A sound is crystalline if it's got extended-selection get. As soon as the positions of an atom and its neighbours are recognized at just one issue, the position of each and every atom is understood specifically all over the crystal. Most liquids deficiency extensive-array order, Though several have brief-range order. Shorter variety is described as the primary- or 2nd-nearest neighbours of the atom. In many liquids the first-neighbour atoms are organized in precisely the same construction as inside the corresponding strong phase.

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。
Substantial crystals of diamond are valuable gemstones. The crystal has other exciting Houses; it's got the highest seem velocity of any strong and is the best conductor of heat. Other than diamond, the other prevalent kind of carbon is graphite, and that is a layered product. Just about every carbon atom has 3 coplanar in close proximity to neighbours, forming an arrangement called the honeycomb lattice. Three-dimensional graphite crystals are attained by stacking identical levels.
There are actually many different crystals determined by geometric constructions, crystal expansion, and materials. There could be arrangements of hexagonal carbon atoms or amethyst which makes hexagonal pyramid buildings.
无色水晶与无色长石因折射率和密度十分接近故较难区分。主要方法是放大检查。长石有两组极完全解理，显微镜下可见两组解理相交而成的“娱蛤状”包裹体或细直的纹理，而水晶则无解理发育，仅有时可见断续不规则的裂理。
⑩、雷射内雕：以计算机辅助激光设备在水晶对象中进行三维图案的成型，艺术效果好，可以任意表达各类图案，图形，达到逼真效果
Crystals are absolutely nothing a lot more than an purchased arrangement of molecules or atoms. Crystals are available in a number of sizes and shapes, and each one has different characteristics. Whatever they are made of determines how it will eventually variety.
仿制钛晶树水晶：钛晶是水晶里价格最昂贵的，造假者当然也不会放过这么好的产品。天然的环境下，在水晶里能生长个像树一样的钛晶，完全是可能的，只是这样的货很少，那我们的造假专家是如何做的呢，白水晶底下打个洞，激光打点成板状的钛晶进去，就这样这块水晶的身价就能飙升几十倍。往往有的钛晶戒面，会采用将钛晶部位割成板状，与圆面的水晶粘合的方法来制作。

Orthorhombic: These are rhombic prisms and dipyramids that resemble tetragons but devoid of sq. cross-sections.
⑤、打孔：是在水晶成品未完成前，根据其所需打孔之尺寸及位置，以钻头加工，如制表件、笔筒、瓶孔等。
The C60 molecules, also referred to as buckyballs, are very powerful and Just about incompressible. Crystals are shaped these kinds of which the balls are arranged in an fcc lattice that has a 1-nanometre spacing amongst the centres of adjacent balls. The identical C70 molecule has the shape of the rugby ball; C70 molecules also variety an fcc crystal when stacked alongside Crystal one another. The strong fullerenes kind molecular crystals, with weak binding—provided by van der Waals interactions—in between the molecules.
