Meteorite, also known as \"meteorite\", is an unburned stone, iron or a mixture of stone and iron, which is scattered on the surface of the earth or other planets by cosmic meteors or dust fragments that deviate from the original orbit outside the earth. Because meteorites are objects from outer space, it is necessary to identify whether meteorites are true or false by instruments, and the naked eye has only an auxiliary role. Most meteorites come from the asteroid belt between Mars and Jupiter, and a few come from the moon and Mars. Meteorites can be roughly divided into stone meteorites, iron meteorites and stone-iron mixed meteorites. The average density of meteorites is between 3 and 3.5, and the main component is silicate. The density of meteorite iron is 7.5~8.0, which is mainly composed of iron and nickel. The composition of stony iron is between them, and the density is between 5.5 and 6.0.
For thousands of years, agate meteorite, as a rare treasure, has always been pursued tirelessly by collectors, and has even been sincerely praised as \"the king of minerals\" and \"the king of precious stones\". Moreover, agate meteorite also has a very nice name \"lonsdale\", which means that agate meteorite is formed after meteors in space fall into the earth and burn and melt. Agate meteorite contains many elements such as carbon, magnesium, zinc and so on. These elements make agate meteorites appear more transparent, delicate and beautiful in the dark
