天然的水晶一般都会有絮状（绵绺），也就是大家俗称的瑕疵，这是液体水落石出和二氧化碳的小孔穴，而人工合成的水晶就不会有这样的特征。
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。
A crystal composition concentrates on how the atoms are arranged Within the crystal. Having said that, crystallographers have an interest in the general condition and measurement of your crystal and its external features. To perform this, they have to find out about the crystal program.
③次生包裹体：指主体水晶形成后，由于环境的变化使得主晶周围的一些物质沿裂隙进入到其内部而形成的包裹体。形成的原因有出熔作用、裂隙的结晶化、以及放射性元素破坏的作用等。水晶典型的次生包裹体有胶花水晶中的氧化铁充填物等。
Crystalline composition is characterized by a geometrical, repeating sample of symmetric molecular structure. The arrangement of atoms types these requested, repeating styles.
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。
⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。
Crystals are absolutely nothing greater than an purchased arrangement of molecules or atoms. Crystals can be found in a variety of styles and sizes, and each one has distinctive characteristics. The things they are created of decides how it will form.
水晶是有成色等级之分，影响水晶价位的因素很多，不像钻石以4C就可以判定，所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好，越透越好，颜色越娇嫩越好，形状越典型越好。不过最重要还是自己喜欢，而选购时辨识真伪的方法大致有下列几种：
crystal The newly crystallized quartz grains are characterised by elongate crystals oriented oblique into the shear band margins, defining a standard grain-condition foliation. 来自 Cambridge English Corpus We say the chain topology within the large w location functions as being the proverbial ' scratch-on-theglass ' wanted in the natural chemistry laboratory to produce crystals. 来自 Cambridge website English Corpus The age scatter between the person crystals might mirror incorporation of xenocrysts from earlier magmatic pulses or protoliths. 来自 Cambridge English Corpus The clinopyroxene varieties neutral to pale brown, subhedral to anhedral crystals, sometimes that contains inclusions of plagioclase microlaths and opaque phases.
被主体水晶所捕获的包裹体。原生包裹体通常为固相，形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等，也会见到岩石碎屑或集合体。
水晶的价值还与块体大小有关，同样的颜色和净度级别，块越大越难得。有时候质量级别虽然低一些，但块体够大，也可能价格高于高级别的小晶体
The composition of your sodium atoms by itself, or perhaps the chlorine atoms by itself, is fcc and defines the device cell. The sodium chloride construction So is produced up of two interpenetrating fcc lattices. The cesium chloride lattice (Determine 3A) is based around the bcc framework; every single other atom is cesium or chlorine. In such cases, the unit cell is actually a dice. The third crucial framework for AB
水晶的价值根据品质、块体的大小、美感和产量多少的不同相差较大。遇到好的天然水晶要敢于下手，但好的水晶一般大家都想得到，值与不值，就要看经验了。由于天然水晶的开采和制作原因，没有瑕疵的水晶很难得到，纯净的饰品要达到与合成水晶媲美的品质，实在是很难得。另外，由于水晶的特性，在佩戴过程中，也会改变其等级，比如因为某种原因，有可能会逐渐产生较大裂纹。
