看颜色：即使在同一种类的水晶中，它的不同部位的纹理、色泽也各式各有千秋。属于单色的，要色度均匀；在同一块水晶上有深浅的，则要求其色调纹路美观大方。
无色水晶以晶莹美丽、洁净透明着称。衡量无色水晶主要看它的纯度，越纯、越透明越好。干净的、无瑕疵的、杂质少的价值就高。无色的水晶如果很脏，就没有利用价值。
晶及其石英岩类玉石是中低档宝玉石，虽比不上钻石、红蓝宝石的高贵，但在加工中如果构思巧妙而且加工精细，同样具有很高的价值。如中国传统的玛瑙“虾盘”、“龙盘”、“水漫金山�?水胆玛瑙摆件)都被誉为国家级宝玉石。
If you'd like to see how crystals are fashioned, you can do some challenge inside your really possess kitchen area and see the formation of the crystals take place together with your have eyes . This may be carried out by Placing a little degree of table salt into some regular faucet water, hold out 24 hrs, and you may see pleasant cubed formations. This comes about because the drinking water is evaporating, which leads to the atoms that make up the salt (the mineral) plus the drinking water to come back nearer jointly.
2She was carrying a strand of crystal beads.她戴着一串水晶珠子。《柯林斯英汉双解大词典》
Not all crystals sort in water, but nearly all crystals type precisely the same way, atoms appear jointly and become a uniformed cluster. The process normally takes as minor as a couple of days to possibly a thousand decades. Organic crystals that originate from the Earth kind a similar way.
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。
损伤是指水晶由于加工或不小心摔掉、碰撞等原因，人为造成的损坏。它可以是破口，也可以是凹坑等。
水晶常以晶簇、晶洞形式产出，其中水晶洞一般存在于由火山喷发而形成的巨厚熔岩流层的火成岩与玄武岩中。火山喷发时所含的气体或热水溶蚀等作用导致岩层中出现大量的孔隙，当富含硅质矿物的流体进入较薄的熔岩孔隙中，且温、压条件合适时将结晶沉淀出水晶等矿物。
多色�?无色水晶没有多色性。有色水晶有弱到强的多色�?表现为体色的不同深浅。
15The trick to a superb thermoelectric content is often a crystal structure during which electrons can stream freely.制造一种好的热电材料的关键是，需要一种电子可以自由流动的晶体结构。
Crystallography may be the examine of crystals, and it discounts with every thing from perfect geometric designs to seemingly random conglomerations of particles and minerals.
The framework from the sodium atoms alone, or perhaps the chlorine atoms on your own, is fcc and defines the unit cell. The sodium chloride composition Hence is made up of two interpenetrating fcc lattices. The cesium chloride lattice (Figure 3A) is based to the bcc construction; every other atom is cesium or chlorine. In such a case, the device mobile is a dice. The 3rd crucial Crystal structure for AB
水晶观赏石在形态、质地、内部特征等方面往往十分奇异。大自然有无限风光，都可以在包裹体水晶种找到缩影。
