石陨石是来自大气层外的神秘坠物，带着光芒划过天空，引人遐想。几乎所有古代文明都留有关于陨石的记载，一些民族和宗教还将陨石视为圣物，相比之下，我国古人对于陨石的看法则较为客观。早在先秦时期，《左传》中就著有:“陨石，星也”。时至北宋，政治家、科学家沈括曾在《梦溪笔谈》中记载了“于宜兴县民许氏园中”坠落的一枚陨石，称“其大如拳，一头微锐，色如铁，重亦如之”。 据悉，每年降落到地球上的陨石有20多吨，数量有两万多块，其中99%以上是石陨石和铁陨石，石铁陨石只占几乎0.3%左右的比例，换句话说，每年降落到地球上的石铁陨石只有60块左右，其中有一部分陨落在大海，一部分不能被人类发现珍藏，还有一部分被收藏在大型博物馆中。物以稀为贵，正因为此，石铁陨石的商业价值极高，即使是大收藏家，能够收藏到石铁陨石的也寥 寥 无 几。
For the collection of strong dissemination effect to recommend to buyers by the national level expert selection of meteorite treasures, for collectors matchmaking, let thousands of art treasures value was discovered and valued
Weight: 1800 grams
This rock meteorite weighs up to 1800 grams.
Meteorites are pieces of debris from objects in the solar system other than Earth. Most come from asteroids between Mars and Jupiter, but some come from the moon and Mars. Many meteorites have been collected all over the world, and the main composition of stone meteorites is silicate.
Stone meteorites are mysterious falling objects from the atmosphere, with light across the sky, people daydream. Almost all ancient civilizations have recorded meteorites, and some ethnic groups and religions regard meteorites as sacred objects. In contrast, our ancient people had a relatively objective view of meteorites. As early as the Pre-Qin period, "Zuo Zhuan" written: "Meteorites, also star." During the Northern Song Dynasty, shen Kuo, a statesman and scientist, recorded in His book Mengxi Pen Talk that a meteorite fell "in the Minxu Garden of Yixing County", saying that it was "as big as a fist, with a slight sharp head, its color as iron, and its weight as heavy as it". , down to earth every year more than 20 tons, meteorites number has more than twenty thousand, more than 99% of
them are aerolite and iron meteorites, pallasite only accounts for almost 0.3% of proportion, in other words, a year down to the earth's pallasite only about $60, among them are part of the fall in the sea, and part cannot be discovered, and part of the collection in a large museum. The thing with rare for expensive, because of this, the commercial value of stone iron meteorite is extremely high, even if be big collector, can collect stone iron meteorite also very few.
Stone meteorites have what color, the appearance of molten shell: meteorites in the ground before the impact through the dense atmosphere, meteorites in the process of falling and atmospheric friction occurred high temperature, so that the appearance of the formation of a thin layer of molten shell. As a result, the newly fallen meteorites have a dark-colored shell about 1 mm thick. Appearance: In addition, due to the interaction between meteorites and the great airflow, meteorites also leave many impressions on their appearance, like fingerprints pressed by a finger.
With the United States Tucson city professional stone meteorite market as the representative of the European and American countries, stone meteorite collection and trade has been very mature, stone meteorite continues to appreciate, from the price of gold in the 1970s to today's rare stone meteorite per gram of $3,000 to $20,000, the general stone meteorite also reached a few hundred dollars per gram.
Meteorites are irregular and come in a variety of shapes and sizes. Meteorite surface usually have very thin black or dark brown fusion crust, meteorite fusion crust layer is to point to in the process of the atmosphere within the meteorite landing because of the high temperature melt surface, then cooling solidification, when reduced speed meteorites falling within the atmosphere interact with high temperature air after ablation in many natural surface fusion crust texture features. Meteorites are primarily identified by visual observation to see whether they have the characteristics that meteorites should have, that is, the outer molten shell, gas impression, molten streamline, etc. Whether there are spherules, metal spots, etc. Having a wave-like surface, molten flume or vapor print, and black or dark brown crust to identify meteorites.
Its regular shape, with a beautifully shaped meteorite, bright color, surface magma shell fine visible, plus a small amount of metal components, and not with magnetic, can be identified as a stone meteorite, such a large meteorite is now rare in the world. One of its collection investment value is beyond doubt
