4Without a crystal ball, It is really not possible to state where by we will be next calendar year.不用水晶球预卜未来，我们说不准明年处境如何呀。《牛津词典》
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�?”
Crystalline framework is characterised by a geometrical, repeating pattern of symmetric molecular composition. The arrangement of atoms sorts these purchased, repeating designs.
, has the same structure, but There are 2 options for selecting the holes the atoms will occupy. The 3rd layer might be put around the atoms of the initial layer, generating an alternate layer sequence A
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。
如果水晶内部杂质中有传说中人物的造型，如佛、星座、生肖等价值可能要高于同等颜色和净度的水晶。

The definition of a strong seems obvious; a sound is normally considered staying really hard and organization. On inspection, nevertheless, the definition gets to be less simple. A cube of butter, for instance, is hard after being saved inside a refrigerator which is Evidently a sound.

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。
Crystals are categorized on the whole types, including insulators, metals, semiconductors, and molecular solids. One crystal of the insulator is often transparent and resembles a bit of glass. Metals are shiny Except if they have rusted. Semiconductors are sometimes shiny and often clear but are never rusty. Many crystals may be classified as just one variety of strong, while others have intermediate behaviour. Cadmium sulfide (CdS) may be ready in pure sort and is an excellent insulator; when impurities are additional to cadmium sulfide, it becomes an interesting semiconductor.
