This concept applies Similarly in one, two, and 3-dimensional Areas. Your complete crystal lattice is usually produced by repeatedly reproducing the pattern on the device mobile in all directions.
无色水晶以晶莹美丽、洁净透明着称。衡量无色水晶主要看它的纯度，越纯、越透明越好。干净的、无瑕疵的、杂质少的价值就高。无色的水晶如果很脏，就没有利用价值。
人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。
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。
Lattices could have a person lattice issue for each cell or more than one, yielding a complete of fourteen Bravais crystal lattice sorts. Bravais lattices, named for physicist and crystallographer Auguste Bravais, explain the a few-dimensional array produced by a list of discrete factors.
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�?”。
11I carefully opened the offer and found a crystal bell inside of.我小心地打开包裹，发现里面有一个水晶钟。
Metallic Crystals: Metals usually variety metallic crystals, where by a few of the valence electrons are no cost to move all through the lattice. Iron, by way of example, can kind distinctive metallic crystals.
crystal The freshly crystallized quartz grains are characterised by elongate crystals oriented oblique to the shear band margins, defining an average grain-condition foliation. 来自 Cambridge English Corpus We say the chain topology inside the high w region acts as being the proverbial ' scratch-on-theglass ' necessary within the organic and natural chemistry laboratory to produce crystals. 来自 Cambridge English Corpus The age scatter among the the individual crystals may well mirror incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene varieties neutral to pale brown, subhedral to anhedral crystals, at times that contains inclusions of plagioclase microlaths and opaque phases.
用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。
Molecular Crystals: Overall molecules are bonded to each other within an arranged way. An excellent case in point is usually more info a sugar crystal, which consists of sucrose molecules.
《古今小说·李公子救蛇获称心》：“器皿皆是玻璃、水晶、琥珀、玛瑙为之，曲尽巧妙，非人间所有。”
水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手，但好的水晶一般大家都想得到，值与不值，就要看经验了。由于天然水晶的开采和制作原因，没有瑕疵的水晶很难得到，纯净的饰品要达到与合成水晶媲美的品质，实在是很难得。另外，由于水晶的特性，在佩戴过程中，也会改变其等级，比如因为某种原因，有可能会逐渐产生较大裂纹。
