Not all crystals are equally crystalline. There tend to be impurities, as well as the ionic & covalent in between molecules can produce vastly different constructions from precisely the same product. A fantastic illustration of this are diamonds and graphene.

23Sometimes, nevertheless, the crystal type of the silicate inclusions is noticed to resemble much more carefully The interior construction of diamond than that of other silicate minerals.然而，有时观察到硅酸盐包裹体的晶体形态比其他硅酸盐矿物更接近金刚石的内部结构。

These advancements incorporate exotic structures with programmable lattice symmetries and nicely-defined crystal behavior, responsive resources that leverage the intrinsic properties of nucleic acids to manipulate structures on need, nanoparticle superlattices grown epitaxially from surfaces and colloidal crystals which offer insights into light-weight–make any difference interactions. Hunting forward, we obstacle the Local community to leverage the amazing structural control afforded by crystal engineering with DNA to synthesize courses of useful supplies that press outside of what continues to be attainable with Normally taking place crystalline resources or Individuals made by extra traditional methods.

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。

发晶，包括钛晶，铜顺发，绿发晶，黑发晶，银发晶，杂色发晶，其中钛晶最珍贵，少数钛晶价值可比钻石，红宝石和蓝宝石以及祖母绿。

损伤是指水晶由于加工或不小心摔掉、碰撞等原因，人为造成的损坏。它可以是破口，也可以是凹坑等。

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。

看文化：水晶里面的包裹体象形，能与文化、宗教及历史有所牵连的话，价格往往会比水晶本身的价值高出几倍甚至几百倍。

. The next layer is shaded from the determine. It's got the same plane-triangular composition; the atoms sit within the holes formed by the initial layer. The very first layer has two equal sets of holes, although the atoms of the second layer can occupy just one set. The 3rd layer, labeled C

Orthorhombic: They're rhombic prisms and dipyramids that resemble tetragons but without having square cross-sections.

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。

Tetragonal �?Characterised by three mutually perpendicular axes, two of which might be equal in length, while the 3rd is lengthier or shorter and here perpendicular to another two.
