水晶表面坑洼的地方，有的深，有的浅，这是水晶在成长过程中自然形成的，并非是人为造成的损伤。缺陷位置本来包有其他矿物晶体，由于包裹体和水晶结合部位的结合力不强，当表面抛光时，矿体脱落，留下空位。这种缺陷在绿幽灵、钛晶、金发晶上都比较常见。
Bismuth (Bi) appears for being a steel, but the amount of electrons readily available for electrical conduction is analogous to that of semiconductors. In actual fact, bismuth is named a semimetal. Molecular solids are generally crystals fashioned from molecules or polymers. They are often insulating, semiconducting, or metallic, based on the type of molecules while in the crystal. New molecules are continually staying synthesized, and many are made into crystals. The number of distinctive crystals is enormous.
水晶文化历史悠久，古人曾赋予它一串极富美感的雅称：水玉、水精、水碧、石英等。
Tetragonal: These crystals type prisms and double pyramids. The structure is sort of a cubic crystal, apart from one particular axis is for a longer time than the other.
条痕颜色：无色。矿物粉末的颜色叫条痕。它可以消除假色，减弱他色，保留自色，是比矿物的颜色更为可靠的鉴定特征之一。
, has exactly the same structure, but there are two options for selecting the holes which more info the atoms will occupy. The third layer can be put over the atoms of the main layer, making an alternate layer sequence A
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。
There's a similar directive about crystal glass which differentiates amongst whole direct crystal, lead crystal and crystal.
Among the many binary crystals, the simplest constructions to visualize are People with equivalent quantities of The 2 different types of atoms. The composition of sodium chloride is based over a dice. To construct the lattice, the sodium and chlorine atoms are put on alternate corners of a dice, as well as structure is recurring (Figure 3B).
Solids which have small-variety get but lack extensive-variety purchase are termed amorphous. Almost any content is usually designed amorphous by immediate solidification from the soften (molten condition). This affliction is unstable, and the good will crystallize in time. If the timescale for crystallization is a long time, then the amorphous state seems steady.
⑥、丝印：水晶表面附有不同的色料进行效果处理，颜色层面较厚，着力后方可脱落。
隐晶类水晶外观是一块块的，不是成六角水晶簇状，但他们却也是属六方晶系的。但我们不能以肉眼观察到他们的六角形结晶，因为结晶的体积极为细小，需以显微镜协助下才能看到六角开结晶。而此类水晶非常平滑，因为结晶之间有“水化硅石”填补，玛瑙便属于此类。
14For case in point, We've got Quartz crystal clocks and watches exact to inside of one particular minute a yr.例如，我们使用的每年误差不超过one分钟的石英水晶钟表和手表。
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。
