The characteristics of gemstones in China

The characteristics of gemstones in China
To unbearable on more than 3000 kinds of minerals are known, various types of rock can be said to countless biological products are also varied, but can be used as jewelry, not the total number of more than 200. Why the ratio is so low? The original, this is because there are three basic properties jewelry only meet these three basic requirements of minerals or rocks, may be among the jewels of the temple only. 1. Beautiful
Beauty is the soul of jewelry. US-China jewelry, usually lead embodied in its colors, anyone who has a bright, pleasant, pure colors are considered the top grade, no matter how or even if other conditions, also missed the jewelry. Also involves many other aspects of appearance, such as the gloss is bright, the brightness is dazzling, is crystal clear, there does not matter, "the fire" phenomenon, whether or hinder perception of the flaw so. Additionally, if it has a special optical phenomena, such as the so-called "cat's eye effect", "Star effect", "color effect", "hydrocarbon-color effect", "Solar stone effect", "moonstones effect" and the luminous phenomena, etc. will make even more magnificent gem, more magical, more people love the
2. Rarity
In addition to looking beautiful jewelry, but also a certain "value", it said it would be fewer in order to "Suddenly." There are two rare cases, one is already in production in the medium rare. For example, diamond production is a relatively rare material. According to statistics, even in comparison with the rich diamond mines, people average more than 3 tons of ore mining to get less than 1 carat (1 carat = 0.2 grams) of diamonds; and some of these diamonds because of the shortcomings of one kind or another, but also not employing one, can only be used in industry, of which only a small part of the optional for precious stones, but in processing them into a certain shape of cut, often there will be artificially grinding out 1/3-1/2, therefore, In fact to get a good 1 carat diamond grinding, people on average about 20 tons of ore mining. Another rare condition is caused by processing difficulties. Such as the ancient books in China, has been the pearl agate as a symbol of wealth, visible in the ancient heart of agate is very valuable. This is because the agate is very hard (hardness 7), for the ancients of production behind it, to its refined into a beautiful jade is very difficult. But today, the improvement of production technology, China gemstone wholesalers so that the processing has become much strength does not need to take things in nature as agate combined with diamonds, emeralds that unusual, which makes agate gem abnormalities in rapid decline in status, becoming one each, the price is relatively low middle and low jade.
3. Durable
On the jewelry, the endurance are also important, because only durable can the Dutch Wing Yan Zi jewelry beauty and value of housing. Jewelry durability, performance in physical and chemical properties of both. Physical properties, the most important factor is the hardness. As in nature, quartz is a widely distributed mineral, air, and many quartz dust, and the hardness of quartz is 7, therefore, to ensure long-term wear jewelry forever even after the U.S. beryllium, not quartz The erosion of dust particles, it should require no less than the hardness of quartz jewelry, that is no less than seven. However, due to the natural world to meet the objective hardness of 7 or more jewels are not many, therefore, that although the slightly lower hardness, but to meet the two conditions of beauty and rarity of minerals and rocks, it can still retain the exception in jewelry place. However, they are often relegated to use, attached to the middle and low ranks, but the real expensive China jewelry such as the World recognized the four precious gems - diamonds, red 9, blue) gems, emeralds, chrysoberyl (alexandrite and cat's eye 0, it seven or more. Compared with the physical properties, chemical properties of the stability of the durability of the jewelry is even more important. such as cinnabar, is a bright red with a beautiful and strong gloss of minerals, if only by virtue of these two It may also be a cause for this favorite gem, unfortunately, is its poor chemical stability, in the sunlight it will decompose and destroy, the jewel can not be good.
