看颜色：即使在同一种类的水晶中，它的不同部位的纹理、色泽也各式各有千秋。属于单色的，要色度均匀；在同一块水晶上有深浅的，则要求其色调纹路美观大方。

结晶的形状非常细小，需要用显微镜才能看得清楚，外观上看起来是平滑、块状。常见最多的是各式玛瑙
第一种是“全包裹体”，在水晶结晶的时候把这些物质包裹在晶体里面，这类包裹体所形成的各种景象，大多保持了水晶结晶时的原状，也就是说保存了几亿年的原状，极少受到自然环境的影响。
条痕颜色：无色。矿物粉末的颜色叫条痕。它可以消除假色，减弱他色，保留自色，是比矿物的颜色更为可靠的鉴定特征之一。
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�?。
时尚的收藏爱好者喜欢收藏天然水晶，却常常因为在市场上面对大量的合成水晶看走了眼。市面上的水晶：
As a scorching Remedy cools or possibly a saturated Answer evaporates, particles draw close plenty of for chemical bonds to variety. Crystals could also sort from deposition directly from the gasoline phase. Liquid crystals have particles oriented in an arranged method, like sound crystals, nevertheless will be able to move.
水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：
crystal The recently crystallized quartz grains are characterised by elongate crystals oriented oblique to the shear band margins, defining a standard grain-condition foliation. 来自 Cambridge English Corpus We say the chain topology while in the significant w region functions as being the proverbial ' scratch-on-theglass ' required in the natural chemistry laboratory to make crystals. 来自 Cambridge English Corpus The age scatter amongst the individual crystals could reflect incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene sorts neutral to pale brown, subhedral to anhedral crystals, sometimes made up of inclusions of plagioclase microlaths and opaque phases.
say cheese something that a person who is getting a photograph of you lets you know to mention so that the mouth helps make the shape of a smile
There are just a few different unit-mobile shapes, so many alternative crystals share an individual unit-mobile variety. An important characteristic of the unit mobile is the amount of atoms it is made up of. The overall number of atoms in the whole crystal may be the range in Just about every mobile multiplied by the volume of device cells. Copper and aluminum (Al) each have 1 atom per device mobile, whilst zinc (Zn) and sodium chloride have two. Most crystals have only a few atoms per device cell, but there are some exceptions. Crystals of polymers, as an example, have A huge number of atoms in Every unit cell.
水精：水晶为何称为水精，《广雅》有巧解：�?水之精灵�?”；李时珍则说：�?莹洁晶光，如水之精英 ”。细加考究，此称还蕴含浓厚的宗教意味呢。水精一名，最初见于佛书，后汉支曜翻译的《具光明定意经》说：�?其所行道，色如水�?�?。
Another sort of crystalline carbon relies on a molecule with 60 carbon atoms identified as buckminsterfullerene (C60). The molecular condition is spherical. Just about every carbon is bonded to 3 neighbours, as in graphite, along with the spherical condition is reached by a mixture of 12 rings with 5 sides and twenty rings with 6 sides. Similar buildings were being to start with visualized by the American architect R. Buckminster here Fuller for geodesic domes.
