17These rings are indicative in the crystal composition of nickel and will be stated only by invoking wavelike properties 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。
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。
You can find many various crystals dependant upon geometric structures, crystal progress, and material. There might be preparations of hexagonal carbon atoms or amethyst which makes hexagonal pyramid structures.
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：
损伤是指水晶由于加工或不小心摔掉、碰撞等原因，人为造成的损坏。它可以是破口，也可以是凹坑等。
Q.4. Exactly what is the distinction between atomic framework and crystal structure? Ans. The primary distinction between atomic structure and crystal construction lies within their definitions: atomic construction refers to how atoms are arranged in just a single molecule or maybe a cluster of molecules, whereas crystal structure issues the specific arrangement of atoms inside a good material.
The definition of a stable appears clear; a stable is mostly considered staying tricky and organization. Upon inspection, however, the definition turns into significantly less straightforward. A cube of butter, for example, is difficult after being saved in a fridge and is particularly Obviously a stable. After remaining on the kitchen area counter for per here day, precisely the same cube gets pretty delicate, and it truly is unclear Should the butter really should continue to be considered a strong.
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。
Molecular Crystals: Complete molecules are bonded to each other within an structured fashion. A superb instance is really a sugar crystal, which has sucrose molecules.
This Evaluation chronicles in excess of twenty years of investigate into creating a genetic code for crystal engineering. Rather then directing Organic procedures, this code works by using synthetic types of DNA to programme the assembly of nanoparticles and microparticles into 1D, 2D and 3D crystalline architectures, in which almost every facet of the resultant buildings can be systematically managed. Inside this conceptual framework, the structural and purposeful advances are described in an effort to define the current degree of sophistication and to forecast potential directions in the System.
Fig. five: The ability to realize described crystal behavior is depending on the symmetry engineering strategy.
