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。
养殖晶：养殖晶是指，用天然水晶做种子，然后赋予天然水晶生长的高压条件，养殖器中有富含二氧化硅的分子。然后二氧化硅分子围绕天然水晶种生长，这样的水晶成分（分子式）与天然水晶是一摸一样的，唯一有差别的是，这样的水晶磁场作用没有天然水晶强。
C2 [ U ] clear glass of pretty top quality, ordinarily with its area Slash into sensitive styles:
Not all crystals type in h2o, but almost all crystals form exactly the same way, atoms come with each other and turn into a uniformed cluster. The procedure might take as little as a few days to it's possible a thousand many years. Organic crystals that come from the Earth sort the identical way.
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：
Crystals can be developed below moderate problems from all 92 Normally transpiring elements apart from helium, and helium is usually crystallized at lower temperatures by using twenty five atmospheres of force.
Crystals will often be considered as some thing of immense natural beauty, and they are commonly made use of with diamonds or other stones to make parts of jewelry. Virtually all crystals now are guy-manufactured in laboratories.
晶体 Silicon crystals developed in a very laboratory convert gentle into electrical Power. 在实验室中长成的硅晶体可将光线转变为电能。
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。
Crystal Lattices You will find seven methods of crystal structures, which happen to be also referred to as lattices or Room lattices:
Crystals are labeled normally Crystal types, including insulators, metals, semiconductors, and molecular solids. One crystal of the insulator is usually clear and resembles a piece of glass. Metals are shiny Except if they have rusted. Semiconductors are occasionally shiny and occasionally clear but are by no means rusty. Quite a few crystals might be categorised as an individual sort of reliable, while some have intermediate behaviour. Cadmium sulfide (CdS) can be ready in pure kind and is a superb insulator; when impurities are added to cadmium sulfide, it becomes a fascinating semiconductor.
对于紫水晶黄水晶这样的单色水晶，通常要观察它的二色性，即使是最顶级的紫水晶黄水晶也是有色差的，通过这个方法可以鉴别是否加色。
