These crystals were shaped above 1,000,000 a long time back Within the Earth's crust. They come about when the liquid during the Earth consolidates and the temperature chills. Other crystals variety if the liquid makes its way in the clefts and dispense minerals in the clefts.
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。
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。
We have written about above 300 stones while in the mineral kingdom! Examine Just about every stone's exclusive origin, background, and energies beneath.
这种水晶观赏石特指水晶晶簇，它是众多单晶体集中生长在一起的晶体组合。晶簇以其晶莹剔透、独特造型而享誉水晶赏石界。
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。

11I thoroughly opened the package and located a crystal bell within.我小心地打开包裹，发现里面有一个水晶钟。
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。
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。
15The trick to a very good thermoelectric materials is a crystal composition wherein electrons can movement freely.制造一种好的热电材料的关键是，需要一种电子可以自由流动的晶体结构。
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。
The construction in the sodium atoms alone, or maybe the chlorine atoms alone, is fcc and defines the device mobile. The sodium chloride structure So is designed up of two interpenetrating fcc lattices. The cesium chloride lattice (Determine 3A) relies on the bcc composition; every single other atom is cesium or chlorine. In such a case, the unit mobile is really a cube. The 3rd crucial structure for AB
The C60 molecules, also called buckyballs, are rather powerful and Practically incompressible. Crystals are fashioned this kind of the balls are organized in an fcc lattice with a just one-nanometre spacing among the centres of adjacent balls. The very similar C70 molecule has The form of the rugby ball; C70 molecules also type an fcc crystal when stacked click here collectively. The stable fullerenes type molecular crystals, with weak binding—provided by van der Waals interactions—amongst the molecules.
