李商隐，杜牧，白居易，欧阳修，苏轼，呈大昌，辛弃疾，杨万里，吴文英，杨基，魏源等诗坛，词林大家都有歌吟水晶的佳篇传世。
Crystals are lovely rock formations that have stunned individuals for 1000s of a long time. They are used for several various things, not just for decoration. Most of the to start with radios ever invented utilized crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use Distinctive properties and harmonic capabilities of crystals for making extremely exact measurements and changes.
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。
看原料：选料精良的水晶制品，应看不到胶口及棉絮；质地纯净、光润、晶莹为好。
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。
你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。
对任何宝石来说，颜色都是非常重要的，水晶也不例外。如果是水晶晶体是有颜色的，如粉水晶、黄水晶、紫水晶等，其颜色评价的最高标准则是明艳动人，不带有灰色、黑色、褐色等其他色调。如粉水晶，颜色以粉红为佳；紫水晶，要求颜色为鲜紫，纯净不发黑；黄水晶，要求颜色不含绿色、柠檬色调，以金橘色为佳。对于发晶来说，晶体的颜色也是很重要的。相同发丝的金发晶，晶体完全无色（白水晶）和晶体略偏茶色，肉眼的视觉观感也是有差别的，所以前者的价格会高于后者。
Crystals are very little much more than an purchased arrangement of molecules or atoms. Crystals come in a number of sizes and shapes, and every one has unique attributes. The things they are created of decides how it'll sort.
水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。

⑥、丝印：水晶表面附有不同的色料进行效果处理，颜色层面较厚，着力后方可脱落。
You'll find only some various unit-cell designs, so a variety of crystals share a single device-mobile kind. A significant attribute of a device mobile is the amount of atoms it consists of. The whole number of atoms in the entire crystal will be the range in Just about every mobile multiplied by the volume of device cells. Copper and aluminum (Al) Each individual have a single atom per unit cell, when zinc (Zn) and sodium chloride have two. Most crystals have only some atoms per device cell, but there are a few exceptions. Crystals of polymers, one example is, have Countless atoms in more info Each individual device cell.

The C60 molecules, also known as buckyballs, are fairly powerful and Just about incompressible. Crystals are formed this kind of which the balls are organized in an fcc lattice having a 1-nanometre spacing in between the centres of adjacent balls. The comparable C70 molecule has the shape of a rugby ball; C70 molecules also type an fcc crystal when stacked jointly. The solid fullerenes variety molecular crystals, with weak binding—provided by van der Waals interactions—among the molecules.
