诗中“胜美玉”，“过冰清”，写出水晶的质地美，而“亦欲应时明”则描绘出水晶充满灵性的动态美，耐人寻味。罗维是有独特眼光，懂得水晶真谛，第一个称赞水晶超过美玉的伟大诗人。他的认识已被千年之后的科学理论所证实；以水晶为直接吟咏对象的诗篇还有：
杂质、裂纹越少越好。质地好的水晶制品，应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点，则属于次品。

断口：贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂，破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。
结晶�?When sea drinking water is permitted to evaporate, salt crystals are deposited. 海水蒸发后，盐的结晶体就沉淀下来。
⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。

⑤化学稳定�?非常好，在常温下仅溶解于氢氟酸，不溶解于其它各类酸、碱。在高温高压条件下可溶解于碳酸钠溶液中。
From the Cambridge English Corpus We say the chain topology during the higher w area functions given that the proverbial ' scratch-on-theglass ' desired while in the natural chemistry laboratory for making crystals. Through the Cambridge English Corpus Consistent-pressure and temperature molecular-dynamics simulations of crystals with the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. Within the Cambridge English Corpus Together with these, dust particles are noticed in reduced-temperature plasmas, like Those people Employed in plasma processing and plasma crystals. Through the Cambridge English Corpus The final Element of the guide focuses on peculiarities of strongly coupled dusty plasmas, including the development of dust crystals and involved interesting forces. In the Cambridge English Corpus Finish characterization of damage threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. From your Cambridge English here Corpus Unbroken crystals are euhedral; rounded, or maybe more irregular, Major morphologies weren't observed. From your Cambridge English Corpus See all samples of crystal These examples are from corpora and from resources on the internet. Any views from the illustrations tend not to depict the impression with the Cambridge Dictionary editors or of Cambridge College Push or its licensors.
Crystallography could be the analyze of crystals, and it bargains with anything from ideal geometric designs to seemingly random conglomerations of particles and minerals.
⑤、打孔：是在水晶成品未完成前，根据其所需打孔之尺寸及位置，以钻头加工，如制表件、笔筒、瓶孔等。
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。
