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。
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。
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。
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。

结晶�?When sea drinking water is permitted to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。
⑩、雷射内雕：以计算机辅助激光设备在水晶对象中进行三维图案的成型，艺术效果好，可以任意表达各类图案，图形，达到逼真效果
发晶：无色、浅黄、浅褐等，可因含金红石常呈金黄、褐红等色，含电气石常呈灰黑色；含阳起石而呈灰绿色。
水晶是有成色等级之分，影响水晶价位的因素很多，不像钻石以4C就可以判定，所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好，越透越好，颜色越娇嫩越好，形状越典型越好。不过最重要还是自己喜欢，而选购时辨识真伪的方法大致有下列几种：
A crystal program refers back to the classification of crystals based upon the geometric arrangement and symmetry of their lattice constructions. You will discover seven key crystal systems:
地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
The arrangement of the atom’s electrons establishes its chemical Qualities. The properties of solids are generally predictable from your Attributes in their constituent atoms and molecules, and the several shell constructions of atoms are hence responsible for the variety of solids.
This Assessment chronicles in excess of twenty years of investigation into creating a genetic code for crystal engineering. In lieu of directing Organic processes, this code works by using artificial types of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2D and 3D crystalline architectures, in which just about each and every facet of the resultant structures might be systematically managed. Within this conceptual framework, the structural and practical developments are described in order to determine the current level of sophistication and also to forecast future directions in the platform.
crystal Alteration is variable: absent in several crystals, in others creating dense sericite aggregates which can display some recrystallization outcomes to make coarser-grained white mica. more info Within the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are sometimes arranged in aggregates. Through the Cambridge English Corpus Also, haloarchaeal cells were embedded within salt crystals below laboratory problems and subsequently analysed by gentle microscopy. With the Cambridge English Corpus The white clouds (ordinarily sparse) ended up also extensively regarded as currently being made up of small crystals of h2o ice, fairly like cirrus in our environment. From the Cambridge English Corpus These are present in evaporite salt lakes and might be trapped in salt crystals for the duration of evaporation. In the Cambridge English Corpus Thus, the cells (organelles and membranes) are destroyed mechanically by ice crystals, bringing about Demise by means of cell lysis. From your Cambridge English Corpus The crystals were Utilized in the 1st or second orders of reflection. From the Cambridge English Corpus In our 8xperiments, the crystals have been cubes which has a base place of eight e mm.
