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:

These developments consist of unique buildings with programmable lattice symmetries and well-outlined crystal behaviors, responsive components that leverage the intrinsic properties of nucleic acids to control constructions on need, nanoparticle superlattices grown epitaxially from surfaces and colloidal crystals that supply insights into mild–subject interactions. Hunting ahead, we problem the Neighborhood to leverage the amazing structural Command afforded by crystal engineering with DNA to synthesize classes of functional components that press over and above what has actually been attainable with Obviously taking place crystalline materials or Individuals created by a lot more standard strategies.
Most strong elements found in character exist in polycrystalline variety instead of as just one crystal. They are literally composed of millions of grains (modest crystals) packed with each other to fill all Room. Each particular person grain get more info has a distinct orientation than its neighbours. Although extended-range purchase exists in just just one grain, for the boundary between grains, the ordering modifications way. An average piece of iron or copper (Cu) is polycrystalline.

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。
解理:无解理。所谓解理是指矿物被打击时,沿一定方向有规则地裂开形成光滑平面的性质。根据解理的程度可以分为五类:极完全解理、完全解理、中等解理、不完全解理和无解理,水晶属于无解理。

被主体水晶所捕获的包裹体。原生包裹体通常为固相,形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等,也会见到岩石碎屑或集合体。
Crystals are not merely renowned for their physical physical appearance, but unique crystals of different elements and formations can result in an unlimited number of uses and Actual physical properties.

水晶观赏石是天然水晶中最具代表的作品,具有其他宝石都不具备的观赏性。不论是玉石翡翠还是都要经过雕琢后次能体现他的价值,而水晶观赏石只需要将表面进行抛光,即展现出晶体内所包裹的物质,直接欣赏原汁原味的水晶石。
