Not all crystals are equally crystalline. There are sometimes impurities, plus the ionic & covalent amongst molecules can produce vastly distinct buildings from exactly the same content. An excellent example of this are diamonds and graphene.
杂质、裂纹越少越好。质地好的水晶制品，应看不到星点状、云雾状和絮状分布的气液包裹体或组成玉石的颗粒。有裂纹、斑点，则属于次品。
天然水晶是不可再生资源，随着开发的深入，天然水晶存量已越来越少，为了可持续发展，东海县政府早就制定了保护本地资源，鼓励开发海外水晶资源的政策，但是，海外资源也越来越少，很多国家都提高了开采和出口天然水晶的门槛，进入东海市场的外国水晶价格连年暴涨，其中观赏水晶比普通水晶涨价更快。
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。
You'll find many different crystals based upon geometric structures, crystal development, and materials. There is often preparations of hexagonal carbon atoms or amethyst that makes hexagonal pyramid constructions.
Not all crystals variety in water, but almost all crystals type a similar way, atoms appear with each other and turn into a uniformed cluster. The procedure normally takes as tiny as a few days to it's possible a thousand yrs. Purely natural crystals that originate from the Earth sort the exact same way.
水晶原石观赏石，从字面意义理解：观赏水晶石的原貌，即经过抛光去皮后的包裹体水晶和原色水晶，不需雕刻不求象形就具有非常高的观赏价值和收藏价值。此类水晶观赏石对质地要求非常之高，水晶晶体通透干净，颜色艳丽，意境鲜明深刻的价值就高，它的价值特点就好比钻石，实实在在石头本身的价值。

第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。

The fundamental units of solids are both atoms or atoms which have combined into molecules. The electrons of an atom go in orbits that type a shell structure throughout the nucleus. The shells are crammed in a scientific order, with each shell accommodating only a little amount of electrons. Distinctive atoms have distinct figures of electrons, which are dispersed inside a characteristic electronic framework of filled and partly loaded shells.

在透明的水晶中，隐裂纹呈亮晶晶的片状，有时还会有晕彩效应。这些裂纹是水晶在生长过程中，遇到外力挤压而在内部产生的一些隐形裂纹，隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充，形成愈合的裂纹，也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
