Not all crystals are equally crystalline. There are sometimes impurities, and also the ionic & covalent between molecules can make vastly different buildings from a similar content. An excellent illustration of this are diamonds and graphene.

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 composition focuses on how the atoms are arranged In the crystal. Having said that, crystallographers are interested in the general shape and sizing of the crystal along with its exterior qualities. To perform this, they should find out about the crystal method.

Fig. 3: A library of lattice symmetries is often accessed by switching the particle Main and DNA shell.

Fig. four: Constructing blocks with various styles and area chemistries direct the development of distinct crystal symmetries.

Monoclinic �?Characterized by 3 unequal axes, two of which intersect at an oblique angle, even though the third is perpendicular to the airplane of the other two.

Crystals glance unique from a number of other rocks and minerals, but �?barring a number of Unique circumstances �?almost all minerals disguise a crystalline construction beneath the floor.

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。

水晶是有成色等级之分，影响水晶价位的因素很多，不像钻石以4C就可以判定，所以大家要多听多看多比较才能真正辨别出来。一般的标准是水晶石越大越好，越透越好，颜色越娇嫩越好，形状越典型越好。不过最重要还是自己喜欢，而选购时辨识真伪的方法大致有下列几种：

英语-中文（简体） phrase #beta Beta /beta #preferredDictionaries ^picked title /picked /preferredDictionaries

There click here are 2 these kinds of possible periodic arrangements. In Each and every, the very first layer has the atoms packed into a airplane-triangular lattice in which every atom has 6 speedy neighbours. Determine two reveals this arrangement for your atoms labeled A

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。

⑨、喷砂：立体感弱，较平整，无凹凸感，机器雕刻文字、图形等后进行效果处理。成本低制作快。

This crystal composition is answerable for the distinctive Actual physical and chemical Homes of sodium chloride, like its significant melting stage, electrical conductivity, and talent to sort ionic bonds effortlessly.
