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。

③、粗抛光：是将模具压出之毛胚，以金刚石盘直接磨出成品之刻线。④、细抛光：在粗抛光之后，以抛光粉来磨成品至晶莹剔透为止。

看做工：水晶制品加工过程分为两种，即磨工和雕工。如水晶项链、手链、耳环等属于研磨品；观音像、内画鼻烟壶等属于雕刻品。

Fig. seven: A template-directed solution can control The position of constructing blocks on the area while in the development of sophisticated structures.

. These 4 structures comprise the vast majority of binary crystals with equivalent figures of cations and anions.

第二种是“半包裹体”，在水晶结晶以后，由于受到地球引力的影响而产生的裂隙，晶体外的一些物质通过水晶的裂隙渗透到水晶内部，一部分包裹于水晶之中另一部分露于水晶之外。我们可以看到物质渗进水晶的裂迹，常被称为“通道”，这种包裹体所形成的景象相对地较受自然环境和时间的影响，相应的价值也比较�?。

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。

As a scorching Option cools or simply a saturated Answer evaporates, particles draw near enough for chemical bonds to variety. Crystals also can sort from deposition straight from the gasoline stage. Liquid crystals have particles oriented in an arranged manner, like good crystals, nevertheless can easily move.

Amongst the binary crystals, the best constructions to visualise are Individuals with equivalent numbers of The 2 sorts of atoms. The construction of sodium chloride relies on the dice. To construct the lattice, the sodium and chlorine atoms are placed on alternate corners of the dice, as well as framework is repeated (Determine 3B).

Solids that have short-assortment get but deficiency prolonged-array order are referred to as amorphous. Almost any website content can be made amorphous by rapid solidification within the melt (molten condition). This issue is unstable, and also the sound will crystallize in time. In case the timescale for crystallization is several years, then the amorphous point out seems steady.

Molecular Crystals: Entire molecules are bonded to each other within an structured way. A fantastic illustration is actually a sugar crystal, which contains sucrose molecules.

Crystals are categorised generally types, like insulators, metals, semiconductors, and molecular solids. An individual crystal of the insulator is frequently clear and resembles a piece of glass. Metals are shiny Except if they have rusted. Semiconductors are occasionally shiny and occasionally transparent but are by no means rusty. A lot of crystals is often categorized as just one form of reliable, while others have intermediate behaviour. Cadmium sulfide (CdS) may be ready in pure kind and is a superb insulator; when impurities are extra to cadmium sulfide, it gets an interesting semiconductor.

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。
