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。
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。
These innovations contain exotic buildings with programmable lattice symmetries and effectively-defined crystal behavior, responsive supplies that leverage the intrinsic Houses of nucleic acids to govern buildings on demand, nanoparticle superlattices developed epitaxially from surfaces and colloidal crystals offering insights into light–issue interactions. Searching forward, we challenge the community to leverage the incredible structural Regulate afforded by crystal engineering with DNA to synthesize lessons of useful resources that drive past what has actually been attainable with Normally happening crystalline products or those created by much more conventional methods.

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。
当二氧化硅结晶完美时就是水晶；结晶不完美的就是石英：二氧化硅胶化脱水后就是玛瑙；二氧化硅含水的胶体凝固后就成为蛋白石；二氧化硅晶粒小于几微米时，就组成玉髓、燧石、次生石英岩。
石英：《广雅》称水晶叫石英，色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释：�?�?，白石英�?”。

Amongst the binary crystals, the simplest constructions to visualise are those with equivalent figures of The 2 different types of atoms. The framework of sodium chloride relies on the dice. To assemble the lattice, the sodium and chlorine atoms are placed on alternate corners of a dice, as well as composition is recurring (Figure 3B).

From your Cambridge English Corpus We say the chain topology inside the higher w area acts as the proverbial ' scratch-on-theglass ' essential within the organic and natural chemistry laboratory to create crystals. From your Cambridge English Corpus Continual-force and temperature molecular-dynamics simulations of crystals of your lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. With the Cambridge English Corpus Besides these, dust particles happen to be noticed in low-temperature plasmas, like Those people Employed in plasma processing and plasma crystals. From the Cambridge English Corpus The ultimate Element of the e book focuses on peculiarities of strongly coupled dusty plasmas, including the formation of dust crystals and affiliated appealing forces. With the Cambridge English Corpus Complete characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. Through the here Cambridge English Corpus Unbroken crystals are euhedral; rounded, or maybe more irregular, primary morphologies were not noticed. Within the Cambridge English Corpus See all samples of crystal These illustrations are from corpora and from sources on the internet. Any opinions while in the illustrations usually do not represent the view of the Cambridge Dictionary editors or of Cambridge University Press or its licensors.
Orthorhombic: These are definitely rhombic prisms and dipyramids that resemble tetragons but without the need of square cross-sections.
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。
