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。

Binary crystals read more are located in quite a few buildings. Some pairs of features type more than one structure. At room temperature, cadmium sulfide may perhaps crystallize either within the zinc blende or wurtzite composition. Alumina also has two probable buildings at home temperature, α-alumina (corundum) and β-alumina. Other binary crystals show diverse structures at different temperatures. One of the most complex crystals are Individuals of silicon dioxide (SiO2), that has 7 different buildings at various temperatures and pressures; the commonest of these buildings is quartz.
