李商隐，杜牧，白居易，欧阳修，苏轼，呈大昌，辛弃疾，杨万里，吴文英，杨基，魏源等诗坛，词林大家都有歌吟水晶的佳篇传世。

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。

第一种是“全包裹体”，在水晶结晶的时候把这些物质包裹在晶体里面，这类包裹体所形成的各种景象，大多保持了水晶结晶时的原状，也就是说保存了几亿年的原状，极少受到自然环境的影响。

You will also find several elements that resemble crystals but are literally polycrystals. Polycrystals form when microscopic crystals fuse together to sort a solid. These supplies do not include ordered lattices.

, has exactly the same composition, but There are 2 decisions for choosing the holes the atoms will occupy. The 3rd layer might be positioned over the atoms of the 1st layer, generating 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。

发晶：无色、浅黄、浅褐等，可因含金红石常呈金黄、褐红等色，含电气石常呈灰黑色；含阳起石而呈灰绿色。

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。

Solids which have small-selection order but website deficiency prolonged-vary order are called amorphous. Virtually any product could be designed amorphous by immediate solidification through the melt (molten point out). This issue is unstable, as well as solid will crystallize in time. When the timescale for crystallization is several years, then the amorphous condition appears stable.

用手去触摸水晶，天然水晶通常温度要比人造水晶的要凉的多；用眼观察，天然水晶通常有棉絮状的包裹体，这个是人造水晶所没有的。

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。

This crystal composition is liable for the distinctive Actual physical and chemical properties of sodium chloride, which includes its higher melting issue, electrical conductivity, and talent to sort ionic bonds conveniently.
