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:

晶及其石英岩类玉石是中低档宝玉石,虽比不上钻石、红蓝宝石的高贵,但在加工中如果构思巧妙而且加工精细,同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
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。

, has exactly the same framework, but There are 2 options for choosing the holes that the atoms will occupy. The 3rd layer is often placed around the atoms of the primary layer, building an alternate layer sequence A
水晶的评价标准和高端宝石有所不同。多数高端宝石把颜色放在评价的第一位,而对水晶来说,颜色和净度(水晶行业称作晶体)是近乎同等重要的因素:
11I diligently opened the deal and found a crystal bell inside.我小心地打开包裹,发现里面有一个水晶钟。
第三种是“皮景”,因某些其他的矿物与水晶体共生,或由于其他的物质侵蚀而依附于水晶表面,或者是水晶受自然环境的影响,在水晶表面出现蚀象,形成了一些景象或图案,这种景观存在于水晶表面。
Crystals with obvious flat faces are termed euhedral crystals, even though These lacking defined faces are termed anhedral crystals. Crystals consisting of ordered arrays of atoms that are not normally periodic are termed quasicrystals.
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。
The read more arrangement of the atom’s electrons decides its chemical Houses. The properties of solids are often predictable within the Homes in their constituent atoms and molecules, and the several shell buildings of atoms are as a result liable for the diversity of solids.
Crystals are categorised on the whole categories, for instance insulators, metals, semiconductors, and molecular solids. One crystal of the insulator is often clear and resembles a bit of glass. Metals are shiny unless they've got rusted. Semiconductors are occasionally shiny and occasionally transparent but are by no means rusty. Many crystals may be categorized as an individual style of stable, while some have intermediate behaviour. Cadmium sulfide (CdS) can be organized in pure form and is a wonderful insulator; when impurities are additional to cadmium sulfide, it gets to be an interesting semiconductor.
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。
