17These rings are indicative of your crystal framework of nickel and can be stated only by invoking wavelike Houses of light.这些光圈表明了了镍的晶体结构，而且只能通过光线中波的特征来解释。
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。
人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
Crystalline composition is characterized by a geometrical, repeating sample of symmetric molecular composition. The arrangement of atoms forms these requested, repeating patterns.
They will ultimately make a nice little uniform cluster of atoms, This is certainly the entire process of expanding crystals. The more they are able to come with each other, the more of the formation will be obvious to your bare eye. Researchers can figure out what mineral These are looking at by how the crystals type.
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�?”。
Crystals is often developed less than average problems from all ninety two Normally transpiring elements besides helium, and helium is usually crystallized at minimal temperatures through the use of twenty five atmospheres of force.
包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。
幽灵水晶，分绿幽灵，红幽灵，白幽灵等，主要组成为绿泥石，其中绿幽灵属于珍贵品种。
看孔眼：对于缀穿水晶制品（如项链、手链、佛珠），要看孔眼是否平直，孔的粗细是否均匀，有无细小裂纹。孔壁必须清澈透明，无“白痕”。
水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
This Review chronicles above twenty years of investigation into making a genetic code for crystal engineering. Rather than directing Organic processes, this code works by using synthetic sorts of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which more info just about just about every aspect of the resultant structures could be systematically controlled. Inside of this conceptual framework, the structural and functional advances are described in an effort to define the present level of sophistication and to predict long term directions with the System.
This crystal construction is chargeable for the special Bodily and chemical Houses of sodium chloride, like its superior melting level, electrical conductivity, and skill to form ionic bonds effortlessly.
