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。
Yet another exciting, and delicious, experiment is always to form significant crystals making use of sugar. By heating sugar with h2o after which allowing this Remedy evaporate on sticks, you may sort rock candy from sugar crystals!
A crystal structure concentrates on how the atoms are arranged inside the crystal. However, crystallographers have an interest in the overall condition and dimensions of your crystal together with its external features. To perform this, they have to understand about the crystal program.
Fig. 3: A library of lattice symmetries is usually accessed by changing the particle Main and DNA shell.
. These 4 constructions comprise the majority of the binary crystals with equal quantities of cations and anions.
These illustrations are from corpora and from resources on the internet. Any views in the illustrations never characterize the belief on the Cambridge Dictionary editors or of Cambridge University Press or its licensors.
水晶与高档宝石的净度要求有很大不同。高档宝石稀少罕见，所以一般人们普遍对高档宝石的净度不会过于苛求。而水晶的产量着实大得惊人，所以通常人们会要求水晶净度越高越好，尽量避免有较明显的内含物的水晶。

There are two these feasible periodic arrangements. In Just about every, the main layer has the atoms packed right into a airplane-triangular lattice in which each and every atom has six instant neighbours. Figure two reveals this arrangement for the atoms labeled A
国家还并未给天然水晶提供一个等级划分的具体标准，水晶品种繁杂，每一品种都有他不同的评判标准。
This Evaluate chronicles more than 20 years of exploration into making a genetic code for crystal engineering. Rather then directing biological processes, this code works by using artificial forms of DNA to programme the assembly of nanoparticles and microparticles into 1D, second and 3D crystalline architectures, in which just about each aspect of the resultant structures is often systematically managed. Inside of this conceptual framework, the read more structural and purposeful advancements are explained in an effort to determine the existing volume of sophistication also to forecast future Instructions from the platform.
水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手，但好的水晶一般大家都想得到，值与不值，就要看经验了。由于天然水晶的开采和制作原因，没有瑕疵的水晶很难得到，纯净的饰品要达到与合成水晶媲美的品质，实在是很难得。另外，由于水晶的特性，在佩戴过程中，也会改变其等级，比如因为某种原因，有可能会逐渐产生较大裂纹。
