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。
Crystals are gorgeous rock formations that have astonished human beings for thousands of decades. They may be useful for numerous different things, not just for decoration. Lots of the first radios ever invented used crystals to transmit the radio waves. Some devices, like quartz watches and laser crystals, use special Attributes and harmonic abilities of crystals to create remarkably exact measurements and changes.
结晶的形状非常细小，需要用显微镜才能看得清楚，外观上看起来是平滑、块状。常见最多的是各式玛瑙
If you want to see how crystals are shaped, you may perform a little task in your extremely very own kitchen area and find out the development of the crystals take place with all your have eyes . This can be completed by Placing a small level of table salt into some standard tap h2o, wait 24 hrs, and you may see pleasant cubed formations. This happens because the h2o is evaporating, which results in the atoms that make up the salt (the mineral) as well as drinking water to come closer jointly.
断口：贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂，破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。
你们都知道，拿起一个水晶棱镜，让一束阳光通过它，就会得到一个光谱，看起来就像一条连续的彩虹色带。
Crystals glimpse special from a number of other rocks and minerals, but �?barring a few Particular conditions �?nearly all minerals conceal a crystalline framework beneath the floor.
You will find a related directive about crystal Crystal glass which differentiates between comprehensive direct crystal, guide crystal and crystal.
Among the many binary crystals, the best buildings to visualise are All those with equal numbers of the two forms of atoms. The construction of sodium chloride relies on a dice. To build the lattice, the sodium and chlorine atoms are placed on alternate corners of the dice, along with the composition is repeated (Determine 3B).
晶体 Silicon crystals developed in the laboratory convert mild into electrical Electrical power. 在实验室中长成的硅晶体可将光线转变为电能。
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。
正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（growth strains）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
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。
This crystal framework is to blame for the distinctive physical and chemical Qualities of sodium chloride, such as its large melting position, electrical conductivity, and talent to sort ionic bonds quickly.
