17These rings are indicative of your crystal structure of nickel and will be discussed only by invoking wavelike Qualities of sunshine.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。
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。
对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正，浓度较高，内部无瑕为好。种类上紫晶最贵，其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。
We have composed about over three hundred stones in the mineral kingdom! Read about Each individual stone's one of a kind origin, history, and energies under.
《全唐诗》卷七八五载《白雪歌》：“鸟啄冰潭玉镜开，风敲檐溜水晶折。”
Lattices may have one particular lattice level for every cell or more than one, yielding a complete of fourteen Bravais crystal lattice forms. Bravais lattices, named for physicist and crystallographer Auguste Bravais, describe the a few-dimensional array made by a list of discrete details.

Crystals are practically nothing in excess of an purchased arrangement of molecules or atoms. Crystals come in a variety of sizes and shapes, and each one has diverse attributes. What they are created of establishes how it'll variety.
包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。
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。
用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。
You will discover other minerals and molecules that will sort these crystal lattices. Snowflakes certainly are a traditional example of a about symmetric and geometrically patterned composition from ice crystals, and gemstones of all varieties are usually crystals.
《古今小说·李公子救蛇获称心》：“器皿皆是玻璃、水晶、琥珀、玛瑙为之，曲尽巧妙，非人间所有。”
The C60 molecules, also known as buckyballs, are very robust and Nearly incompressible. Crystals are formed this kind of the balls are organized in read more an fcc lattice that has a 1-nanometre spacing concerning the centres of adjacent balls. The comparable C70 molecule has The form of the rugby ball; C70 molecules also variety an fcc crystal when stacked jointly. The sound fullerenes sort molecular crystals, with weak binding—supplied by van der Waals interactions—concerning the molecules.
