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：

4Without a crystal ball, It truly is unachievable to say the place we are going to be following yr.不用水晶球预卜未来，我们说不准明年处境如何呀。《牛津词典》
If you'd like to see how crystals are fashioned, you could perform a little job as part of your incredibly individual kitchen area and see the development in the crystals take place with your have eyes . This can be done by putting a little degree of desk salt into some normal faucet drinking water, wait 24 hrs, and you may see good cubed formations. This happens as the water is evaporating, which brings about the atoms that make up the salt (the mineral) as well as drinking water to come back nearer jointly.
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。
Encyclopaedia Britannica's editors oversee subject matter locations through which they have got comprehensive know-how, regardless of whether from decades of expertise received by focusing on that written content or by using review for a sophisticated degree. They create new written content and validate and edit material acquired from contributors.
根据包裹体和主晶宝石之间形成的先后关系可将水晶的包裹体划分以下三种类�?
The weather are discovered in many different crystal packing arrangements. The most common lattice constructions for metals are All those attained by stacking the atomic spheres into one of the most compact arrangement.

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。
The fundamental units of solids are possibly atoms or atoms which have blended into molecules. The electrons of an atom shift in orbits that type a shell construction round the nucleus. The shells are loaded in a systematic buy, with Every shell accommodating only a small range of electrons. Unique atoms have diverse quantities of electrons, that happen more info to be distributed in a attribute Digital construction of stuffed and partly stuffed shells.
The arrangement of the atom’s electrons establishes its chemical Qualities. The properties of solids are generally predictable from your properties of their constituent atoms and molecules, and different shell constructions of atoms are hence responsible for the range of solids.
压电性：水晶晶体受到压力时会产生电荷；反之，受到电压作用时，晶体会产生频率很高的振动。水晶具有可使压力与电荷相互转移的性能，称压电性。
