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。

These improvements contain unique buildings with programmable lattice symmetries and effectively-defined crystal routines, responsive products that leverage the intrinsic Qualities of nucleic acids to control buildings on desire, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals that provide insights into gentle–issue interactions. Wanting forward, we obstacle the community to leverage the extraordinary structural Command afforded by crystal engineering with DNA to synthesize courses of purposeful materials that push further than what has been possible with Normally happening crystalline products or Individuals created by a lot more standard approaches.
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。

对任何宝石来说，颜色都是非常重要的，水晶也不例外。如果是水晶晶体是有颜色的，如粉水晶、黄水晶、紫水晶等，其颜色评价的最高标准则是明艳动人，不带有灰色、黑色、褐色等其他色调。如粉水晶，颜色以粉红为佳；紫水晶，要求颜色为鲜紫，纯净不发黑；黄水晶，要求颜色不含绿色、柠檬色调，以金橘色为佳。对于发晶来说，晶体的颜色也是很重要的。相同发丝的金发晶，晶体完全无色（白水晶）和晶体略偏茶色，肉眼的视觉观感也是有差别的，所以前者的价格会高于后者。

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。
多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。
In the Cambridge English Corpus We are saying the chain topology while in the significant w location acts as being the proverbial ' scratch-on-theglass ' essential from the natural and organic chemistry laboratory to help make crystals. With the Cambridge English Corpus Continuous-stress and temperature molecular-dynamics simulations of crystals from the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. Within the Cambridge English Corpus In combination with these, dust particles are already noticed in low-temperature plasmas, like Individuals Employed in plasma processing and plasma crystals. With the Cambridge English Corpus The final Element of the e-book focuses on peculiarities of strongly coupled dusty plasmas, including the development of dust crystals and involved eye-catching forces.

21You all understand how once you have a crystal prism and move a beam of daylight via it, you receive a spectrum, which seems like a continual band of rainbow shades.
