Not all crystals are equally crystalline. There tend to be impurities, and also the ionic & covalent amongst molecules can make vastly different buildings from the same product. An awesome example of this are diamonds and graphene.
按照透明度指标，水晶越透明，价格越高，好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽，否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明，可有较多裂纹。三者价值依次降低，熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中，晶体较大的，可用来做水晶眼镜和雕刻高档工艺品，因而价格较高。
Chemical Bonds The kinds of chemical bonds shaped concerning atoms or teams of atoms in crystals rely upon their measurement and electronegativity. There are actually four groups of crystals as grouped by their bonding:
第一种是“全包裹体”，在水晶结晶的时候把这些物质包裹在晶体里面，这类包裹体所形成的各种景象，大多保持了水晶结晶时的原状，也就是说保存了几亿年的原状，极少受到自然环境的影响。
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。

The essential units of solids are possibly atoms or atoms that have put together into molecules. The electrons of an atom move in orbits that type a shell structure around the nucleus. The shells are loaded in a scientific order, with more info Each and every shell accommodating only a small variety of electrons. Different atoms have unique numbers of electrons, that are distributed in a characteristic electronic construction of crammed and partly stuffed shells.
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。
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。
