天然的水晶一般都会有絮状（绵绺），也就是大家俗称的瑕疵，这是液体水落石出和二氧化碳的小孔穴，而人工合成的水晶就不会有这样的特征。
⒉棉、云雾或渣状包裹体、杂质在透明水晶内部有雾蒙蒙的现象或是感觉里面像有棉絮状、渣状物质一样的包裹体，这些包裹体的存在，影响水晶的整体美观。还有的水晶内局部含有黑斑或其他颜色的斑状物质，与水晶整体不协调，被视为水晶的杂质，有这种杂质的水晶是次品。
A crystal framework focuses on how the atoms are arranged Within the crystal. Even so, crystallographers are interested in the general form and size of the crystal in addition to its exterior qualities. To perform this, they need to understand about the crystal process.
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。
根据美国已经了解的情况，统计局的专家和其他人口统计学家在他们的视野中提供了一个不可抗拒的水晶球。
结晶�?When sea h2o is allowed to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。
Springer Mother nature remains neutral with regards to jurisdictional statements in revealed maps and institutional affiliations.
Crystals can be grown less than reasonable disorders from all ninety two By natural means developing components besides helium, and helium might be crystallized at very low temperatures through the use of 25 atmospheres of strain.
水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。
晶体 Silicon crystals developed in a very laboratory change light into electrical Electrical power. 在实验室中长成的硅晶体可将光线转变为电能。
. The second layer is shaded inside the figure. It's exactly the same airplane-triangular composition; the atoms sit from the holes shaped by the primary layer. The initial layer has two equal sets of holes, although the atoms of the next layer can occupy only one established. The third layer, labeled C
Molecular Crystals: Whole molecules click here are bonded to each other within an arranged fashion. A superb example is usually a sugar crystal, which is made up of sucrose molecules.
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 structures. Some pairs of components form multiple composition. At home temperature, cadmium sulfide may crystallize possibly within the zinc blende or wurtzite structure. Alumina also has two feasible buildings at area temperature, α-alumina (corundum) and β-alumina. Other binary crystals exhibit distinct buildings at diverse temperatures. One of the most sophisticated crystals are These of silicon dioxide (SiO2), which has 7 various structures at a variety of temperatures and pressures; the most typical of these constructions is quartz.
