition to the gem mines in the Jaffna peninsula in the north, Sri Lanka has a rich gemstone resource in the mountains, river valleys, plains and hills all over the country. Due to the abundant underground gemstones, the Sri Lankan government has enacted various regulations on gem mining in order to prevent indiscriminate mining. No one can dig a pit to mine a gemstone. It is necessary to dig before applying to the relevant department for a permit. Otherwise, it is considered illegal to excavate the gemstone and is subject to punishment. In Sri Lanka, there are countless myths and legends about gems. People are also very religious about gems. The number of people engaged in the jewelry industry is about one-tenth of the country's total population. However, due to the frequent armed conflicts between the Sri Lankan government forces and the anti-government armed forces, the Liberation Tigers of Tamil Eelam, it is not easy to go to Sri Lanka to obtain gemstones. Madagascar: the world's most complete range of gemstones Located in the South Indian Ocean, Madagascar is rich in flora and fauna and beautiful natural scenery. It faces the southeastern part of the African continent across the sea. It is nine times the size of the island of Sri Lanka and the fourth largest island in the world. According to the theory of continental drift, in the ancient times, the two islands of Madagascar and Sri Lanka were connected and belonged to the ancient continent of Gondwana. The geological ages and characteristics are also very close, which may be why both islands are rich in high-quality gemstones. s reason. Almost all of the colored gemstones found on Madagascar have at least 30 varieties on the market: emeralds, rubies, sapphires, gold emeralds, aquamarine, beryl, beryl, and various tourmalines. Quartz gemstones, garnet gemstones, feldspar gemstones, apatite, cordierite, vermiculite, topaz, zircon, opal, etc... Although many mining areas are found late, Madagascar is becoming an emerging But the important gemstone origin. Colombia: synonymous with top emeralds Colombia is synonymous with top emeralds. The emeralds produced in the area are rich in color, producing tens of millions of dollars of emeralds every year to the world's markets, accounting for half of the global emerald market. But unfortunately, the civil strife in Colombia has lasted for several decades. The anti-government guerrillas are arguing against one another, confronting the government, and a large number of paramilitary organizations, which also constitute a social unrest. What is even more frightening is that drug trafficking activities in Colombia are rampant. The activities of drug-trafficking groups are all over the country. Terrorist activities such as car bombings and assassinations of the government have occurred from time to time, and they have basically appeared in remote areas that are difficult to control by government forces, such as mining areas. If you want to enter the mining area, it is recommended that you bring your friends to the helicopter. The environment of the Columbia Emerald Mine is usually shrub, the road is rugged, and a large bulldozer can be seen in the mining area. With a huge and powerful grab, the mud on the mountain side is excavated to find out if there is any treasure left. In the mining area, gunmen and greedy workers can be seen everywhere. They know that you want to buy emeralds in the mining area, so you must carry large amounts of cash, and when you leave, you must have beautiful emeralds, so, greed For most people, most people in the mining area are fat sheep. A high-quality emerald, from the buried land to your hands, how many dangers have passed in the middle, only jewelers can know. Tanzania: Tanzanite, the world's only source of origin 1000 times less than diamonds The foothills of Mount Kilimanjaro in northeastern Tanzania, East Africa, is the only global source of tanzanite, adjacent to the Kenyan border. The deposit is exposed in the northwestern foothills of the Llatema Mountains, near the town of Merelani. The deposit is formed in rock formations in the region with a geological age of 1.1 billion to 1.5 billion years ago. These rock formations are part of the Mozambique geological belt and have experienced extreme high temperature and high pressure geological environments. The tanzanite veins are exposed from the shallow area of ​​the A area, extending along the B, C, and D areas to the depth of the rock formation. The D veins reach the best depth for producing high-quality, high-quality tanzanite, and the depth of production reaches the surface of the D area. The velvet color and the collection of tanzanite produced by the deep quality veins below 800 meters are called BLOCK-D stunning treasures. Russia: the most valuable metamorphic origin in history The Ural mining area in Russia is the most famous producing area for the world's metamorphic rocks. In the 19th century, the