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。
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。
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。
Large crystals of diamond are beneficial gemstones. The crystal has other fascinating properties; it has the best seem velocity of any good and is the best conductor of warmth. In addition to diamond, the other typical sort of carbon is graphite, which is a layered content. Just about every carbon atom has three coplanar in close proximity to neighbours, forming an arrangement known as the honeycomb lattice. Three-dimensional graphite crystals are attained by stacking equivalent levels.

, has the identical framework, but There are 2 decisions for selecting the holes which the atoms will occupy. The 3rd layer might be put above the atoms of the first layer, creating an alternate layer sequence A
光泽：玻璃光泽。断口处为油脂光泽。光泽，指宝石表面对光线反射的一种光学性质。观察水晶的光泽，可用手握着它，以灯光或窗户投进来的光线看表面反射，透明水晶亮度与光泽强弱有关。
You will find there's identical directive about crystal glass which differentiates amongst total guide crystal, lead crystal and crystal.
第三种是“皮景”，因某些其他的矿物与水晶体共生，或由于其他的物质侵蚀而依附于水晶表面，或者是水晶受自然环境的影响，在水晶表面出现蚀象，形成了一些景象或图案，这种景观存在于水晶表面。
晶体 Silicon crystals developed in the laboratory convert light into electrical Strength. 在实验室中长成的硅晶体可将光线转变为电能。

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（expansion 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」。
14For instance, We have now Quartz crystal clocks and watches correct to within just one minute a year.例如，我们使用的每年误差不超过1分钟的石英水晶钟表和手表。
crystal Alteration is variable: absent in many crystals, in Other individuals generating dense sericite aggregates which may exhibit some recrystallization consequences to produce coarser-grained white mica. From the Cambridge English Corpus The tridymite crystals are rectangular or wedge-shaped and are sometimes organized in aggregates. From the Cambridge English Corpus Moreover, haloarchaeal cells were being embedded within salt crystals underneath laboratory situations and subsequently analysed by mild microscopy. Through the Cambridge English Corpus The white clouds (normally sparse) were also widely considered to be remaining composed of tiny crystals of h2o ice, somewhat like cirrus within our environment. From your Cambridge English Corpus They are present in click here evaporite salt lakes and will be trapped in salt crystals for the duration of evaporation. In the Cambridge English Corpus Thus, the cells (organelles and membranes) are destroyed mechanically by ice crystals, resulting in death by means of mobile lysis. From the Cambridge English Corpus The crystals have been Employed in the main or second orders of reflection. With the Cambridge English Corpus In our 8xperiments, the crystals had been cubes using a foundation space of 8 e mm. From the Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : result of temperature and tension.
