Xiaobian used to be popular. Although chalcedony and agate are close relatives, they are definitely not a thing. The jade world is so big, we especially like to call some gemstones of polycrystalline and cryptocrystalline aggregates as jade. The human dialect is delicate and moist and transparent, although there are many opaque but well-colored polycrystalline collections. We will also call this. Therefore, we like Hetian jade, jade, agate, chalcedony, jade, and Dongling jade are covered in the jade range. But... never thought that, compared to chalcedony and agate, the chalcedony and crystal are actually the same door? These two things, obviously one is jade, one is a gem, not at all? Agate is going to cry, and the chalcedony wants to smash it and run away with the crystal? Who makes the value of chalcedony and crystal more similar... is not, agate does not accept! Stop it! All are quartz family! There is a very common mineral in nature called quartz, which is one of the most widely distributed minerals on the earth's surface. Yes, it is often used as a precision instrument material or building material. It is like an ancient man who can use it as an axe weapon. Modern people can also use it as a quartz clock or even a variety of precision instruments. In short, it is very versatile. The chemical structure of quartz itself is silicon dioxide (SiO2), which is one of the most common varieties of silicate minerals. Silicate minerals are characterized by containing two elements, silicon (Si) and oxygen (O). Silicate minerals account for 25% of known minerals and 40% of common minerals, not only in the earth, but also in the earth. There is also a large distribution on the moon and meteorites, so quartz is also present on the moon and meteorites. In the gem world, most of the premise of becoming a gemstone is to become a mineral first. Quartz minerals are widely distributed in gemstones, that is, gemstones containing two silicon and one oxygen in the chemical composition, the most common being crystal, Chalcedony and agate, they are different forms of silica, of course more than these three: 1 crystal: The large single crystal obtained by the perfect crystallization of silica will become crystal of different colors when mixed with different coloring elements. For example, it is amethyst after mixing with divalent ferrous iron ions; it is a citrine containing a large amount of iron in a small amount of iron, or a vacant color; if it is containing manganese or titanium, it is a peach powder that is very popular among girls; it is wrapped in needles. Rutile, actinolite, etc. are crystals. 2 Chalcedony: The cryptocrystalline silica aggregate at low temperature and low pressure is chalcedony. Because it is cryptocrystalline, the internal structure is very delicate, the particles are not visible to the naked eye, but occasionally water or bubbles; chalcedony will become different colors of chalcedony after mixing with different elements. 3 Agate: Silica and water are alternately superimposed, and finally formed after dehydration of the gel. The gel water in the middle may be mostly opal. The biggest difference between chalcedony and agate is that the chalcedony is cryptocrystalline so that there are no visible grain particles, etc., agate is striped and so on. 4 Opal: liquid gel. That is to say, the agate is a silica inclusion opal. This opal is the mineral name of Opal, and the excellent quality protein can become opal. Opal is also one of the few non-mineral gemstones in the world. 5 Dongling jade, Miyu, Jinsi jade, Huanglong jade: a variety of polycrystalline cryptocrystalline aggregates, the formation of which is similar to chalcedony, but the more delicate and beautiful, the more it is used as a treasure, in various languages Playing the collection world is also a matter of wind and water. Say that agate is more affordable than chalcedony and crystal? Agate cried... Many people have no value for the jade that is not jade and jade, but there is a general idea that it is jade. Therefore, it is often the case that quartz rock is held on an uncut roadside to ask if it is a good thing or a treasure. If you want to call it "jade", you must first understand that "Shimei is a jade". Many quartz jade quality does not reach the level of "jade". In addition, the price of chalcedony and agate are different, and most of the reasons also appear on the grain road. As for the common quality agate, it is still because the output is much larger than the chalcedony, so the price is very close to the people. If you understand the chalcedony as "the agate without grain" and look at its price, then you may understand why the top varieties of red agate and Gobi stone in agate are expensive, so you can't say that agate must be absolutely Chalcedony and crystal are close to the people, and we must discuss the quality of the variety separately. Even if it is a family, it may be slightly different in genetics, which leads to a difference in price. >>>Agate in the agate world 1 South Red Agate: The price of Nanhong is now hotly fried and has become the third place in the jade world. It is like the warm and delicate of Hetian jade. It will look like jade-like water and bright colors. It is called ancient. "Red Jade", the top of the Qing Dynasty officials wearing a pilgrimage. 2 battle red agate: War Red has not been as hot as South Red, or because it has a mark of agate characteristics, is considered a quality red onyx. However, in the eyes of the Chinese, red is expensive and yellow is respected, so the red and yellow war is still full of extravagance and production is scarce. 3 Gobi stone: also known as a heart agate, bright and translucent, like candy can be seen. In fact, Gobi stone is very close to the chalcedony, and there is no visible impurity in the naked eye. >>>Crystal three nobles 1 Titanium crystal: The white crystal or the tea crystal is the basic crystal, and the hair-like acicular rutile mineral bodies are irregularly arranged inside each other. Different colors of rutile will result in different colors of titanium crystals, and different arrangements will affect different refracted rays. 2 crystal: titanium crystal can be regarded as a fine hair crystal, and the crystal can contain more mineral impurities, such as the original stone black tourmaline containing tourmaline, it will become black crystal; Hair crystal; containing titanium oxide will form a blonde crystal titanium. If the hair is aligned and evenly arranged, the quality is better and the cat's eye effect may occur. 3 Ghost Crystal: It is also known as the crystal of vision, that is, the crystal containing minerals such as volcanic mud. Because of the different forms, volcanic mud will form various shapes in the crystal, which will stimulate people's imagination. Look at the clouds in the sky, what you look like, you can be what shape it is. Green ghost is the most common variety.
