水晶表面坑洼的地方，有的深，有的浅，这是水晶在成长过程中自然形成的，并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体，由于包裹体和水晶结合部位的结合力不强，当表面抛光时，矿体脱落，留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。

A fundamental concept in crystal buildings is the device mobile. It's the smallest unit of quantity that allows equivalent cells being stacked jointly to fill all House. By repeating the sample of the device cell again and again in all directions, the whole crystal lattice is usually built. A dice is The best illustration of a unit mobile. Two other examples are revealed in Figure one. The first would be the device mobile for the confront-centred cubic lattice, and the 2nd is for your system-centred cubic lattice. These constructions are stated in the following paragraphs.
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。

They're going to ultimately produce a pleasant minor uniform cluster of atoms, This is often the whole process of developing crystals. The greater they could occur collectively, the more of the development is going to be visible into the naked eye. Scientists can figure out what mineral They are really investigating by how the crystals sort.

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。
crystal The newly crystallized quartz grains are characterized by elongate crystals oriented oblique to your shear band margins, defining a standard grain-form foliation. 来自 Cambridge English Corpus We say the chain topology inside the superior w area acts as being the proverbial ' scratch-on-theglass ' desired during the natural and organic chemistry laboratory to create crystals. 来自 Cambridge English Corpus The age scatter among the the person crystals may possibly reflect incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene forms neutral to pale brown, subhedral to anhedral crystals, sometimes made up of inclusions of plagioclase microlaths and opaque phases.

水晶饰品越来越受到人们的喜爱。中国、日本、韩国、美国等国家的人们还对水晶球情有独钟，喜欢将它们摆在家里或办公室里，认为水晶球有灵性，能保平安，带来财运。不过天然水晶不像看起来那么晶莹剔透，它也有瑕疵，我们在选购饰品的时候要注意。此外，我们还要掌握水晶的评价依据、选购方法，这样可以帮助我们在琳琅满目的水晶饰品中选到心仪的水晶。
矿物成分：针铁矿、赤铁矿、金红石、磁铁矿、电气石、石榴石、云母、绿泥石等形成了包裹体水晶，如发晶、钛晶、绿幽灵等，发晶中则含有肉眼可见的似头发状的针状矿物的包裹体形成。含锰和铁者称紫水晶；含铁�?；呈金黄色或柠檬�?)称黄水晶；含锰和钛呈玫瑰色者称蔷薇石英，即粉水晶；烟色者称烟水晶；褐色者称茶晶；黑色透明者称为墨晶。
