其它描述：《庶物异名疏》中说： �?水精出大秦国，一名黎�?�?。结晶完整的水晶晶体，就如参差交错的马齿，所以人们又叫它马牙石。先民们最早用它研磨成眼镜片，因而送它一个眼镜石的绰号。水晶有通称，也有俗称。广州一带称水晶叫晶玉，又名鱼脑冻；江苏东海县山民发现水晶会 �?窜火�?�?，于是给它起个放光石的俗名。世间一物多名，不足为奇，而像水晶拥有这么多的别称，实不多见。瞧，从水玉、水碧、白玉、玉瑛、水精石英、黎难、晶玉到菩萨石、马牙石、眼镜石、放光石、千年冰、高山冻、鱼脑冻等等，简直构成一部奇石鉴赏史。
杂质、裂纹越少越好。质地好的水晶制品，应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点，则属于次品。
晶及其石英岩类玉石是中低档宝玉石，虽比不上钻石、红蓝宝石的高贵，但在加工中如果构思巧妙而且加工精细，同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
Fig. 3: A library of lattice symmetries is usually accessed by altering the particle core and DNA shell.
There are many different crystals based upon geometric buildings, crystal progress, and content. There might be preparations of hexagonal carbon atoms or amethyst which makes hexagonal pyramid constructions.
第二种是“半包裹体”，在水晶结晶以后，由于受到地球引力的影响而产生的裂隙，晶体外的一些物质通过水晶的裂隙渗透到水晶内部，一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹，常被称为“通道”，这种包裹体所形成的景象相对地较受自然环境和时间的影响，相应的价值也比较�?。
石英：《广雅》称水晶叫石英，色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释：�?�?，白石英�?”。
②固体包裹体：指呈固态相存在包裹体，多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。
Among the binary crystals, the best constructions to visualize are People with equal numbers of the two varieties of atoms. The composition of sodium chloride relies on the dice. To build the lattice, the sodium and chlorine atoms are put on alternate corners of a cube, and also the framework is repeated (Determine 3B).

国家还并未给天然水晶提供一个等级划分的具体标准，水晶品种繁杂，每一品种都有他不同的评判标准。
水晶饰品越来越受到人们的喜爱。中国、日本、韩国、美国等国家的人们还对水晶球情有独钟，喜欢将它们摆在家里或办公室里，认为水晶球有灵性，能保平安，带来财运。不过天然水晶不像看起来那么晶莹剔透，它也有瑕疵，我们在选购饰品的时候要注意。此外，我们还要掌握水晶的评价依据、选购方法，这样可以帮助我们在琳琅满目的水晶饰品中选到心仪的水晶。
crystal Alteration is variable: absent in lots of crystals, in Many others producing dense sericite aggregates which may display some recrystallization consequences to generate coarser-grained white mica. Within the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are sometimes organized in aggregates. Through the Cambridge English Corpus Moreover, haloarchaeal cells ended up embedded in salt crystals below laboratory ailments and subsequently analysed by gentle microscopy. Through the Cambridge English Corpus The white clouds (generally sparse) ended up also commonly considered getting made up of tiny crystals of drinking water ice, rather like cirrus within our atmosphere. In the Cambridge English Corpus They're located in evaporite salt lakes and might be trapped in salt crystals in the course of evaporation. With the Cambridge English more info Corpus Consequently, the cells (organelles and membranes) are ruined mechanically by ice crystals, resulting in Demise by means of mobile lysis. In the Cambridge English Corpus The crystals have been used in the 1st or next orders of reflection. Through the Cambridge English Corpus Within our 8xperiments, the crystals were being cubes with a foundation spot of eight e mm. Within the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : result of temperature and tension.
