Not all crystals are equally crystalline. There are frequently impurities, along with the ionic & covalent between molecules can develop vastly distinctive structures from exactly the same substance. A great example of this are diamonds and graphene.
Crystals are attractive rock formations that have stunned individuals for Countless decades. They may be useful for many different things, not just for decoration. Many of the to start with radios at any time invented employed crystals to transmit the radio waves. Some instruments, like quartz watches and laser crystals, use Distinctive properties and harmonic abilities of crystals to generate very precise measurements and changes.
4Without a crystal ball, It is really difficult to state in which we are going to be next 12 months.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》

, has precisely the same composition, but there are two alternatives for selecting the holes the atoms will occupy. The 3rd layer can be positioned around the atoms of the 1st layer, producing an alternate layer sequence A
⑦、镀彩：运用类似电镀的手法在水晶表面以不同的色彩，层面较薄，经摩擦可划伤�?；出现划痕，由于镀彩经常位于底部，因此在镀彩底部经常采用其它对象附着，如生肖文镇。
Hexagonal �?Characterized by 4 axes, three of which happen to be equivalent in length and intersect at a hundred and twenty degrees, by using a fourth axis perpendicular to the other 3.
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：

被主体水晶所捕获的包裹体。原生包裹体通常为固相，形态较规则。水晶中典型的原成包裹体有金红石、电气石、黄铁矿等，也会见到岩石碎屑或集合体。
正常的水晶在生长时，多可以发现和柱形尖端棱线平行的生长纹（progress lines）。由于在地底、岩洞中的生长空间多狭窄，尤其在遇到地震时，或地壳变动时，甚至容易遭到其他矿石的挤压，常常会压迫产生不同的「晶面」。还有，当水晶还是在液态状的时候，常常也会包覆着其他的矿石、泥灰一起结晶成长，如金红石（稍后变成发晶）、火山泥灰（稍后变成幻影水晶）等等。所有的这些，都是「自然的一部分」，请不要视为「瑕疵」。
水玉：中国最古老的称法叫水玉，意谓似水之玉，又说是 �?千年之冰所�?�?。唐代诗人温庭筠《题李处士幽居》写道：�?水玉簪头白角巾，瑶琴寂历拂轻�?”。水玉一词最早频繁出于《山海经》：�?又东三百里，日堂庭之�?…�?多水�?”；�?丹山出焉，东南流注于洛水，其中多水玉 ”；�?逐水出焉，北流注于渭，其中多水玉 ”。司马相如《上林赋》曰�?�?水玉磊河 �?。水晶得名水玉，古人是看�?�?其莹如水，其坚如�?�?的质地。
