水晶表面坑洼的地方，有的深，有的浅，这是水晶在成长过程中自然形成的，并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体，由于包裹体和水晶结合部位的结合力不强，当表面抛光时，矿体脱落，留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。

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。
Most good elements found in nature exist in polycrystalline sort rather than as a single crystal. They are actually made up of millions of grains (little crystals) packed alongside one another to fill all space. Every single personal grain has another orientation than its neighbours. Although long-vary purchase exists within a person grain, in the boundary in between grains, the buying changes way. A typical piece of iron or copper (Cu) is polycrystalline.
根据美国已经了解的情况，统计局的专家和其他人口统计学家在他们的视野中提供了一个不可抗拒的水晶球。

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。
The weather are identified in many different crystal packing preparations. The most common lattice structures for metals are Those people attained by stacking the atomic spheres into by far the most compact arrangement.
包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。

Single crystals of metals are gentle and malleable, though polycrystalline metals are tougher and stronger and are more helpful industrially. Most polycrystalline resources could be produced into huge one crystals following extended heat procedure. Previously blacksmiths would heat a piece of metal to really make it malleable: warmth tends to make a few grains grow substantial by incorporating more compact types. The smiths would bend the softened steel into shape after which pound it awhile; the pounding would help it become polycrystalline all over again, growing its toughness.
The sodium chloride Crystal crystal lattice is characterized with the shut packing with the optimistic sodium ions and adverse chloride ions. Each sodium ion is surrounded by 6 chloride ions, and every chloride ion is surrounded by 6 sodium ions, making a extremely stable and symmetrical structure.
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。
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。
