诗中“胜美玉”,“过冰清”,写出水晶的质地美,而“亦欲应时明”则描绘出水晶充满灵性的动态美,耐人寻味。罗维是有独特眼光,懂得水晶真谛,第一个称赞水晶超过美玉的伟大诗人。他的认识已被千年之后的科学理论所证实;以水晶为直接吟咏对象的诗篇还有:
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。
A crystal construction focuses on how the atoms are organized inside the crystal. Nonetheless, crystallographers have an interest in the overall form and dimension of your crystal as well as its exterior characteristics. To accomplish this, they should know about the crystal technique.
If you would like see how crystals are formed, you'll be able to do some venture in your extremely very own kitchen and see the formation with the crystals happen using your have eyes . This may be carried out by putting a little level of table salt into some common tap drinking water, wait around 24 hours, and you may see nice cubed formations. This comes about since the water is evaporating, which triggers the read more atoms that make up the salt (the mineral) as well as h2o to come back closer alongside one another.

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。
②固体包裹体:指呈固态相存在包裹体,多因岩浆、热液、变质作用等形成的早期结晶物被水晶捕获而形成。
包裹体常见有固相、固液气三相组合、空洞以及双晶、色带等。水晶中典型的同生包裹体有自形的锐钛矿、气液两相包体等。
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。
天然性是水晶观赏石的基本特性。通常整体造型水晶矿物不饰雕琢就具备很高的观赏价值,但是包裹体水晶观赏石经常需要适当打磨抛光,这样更方便观赏水晶内部的包裹体。
You can find other minerals and molecules which can variety these crystal lattices. Snowflakes can be a common illustration of a roughly symmetric and geometrically patterned composition from ice crystals, and gemstones of all varieties are generally crystals.
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。
The C60 molecules, also called buckyballs, are quite strong and Pretty much incompressible. Crystals are formed these that the balls are organized in an fcc lattice by using a a person-nanometre spacing in between the centres of adjacent balls. The related C70 molecule has the shape of a rugby ball; C70 molecules also variety an fcc crystal when stacked together. The strong fullerenes kind molecular crystals, with weak binding—provided by van der Waals interactions—among the molecules.
