Not all crystals are Similarly crystalline. There are often impurities, and the ionic & covalent between molecules can build vastly distinct constructions out of a similar content. An incredible example of this are diamonds and graphene.

③、粗抛光：是将模具压出之毛胚，以金刚石盘直接磨出成品之刻线。④、细抛光：在粗抛光之后，以抛光粉来磨成品至晶莹剔透为止。

A crystal composition focuses on how the atoms are arranged In the crystal. Having said that, crystallographers have an interest in the general shape and dimension from the crystal and its external qualities. To accomplish this, they have to find out about the crystal technique.

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。

结晶�?When sea h2o is permitted to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。

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。

The weather are found in a number of crystal packing preparations. The most common lattice buildings for metals are Those people acquired by stacking the atomic spheres into quite possibly the most compact arrangement.

13Nearly all desktops comprise a quartz-crystal clock to manage their Procedure.几乎所有的计算机都有一个石英晶体时钟来调节它们的运行。

Solids which have small-array order but lack long-array buy are called amorphous. Practically any product is often created amorphous by immediate solidification within the soften (molten condition). This condition is unstable, as well as the stable will crystallize in time. In the event the timescale for crystallization is decades, then the amorphous point out seems stable.

隐晶类水晶外观是一块块的，不是成六角水晶簇状，但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶，因为结晶的体积极为细小，需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑，因为结晶之间有“水化硅石”填补，玛瑙便属于此类。

玉石纹理如果能形成美丽的花纹、图案，其价格就高，如玛瑙内红白相间的色带有规律地排列，形成缠丝玛瑙时，碧玉中的不均匀颜色形成一种风景图案时，材料的价值将提高。当水晶内包裹体形成美丽的图案时，如幽灵水晶、风景水晶，或者针状包裹体呈束状排列时，其价值都高于普通的水晶。图案越美观、越有意境越好。

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。