Finnish mineralogist N. Nordenshild first discovered a metamorphic stone in the emerald deposit. This gem is brilliance, but the clarity is very rare. The deposit is located in a structural bond zone in the northern uplift of the Eastern Ural. In the mica quartzite produced in ultrabasic rocks, the surrounding rocks are metamorphic ultrabasic rocks, including granite and fine-grained rocks. The gold emerald is porphyry in the mica rock, accompanied by emeralds, apatite and phlogopite. The gold emerald here is mainly a stone, with a small particle size. The texture is transparent, the color is blue-green in daylight, unlike the color of the jewels of Sri Lanka, it is yellow-green. Russia has a vast territory with a variety of colored gemstone deposits, but it has not been as prosperous as the propaganda of the former Soviet Union, nor is it comparable to the country's diamond wealth. Russia began to exploit its gemstone wealth as early as the mid-17th century. Malachite was discovered in the Ural Mountains in 1635, and amethyst, beryl, colorless crystals and topaz were discovered in 1668. Deposits such as agate, carnelian, chalcedony and jasper were found along some rivers in eastern Siberia. Between 1840 and 1900, Russia was the main source of metamorphic rocks. During this period, the Takovaya area on the eastern side of the Central Ural is rich in large-grained emeralds and metamorphosits. Although there is no detailed output news, it is speculated that the deposit at the turn of the century is almost exhausted. After the Russian Socialist Revolution in 1917, there were no reports of a large number of gemstones in the Ural region. When the Russian gold emerald deposit was considered to be exhausted, interest in color-changing gemstones gradually diminished, as no gemstones with color-changing effects were found in other areas. The marbles produced in Russia are very rare in color and clarity. No matter where they are today, Russian stone is hard to come by. Even if the quality is not considered, the Russian stone is the most valuable in history. If the quality is high and the place of production can be determined, the price will be very high. Afghanistan: World famous lapis lazuli deposit Afghan gemstone resources are very rich, the production area is mainly concentrated in the Pamir Precambrian middle block, from the gemstone genesis analysis can be divided into metamorphic sedimentary type and igneous metamorphic type, metamorphic sedimentary type of main deposits are: ruby, blue crystal Stone, garnet, cordierite, etc., pyrophoric metamorphism mainly forms rubies, sapphires, emeralds, lapis lazuli, etc. In addition, there are some gem deposits related to the meso-Cenozoic pegmatite, such as purple lithium. Pyroxene, tourmaline and emerald, etc., there are many kinds of Afghan gemstones. In addition to the world famous lapis lazuli, gem-quality purple spodumene, ruby, emerald and so on are also high-quality minerals of Afghan gemstones. Due to the unsettled political situation in Afghanistan, detailed investigations and production have not been carried out for many years. Thailand: world-class gem processing plant Thailand is known as the world's colorful gemstone capital, rich in rubies and sapphires. Thailand has geographical advantages adjacent to the world's important colored gemstones such as Myanmar, Sri Lanka and Cambodia. More than 80% of the world's red sapphire is designed and processed in Thailand and sold throughout Thailand. Colored gems are headed by Thailand in terms of quality and variety. Thailand's gem resources are very rich, especially rich in red, blue, emerald and amethyst. The most famous is the precious ruby, the Siamese stone produced by Chanthaburi in eastern Thailand. She has become one of the best gemstones in the world with dazzling color and mysterious atmosphere. China: the world's largest gem consumer market Sapphire is produced in Shandong, China. The sapphire of this property is famous for its large size and crystal integrity. The Altay region of Xinjiang is the region with the richest production of gemstones in China. The highest quality sea sapphire and tourmaline in China are produced here. Topaz, garnet, apatite and golden beryl are produced. It is also the best business in China. Grade emerald origin, but the current production is not large. In addition, Jiangsu Lianyungang is China's crystal town, with a large number of high-quality crystals. In addition, there are also some regions that also produce gemstones, mainly including: 1. United States: The United States is similar to Brazil, mainly producing tourmaline, garnet, peridot, crystal, topaz (topaz) and turquoise, etc. 2. Canada: mainly produces amethyst, tourmaline, nephrite, etc.; 3. India: mainly produces rubies, sapphires, emeralds, dongling stones and garnets; 4. Mexico: mainly produces agate, opal and topaz (topaz); 5, Bolivia: mainly produces crystal gems such as amethyst.
