A basic notion in crystal structures will be the unit cell. It is the smallest unit of volume that permits similar cells to become arranged together to occupy all available space. The geometrical basis of all crystals will be the lattice. A lattice might be seen as a regular and infinite arrangement of points or atoms, in which Every single position or atom has The same encompassing atmosphere.
10This is the silicon chip—a little bit chip of silicon crystal.这是硅芯片——一个硅晶体的小芯片。
水碧：《山海经》中，水晶又被称作水碧： �?又南三百里，日耿山，无草木，多水碧 �?，郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用，晋代郭景纯《璞江赋》道�?�?鬼，水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉，水精谓之玉瑛也�?”
Crystalline composition is characterised by a geometrical, repeating sample of symmetric molecular framework. The arrangement of atoms forms these requested, repeating patterns.

Crystals are don't just renowned for their Actual physical visual appeal, but distinctive crystals of different components and formations can lead to an unlimited assortment of uses and physical Houses.
⑤、打孔：是在水晶成品未完成前，根据其所需打孔之尺寸及位置，以钻头加工，如制表件、笔筒、瓶孔等。
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。
