These crystals have been fashioned above 1,000,000 yrs back inside the Earth's crust. They happen when the liquid from the Earth consolidates and also the temperature chills. Other crystals variety when the liquid can make its way with the clefts and dispense minerals in the clefts.
按照透明度指标，水晶越透明，价格越高，好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽，否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明，可有较多裂纹。三者价值依次降低，熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中，晶体较大的，可用来做水晶眼镜和雕刻高档工艺品，因而价格较高。
A simple notion in crystal buildings is definitely the device mobile. It's the smallest device of volume that allows similar cells to generally be stacked together to fill all space. By repeating the pattern of your unit mobile over and over in all Instructions, the complete crystal lattice could be constructed. A cube is The best example of a unit cell. Two other examples are revealed in Determine one. The 1st could be the unit cell for just a face-centred cubic lattice, and the 2nd is for your body-centred cubic lattice. These structures are described in the following paragraphs.
We have prepared about in excess of 300 stones from the mineral kingdom! Read about Each individual stone's unique origin, history, and energies under.
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
Not all crystals sort in h2o, but nearly all crystals sort the exact same way, atoms arrive with each other and become a uniformed cluster. The procedure can take website as tiny as a few days to possibly a thousand yrs. Normal crystals that come from the Earth form a similar way.
Insert to term list Insert to phrase list [ C/U ] clear rock that appears like ice, or possibly a bit of it
As a hot Alternative cools or possibly a saturated Alternative evaporates, particles attract near sufficient for chemical bonds to type. Crystals also can sort from deposition directly from the gasoline period. Liquid crystals possess particles oriented in an structured fashion, like reliable crystals, nonetheless have the ability to circulation.
Among the many binary crystals, the best buildings to visualise are Those people with equivalent figures of the two kinds of atoms. The composition of sodium chloride is based on the dice. To assemble the lattice, the sodium and chlorine atoms are placed on alternate corners of the dice, along with the construction is recurring (Determine 3B).
看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。
被主体水晶所捕获的包裹体。原生包裹体通常为固相，形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等，也会见到岩石碎屑或集合体。
水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手，但好的水晶一般大家都想得到，值与不值，就要看经验了。由于天然水晶的开采和制作原因，没有瑕疵的水晶很难得到，纯净的饰品要达到与合成水晶媲美的品质，实在是很难得。另外，由于水晶的特性，在佩戴过程中，也会改变其等级，比如因为某种原因，有可能会逐渐产生较大裂纹。
