A essential thought in crystal buildings would be the device mobile. It is the smallest unit of quantity that allows identical cells to be arranged with each other to occupy all available Area. The geometrical basis of all crystals will be the lattice. A lattice could be viewed as a daily and infinite arrangement of factors or atoms, exactly where each issue or atom has an identical encompassing setting.
水晶文化历史悠久，古人曾赋予它一串极富美感的雅称：水玉、水精、水碧、石英等。
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�?”

在透明的水晶中，隐裂纹呈亮晶晶的片状，有时还会有晕彩效应。这些裂纹是水晶在生长过程中，遇到外力挤压而在内部产生的一些隐形裂纹，隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充，形成愈合的裂纹，也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
Binary crystals are present in a lot of constructions. Some pairs of components type more than one construction. At room temperature, cadmium sulfide may crystallize either in the zinc blende or wurtzite construction. Alumina also has two attainable constructions at room temperature, α-alumina (corundum) and β-alumina. Other binary crystals show unique constructions at distinct temperatures. Among the many most intricate crystals are Individuals of silicon dioxide (SiO2), that has seven distinctive buildings at a variety of temperatures and pressures; the most typical of these buildings is quartz.
