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。

Crystals are wonderful rock formations that have surprised people for Countless a long time. They may be used for a lot of different things, not just for decoration. Lots of the 1st radios ever invented utilised crystals to transmit the radio waves. Some instruments, like quartz watches and laser crystals, use Exclusive Attributes and harmonic abilities of crystals to create very precise measurements and changes.

发晶的价值取决于发的颜色、罕见性及大小,一般是发色鲜艳、块度大的价格高。水胆水晶的价值主要取决于水胆及晶体的大小、透明度的高低。如果水胆较大并有一定形态,便可加工成较为珍贵的工艺品。另外水胆中的水也有一定的科学研究价值,通过它们可了解几百万年前地球上水的成分及变化。

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�?”

断口:贝壳状。断口也叫破口。它是指矿物被打击后产生不规则的破裂,破裂裂面凹凸不平称为断口。根据断口的形状可分为贝壳状和锯齿状。

无色水晶与无色长石因折射率和密度十分接近故较难区分。主要方法是放大检查。长石有两组极完全解理,显微镜下可见两组解理相交而成的“娱蛤状”包裹体或细直的纹理,而水晶则无解理发育,仅有时可见断续不规则的裂理。

石英:《广雅》称水晶叫石英,色白如莹者又叫白。为附的异形字。司马相如《子虚赋》就�?�?雌黄�?�?之句。苏林解释:�?�?,白石英�?”。

The weather are uncovered in a variety of crystal packing preparations. The commonest lattice constructions for metals are Those people attained by stacking the atomic spheres into the most compact arrangement.

仿制钛晶树水晶:钛晶是水晶里价格最昂贵的,造假者当然也不会放过这么好的产品。天然的环境下,在水晶里能生长个像树一样的钛晶,完全是可能的,只是这样的货很少,那我们的造假专家是如何做的呢,白水晶底下打个洞,激光打点成板状的钛晶进去,就这样这块水晶的身价就能飙升几十倍。往往有的钛晶戒面,会采用将钛晶部位割成板状,与圆面的水晶粘合的方法来制作。

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。

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。

⑤、打孔:是在水晶成品未完成前,根据其所需打孔之尺寸及位置,以钻头加工,如制表件、笔筒、瓶孔等。

crystal Alteration is variable: absent in many crystals, in Other individuals making dense sericite aggregates which may display some recrystallization effects to generate coarser-grained white mica. Within the Cambridge English Corpus The tridymite crystals are rectangular or wedge-formed and are sometimes Crystal organized in aggregates. Through the Cambridge English Corpus Additionally, haloarchaeal cells ended up embedded in salt crystals beneath laboratory circumstances and subsequently analysed by gentle microscopy. Through the Cambridge English Corpus The white clouds (commonly sparse) have been also greatly viewed as getting made up of small crystals of drinking water ice, fairly like cirrus in our atmosphere. From the Cambridge English Corpus They're present in evaporite salt lakes and may be trapped in salt crystals through evaporation. From the Cambridge English Corpus Consequently, the cells (organelles and membranes) are destroyed mechanically by ice crystals, leading to death through cell lysis. From your Cambridge English Corpus The crystals have been used in the primary or next orders of reflection. In the Cambridge English Corpus Inside our 8xperiments, the crystals had been cubes having a base area of eight e mm. From your Cambridge English Corpus Vibration-assisted intermolecular hydrogen tunneling in photoreactive doped molecular crystals : effect of temperature and tension.
