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：

the solid point out of numerous simple substances, which have an everyday shape and surfaces arranged in comparable patterns

结晶的形状非常细小，需要用显微镜才能看得清楚，外观上看起来是平滑、块状。常见最多的是各式玛瑙

条痕颜色：无色。矿物粉末的颜色叫条痕。它可以消除假色，减弱他色，保留自色，是比矿物的颜色更为可靠的鉴定特征之一。

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。

水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。

Being a incredibly hot solution cools or maybe a saturated Alternative evaporates, particles draw near enough for chemical bonds to variety. Crystals may type from deposition directly from the gas stage. Liquid crystals possess particles oriented in an arranged fashion, like reliable crystals, nevertheless are able to movement.

Lots of crystals behave like butter in that they're tricky at read more small temperatures but delicate at larger temperatures. They are named solids whatsoever temperatures down below their melting point. A attainable definition of a solid can be an object that retains its form if remaining undisturbed. The pertinent situation is how much time the article keeps its condition. A very viscous fluid retains its condition for an hour although not a yr. A strong must maintain its shape extended than that.

A crystal process refers back to the classification of crystals based on the geometric arrangement and symmetry of their lattice structures. There are seven major crystal devices:

15The trick to a superb thermoelectric material can be a crystal structure through which electrons can move freely.制造一种好的热电材料的关键是，需要一种电子可以自由流动的晶体结构。

There are actually other minerals and molecules which can variety these crystal lattices. Snowflakes are a typical illustration of a roughly symmetric and geometrically patterned composition from ice crystals, and gemstones of all types are generally crystals.

水精：水晶为何称为水精，《广雅》有巧解：�?水之精灵�?”；李时珍则说：�?莹洁晶光，如水之精英 ”。细加考究，此称还蕴含浓厚的宗教意味呢。水精一名，最初见于佛书，后汉支曜翻译的《具光明定意经》说：�?其所行道，色如水�?�?。

⑥白色的包裹体有蚀变的绿泥石、云母、愈合裂隙、水晶、方解石、透闪石等。
