看颜色：即使在同一种类的水晶中，它的不同部位的纹理、色泽也各式各有千秋。属于单色的，要色度均匀；在同一块水晶上有深浅的，则要求其色调纹路美观大方。
Bismuth (Bi) seems for being a steel, but the amount of electrons available for electrical conduction is analogous to that of semiconductors. In truth, bismuth is known as a semimetal. Molecular solids are usually crystals shaped from molecules or polymers. They may be insulating, semiconducting, or metallic, with regards to the sort of molecules during the crystal. New molecules are consistently getting synthesized, and lots of are created into crystals. The quantity of different crystals is enormous.
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。

水胆水晶，包括气态，液态，固态，有时候可以同时多态并存，无色居多，个别情况下可见红色，绿色，黄色，蓝色，黑色等。
, has a similar structure, but There are 2 selections for choosing the holes that the atoms will occupy. The 3rd layer could be positioned above the atoms of the main layer, building an alternate layer sequence A
水晶与高档宝石的净度要求有很大不同。高档宝石稀少罕见，所以一般人们普遍对高档宝石的净度不会过于苛求。而水晶的产量着实大得惊人，所以通常人们会要求水晶净度越高越好，尽量避免有较明显的内含物的水晶。
11I cautiously opened the package deal and located a crystal bell inside of.我小心地打开包裹，发现里面有一个水晶钟。
水晶包裹体丰富多彩，从气体、液体到各种矿物质，甚至宝石，均可被包含于水晶内，各种包裹体所形成的景象更是变化万千。按照包裹体的内容，常把包裹体水晶分为一下八类：
crystal The newly crystallized quartz grains are characterized by elongate crystals oriented oblique into the shear band margins, defining a standard grain-form foliation. 来自 Cambridge English Corpus We say the chain topology inside the large w region acts as the proverbial ' scratch-on-theglass ' desired while in the natural chemistry laboratory to generate crystals. 来自 Cambridge click here English Corpus The age scatter among the the person crystals may possibly reflect incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene sorts neutral to pale brown, subhedral to anhedral crystals, at times that contains inclusions of plagioclase microlaths and opaque phases.
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。
Crystals are not merely renowned for his or her physical overall look, but various crystals of different elements and formations may end up in an enormous number of works by using and Actual physical properties.
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。
