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。
按照透明度指标，水晶越透明，价格越高，好的透明的水晶加工出的成品晶莹剔透、光辉耀眼。透明度高的水晶能提升颜色的艳丽，否则显得呆板无灵性。光学水晶要求全透明、无双晶、无杂质。工艺水晶要求透明、少裂、少瑕疵。熔炼水晶要求透明，可有较多裂纹。三者价值依次降低，熔炼水晶只能作为熔炼水晶玻璃的原料。在工艺水晶中，晶体较大的，可用来做水晶眼镜和雕刻高档工艺品，因而价格较高。
人造水晶分为熔炼水晶与养殖晶：据水晶专家汪毅的阐述，随着水晶的价值提高，喜欢的人增多，水晶也引起了作伪者的兴趣，现阶段中国水晶市场常见的造假方法为：
Most stable components located in character exist in polycrystalline type in lieu of as an individual crystal. They are literally composed of millions of grains (modest crystals) packed together to fill all Room. Each and every unique grain has a special orientation than its neighbours. Although extended-vary buy exists in just one particular grain, for the boundary among grains, the buying improvements course. An average bit of iron or copper (Cu) is polycrystalline.
You'll find many different crystals based on geometric buildings, crystal advancement, and material. There may be preparations of hexagonal carbon atoms or amethyst which makes hexagonal pyramid buildings.
⑧、雕刻：立体感强，工艺高，做工精细，成本高。分手工雕刻图形、机器雕刻文字。
对任何宝石来说，颜色都是非常重要的，水晶也不例外。如果是水晶晶体是有颜色的，如粉水晶、黄水晶、紫水晶等，其颜色评价的最高标准则是明艳动人，不带有灰色、黑色、褐色等其他色调。如粉水晶，颜色以粉红为佳；紫水晶，要求颜色为鲜紫，纯净不发黑；黄水晶，要求颜色不含绿色、柠檬色调，以金橘色为佳。对于发晶来说，晶体的颜色也是很重要的。相同发丝的金发晶，晶体完全无色（白水晶）和晶体略偏茶色，肉眼的视觉观感也是有差别的，所以前者的价格会高于后者。
Ionic Crystals: Electrostatic forces variety ionic bonds. A basic example is a halite or salt crystal.
Q.4. Exactly what is the distinction between atomic structure and crystal composition? Ans. The principal difference between atomic structure and crystal framework lies within their definitions: atomic structure refers to how atoms are structured in a one molecule or simply a cluster of molecules, Whilst crystal framework considerations the precise arrangement of atoms within a good substance.
颜色：无色，浅至深的紫色，浅黄、中至深黄色，浅至深褐、棕色，绿至黄绿色，浅至中粉红。
With the Cambridge English Corpus We are saying the chain topology within the higher w location functions given that the check here proverbial ' scratch-on-theglass ' needed in the organic chemistry laboratory to make crystals. With the Cambridge English Corpus Continual-tension and temperature molecular-dynamics simulations of crystals from the lecithin fragments - glycerylphosphorylcholine and dilauroylglycerol. From your Cambridge English Corpus Together with these, dust particles happen to be noticed in minimal-temperature plasmas, like These used in plasma processing and plasma crystals. With the Cambridge English Corpus The ultimate Portion of the e book focuses on peculiarities of strongly coupled dusty plasmas, such as the development of dust crystals and involved beautiful forces. In the Cambridge English Corpus Finish characterization of harm threshold in titanium doped sapphire crystals with nanosecond, picosecond, and femtosecond laser pulses. In the Cambridge English Corpus Unbroken crystals are euhedral; rounded, or even more irregular, Major morphologies weren't noticed. From the Cambridge English Corpus See all examples of crystal These illustrations are from corpora and from resources online. Any views in the illustrations usually do not characterize the opinion in the Cambridge Dictionary editors or of Cambridge University Push or its licensors.
Crystals are not simply renowned for his or her physical physical appearance, but unique crystals of different resources and formations may lead to an enormous a number of works by using and Actual physical properties.
《古今小说·李公子救蛇获称心》：“器皿皆是玻璃、水晶、琥珀、玛瑙为之，曲尽巧妙，非人间所有。”
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。
