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：
12He experimented with once more in quite a few other metropolitan areas and succeeded with Crystal Caramels.他又在其他几个城市再次尝试，并成功制出了水晶焦糖。
一般而言，紫晶和黄晶是水晶中价值较高的品种。两者进一步的分级是据其颜色的深浅，颜色较深的为A级，稍浅的为B级。一般颜色较深的价格高，但要以不深暗为标准。颜色包括两种，一种是水晶本身的颜色，另一种是内部包裹体的颜色。水晶本身的颜色要艳丽、纯正，分布要均匀，不能太深或太浅，如澳州玉、蓝玉髓、紫晶、黄水晶，其价格就高。无色的水晶内含包裹体的颜色艳丽，其价格也高，如钛晶、绿幽灵、红兔毛。紫水晶一般以稍有云状物、颜色深紫、晶体通透的为上品。
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。
How Crystals Kind The entire process of forming a crystal is known as crystallization. Crystallization typically takes place any time a strong crystal grows from the liquid or solution.
⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
Springer Nature stays neutral regarding jurisdictional statements in printed maps and institutional affiliations.
Ionic Crystals: Electrostatic forces variety ionic bonds. A common example is usually a halite or salt crystal.
Cite Even though every effort and hard work has actually been produced to observe citation style rules, there might be some discrepancies. You should seek advice from the right design and style handbook or other resources Should you have any issues. Pick out Citation Design and style
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。
地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
⑨、喷砂：立体感弱，较平整，无凹凸感，机器雕刻文字、图形等后进行效果处理。成本低制作快。
crystal Alteration is variable: absent in several crystals, in Many others producing dense sericite aggregates which can show some recrystallization results to create coarser-grained white mica. From the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are sometimes arranged in aggregates. From the Cambridge English Corpus Additionally, haloarchaeal cells had been embedded within salt crystals underneath laboratory disorders and subsequently analysed by gentle microscopy. With the Cambridge English Corpus The white clouds (commonly sparse) were also extensively viewed as being composed of small crystals of h2o ice, somewhat like cirrus within our atmosphere. Through the Cambridge English Corpus They are located in evaporite salt lakes and might be trapped in salt crystals all through evaporation. With the Cambridge English Corpus Thus, the cells (organelles and membranes) are wrecked mechanically by ice crystals, leading to Dying more info as a result of mobile lysis. From your Cambridge English Corpus The crystals have been Employed in the first or second orders of reflection. With the Cambridge English Corpus Inside our 8xperiments, the crystals ended up cubes that has a base area of eight e mm. With the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : outcome of temperature and tension.
