Not all crystals are Similarly crystalline. There in many cases are impurities, and the ionic & covalent in between molecules can build vastly distinct constructions away from a similar content. A great illustration of this are diamonds and graphene.
⒉棉、云雾或渣状包裹体、杂质在透明水晶内部有雾蒙蒙的现象或是感觉里面像有棉絮状、渣状物质一样的包裹体，这些包裹体的存在，影响水晶的整体美观。还有的水晶内局部含有黑斑或其他颜色的斑状物质，与水晶整体不协调，被视为水晶的杂质，有这种杂质的水晶是次品。
天然水晶是不可再生资源，随着开发的深入，天然水晶存量已越来越少，为了可持续发展，东海县政府早就制定了保护本地资源，鼓励开发海外水晶资源的政策，但是，海外资源也越来越少，很多国家都提高了开采和出口天然水晶的门槛，进入东海市场的外国水晶价格连年暴涨，其中观赏水晶比普通水晶涨价更快。
Fig. seven: A template-directed solution can Management The location of making blocks over a surface area while in the formation of sophisticated constructions.
水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。
Lattices might have one particular lattice stage for each cell or multiple, yielding a total of 14 Bravais crystal lattice sorts. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the 3-dimensional array made by a list of discrete points.
水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位，而对水晶来说，颜色和净度（水晶行业称作晶体）是近乎同等重要的因素：

天然性是水晶观赏石的基本特性。通常整体造型水晶矿物不饰雕琢就具备很高的观赏价值，但是包裹体水晶观赏石经常需要适当打磨抛光，这样更方便观赏水晶内部的包裹体。
There are just a few unique unit-mobile shapes, so numerous crystals share an individual unit-mobile sort. A significant characteristic of a unit mobile is the number of atoms it incorporates. The total range of atoms in the whole crystal more info could be the variety in each cell multiplied by the quantity of device cells. Copper and aluminum (Al) Just about every have one atom for every device mobile, whilst zinc (Zn) and sodium chloride have two. Most crystals have only a few atoms per device mobile, but there are many exceptions. Crystals of polymers, for instance, have 1000s of atoms in each device cell.
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。
The C60 molecules, also called buckyballs, are pretty robust and Pretty much incompressible. Crystals are formed this sort of which the balls are arranged within an fcc lattice by using a just one-nanometre spacing concerning the centres of adjacent balls. The very similar C70 molecule has the shape of a rugby ball; C70 molecules also variety an fcc crystal when stacked collectively. The stable fullerenes kind molecular crystals, with weak binding—supplied by van der Waals interactions—concerning the molecules.
