27Local economists have appeared into their crystal balls and noticed one thing relatively horrible.当地的经济学者们已预测到将会出现棘手的问题。《柯林斯英汉双解大词典》
the sound condition of numerous easy substances, which have a regular shape and surfaces arranged in comparable styles
对水晶进行评价主要依据其颜色、透明度、大小、净度、特殊图案及是否有光学效应等方面。以颜色纯正，浓度较高，内部无瑕为好。种类上紫晶最贵，其次为黄晶、烟晶、无色水晶和芙蓉石。有特殊光学效应的水晶的价格更高。
水碧：《山海经》中，水晶又被称作水碧： �?又南三百里，日耿山，无草木，多水碧 �?，郭璞注�?�?亦水玉类 ”。这种称谓常被文人所引用，晋代郭景纯《璞江赋》道�?�?鬼，水碧�?�?。水晶又有人称它叫玉瑛。《符瑞图》载�?美石似玉，水精谓之玉瑛也�?”
Crystalline construction is characterized by a geometric, repeating sample of symmetric molecular construction. The arrangement of atoms kinds these ordered, repeating designs.
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。
水晶内部有多种矿物包裹体，形成的各种景观可以肉眼观测，这样的水晶就是包裹体水晶观赏石。由于水晶本身就是宝石，因此人们称誉包裹体水晶为“宝石级的观赏石”。包裹体水晶观赏石都具有独特性，具有极高欣赏和收藏价值。
Ionic Crystals: Electrostatic forces kind ionic bonds. A vintage illustration is really a halite or salt crystal.
Metallic Crystals: Metals usually variety metallic crystals, in which some of the valence electrons are totally free to move all over the lattice. Iron, by way of Crystal example, can type various metallic crystals.
[ C/U ] transparent glass of top of the range, generally with its surface Slash into patterns that replicate gentle
地质学家目前为止对晶洞形成还没有广泛认同的理论，但相信晶洞可以在任何埋藏的空腔内形成。这些空腔可以是火成岩中的气泡、树根下的空穴，甚至动物挖的地洞。经过漫长时间，空腔的外壁变硬，溶解的矽酸盐或方解石沉积到内壁。再经过漫长的时间，缓慢渗入的矿物使得晶体在空腔内部结晶。
You can find only a few diverse device-mobile styles, so a variety of crystals share only one device-mobile type. A vital attribute of the device mobile is the quantity of atoms it includes. The full quantity of atoms in the whole crystal would be the selection in Each individual cell multiplied by the volume of unit cells. Copper and aluminum (Al) Each and every have one atom for every unit cell, though zinc (Zn) and sodium chloride have two. Most crystals have only some atoms for every device mobile, but there are numerous exceptions. Crystals of polymers, one example is, have Many atoms in Just about every unit mobile.
在透明的水晶中，隐裂纹呈亮晶晶的片状，有时还会有晕彩效应。这些裂纹是水晶在生长过程中，遇到外力挤压而在内部产生的一些隐形裂纹，隐裂纹在芙蓉石、紫水晶、白水晶球及白水晶柱中都很常见。有的裂纹后来被物质填充，形成愈合的裂纹，也就是原来的裂纹又长住了。这种裂纹对水晶的影响相对要小一些。
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。
