Shangdong Changle--The largest sapphire mining area in China
As one of the four biggest sapphire mine areas in the world, Changle locates in central Shandong Peninsula, located in north temperate, adequate light rain Heat Over the same period, a pleasant climate, with an area 1,101 square kilometers, a total of 603,000 population. Changle County in the northern part of the county, east of the "World Kite are" Weifang, 150 kilometers away from Qingdao, west of the provincial capital of Jinan 160 kilometers, north of the Bohai Sea and Laizhou Bay 80 km. Changle well-developed transport and Jiaoji Railway, the Jinan-Qingdao Highway, Road and State Highway 309 plastic Wang Road, Tai Yi Road runs through the territory.

Changle sapphire resource-rich, mining area of 450 square kilometers, hundreds of millions of carats of reserves, is the nation's largest World rare one large sapphire mining area, known as "sapphire," and its reputation. Sapphire rely on the rich resources, favourable industrial policy, a good investment environment and constant improvement of the matching services for more than 10 years, Changle and jewellery industry to be rapid development, achieved from scratch, from quantity to quality two major leap national professional jewellery wholesale trading market in China Gem City's growing prosperity, continues to expand the scale and grade, and our gradual development of a larger domestic jewellery distribution centers.

1. sapphire resources

(1) reserves. Tianbao of Changle, and rich in resources. 1800 million years ago, volcanic eruptions, for the people of Changle valuable wealth - Sapphire. 1984, it has been found it. 1986-1990, the department of geological survey in Shandong Province, a detailed investigation, proven in Changle, a sapphire mining area of over 450 square kilometers, hundreds of millions of carats of reserves, accounting for a total area of the county 1 / 3, and Figure 5 in the Changle, Beiyan such townships circle and found a number of enrichment sapphire mining area, grade-rich area in the 30 g / m 3 above, is by far the largest, the World rare one large sapphire mining area. Moreover, the particles with Changle sapphire crystal intact, pure color, the color of notable gemstones and more specific features such as popular at home and abroad jewellery merchants and consumers of all ages.

(2) The exploitation of the situation. Sapphire found at the beginning in order to speed up the development of the industry, Changle, Changle County proposed a "fast-flow water" policy to encourage families to process, and everyone engage in mosaic. At that time, people are basically using the most primitive tools and approaches alluvial mining. Starting from 1991, we have strengthened the management of resources on sapphire, 1996, Changle county has established a special sapphire mining management office, according to the law of the county sapphire mining management. According to geological survey of the sector, the distinction between sapphire reserves, distribution, quality and other relevant mining conditions, respectively rich region to implement mechanization and semi-mechanization mining, ore to prevent leakage. Lean ore scattered and sporadic corner exploitation of the mining area by the holder to prohibit Luancailuanwa. At present, people mainly in the Commonwealth village individual or organization forms, open-mechanized mining.

¡¡¡¡ The late 1980s and early 1990s, sapphire jewelry to enter the domestic jewellery market, and quickly set off a surge in consumption, Changle sapphire extraction also increased year by year, the 1989-1992 four-year period, Changle sapphire mining volume To 300,700,1250,1500 million carats, precious stones from the initial price of a few dozen per carat increase in the late 1990s, several hundred yuan 1 kt. But at the end of the 1990s, due to the economic crisis in Southeast Asia and the impact of the consumer market sapphire, sapphire domestic consumer market was shrinking, in the jewellery industry was also depressed state. To improve this situation, from 1998 onwards, we adhere to the principles of sustainable development, and doing a good job of sapphire mine development plan, according to law in a planned mining. Do a good job no-take reserves, mining, reclamation area of mineral resources management and ensure that the holder mining. Fine fine to do a good job to make full use of existing processing capacity of the county each year to digest swap a few years ago the development of raw materials, the maximum guarantee of the value of sapphire.

Second. the development of the jewellery industry
